Infrared Basics
All solid bodies when having temperatures above
the absolute zero (-273 C) emit electromagnetic
waves. The range of longer wave lengths beyond
the visual spectrum is referenced as infrared ra-
diation. The scientist Wilhelm Wien (1864–1928)
has described the relation between a solid body’s
temperature and its emitting peak wave length by
following equation:
λmax =2898 / T
T = Temperature in K (Kelvin)
λ = Wavelength in µm
Using this law we can calculate the specific peak
emission wave length of any material or body: A
human body, of a surface temperature of approx.
35°C or 308 K calculates into a peak wavelength
of 9,4 µm; a cat of 38°C temperature into 9,3 µm.
According to Max Planck (1858 – 1947) the inten-
sity curve of all emitted wave lengths for a solid
body is rather broad. For our example above this
means we cannot distinguish human from the cat
by their infrared spectrum.
For various temperatures of an ideal black body
radiator the intensity curves of radiated energy
versus wave length are shown below.
Infrared Detectors
With detectors for the infrared spectrum there
are two major classes by their physical principles:
Photon Detectors and Thermal Detectors. Photon
detectors convert radiation directly into electrons,
Thermal Detectors receive radiation, transfer it to
raising temperature of the sensing material which
changes it’s electrical property in response to the
temperature rise. Photon detectors such as Photo-
diodes and Phototransistors range from visible to
near infrared, Thermal Detectors have a broad re-
sponse from below visible light up to over 100 µm.
Fitted with special infrared windows as spectral
filters they work in the mid to far infrared range
without ambient visible light interference.
Filters for Infrared Sensors
The spectral sensitive range of the detectors is
defined by a filter window. Common applications
in infrared reference wavelengths from 2 to 20
µm. Infrared windows for pyrometric applications
are defined for the atmospheric window 5-14µm,
which is our standard filter window. Long range
pyrometers apply a sharp cut-on/cut-off window
of 9-14µm (G9) as per fig.2.
For the special application of Gas sensing by in-
frared absorption we offer narrow band filters to
detect specific gas absorption lines. The appropri-
ate narrow band optical filters enable detection of
Carbon Monoxide, Carbon Dioxide, Natural Gas
and other environmental gases, as well as some
technical gases.
A hot body of 2000 K emits a lot of energy, some
in the visible light range, some in the infrared (it
glows red or white-hot). A body of 500 K emits
radiation in the invisible part of the spectrum, the
infrared range, which we can feel, but not see.

Optical Properties
With respect to optical parameters of Detectors
and Sensors, there are some interesting items to
be mentioned: the optical bandwidth, transmission
and blocking characteristics of the optical filter
and, as major selection criteria, the sensor field of
view, and performance of the detector within the
field of view. The corresponding charts are given
for the various sensors and types.
In Fig.2 we show the graph for standard infrared
window and the pyrometric window “G9”. As to
narrow band Infrared filters, the range of available
filters and specifications is given in Table 1 below:

Pyroelectric Effect
Since ancient times the pyroelectric effect
has been known as a property of ferroelectric
materials. It is based on a specific behavior
of dielectric materials, the phenomenon of a
permanent electrical polarization. When
changing temperature of such materials, this
polarization will increase, or decrease, we
observe a charge displacement.
This pyroelectric effect is the basic principle
for detectors that can recognize temperature
variations. The characteristic value for the
permanent polarization, called pyroelectric
coefficient, disappears above the Curie point.
The Curie temperature limits the operation
temperature range for such detectors.
Pyroelectric detectors do not require cooling.
Detector Design
Within our detectors, a thin slice of pyroelectric
material is fitted with electrodes to form a
capacitor. Incoming radiation will generate
extremely low levels of thermal energy, so the
pyroelectric current flow is rather small. It needs
a circuit to convert this small current into a
convenient signal. The traditional analog
detectors apply a high ohmic resistor and a
special low-leakage current FET to transform
the high impedance of the detector material
to a common output resistance. The pyroelectric
element’s capacitance and the high gate
resistance of the FET form a RC circuit with
a time constant of approx. 1 s., which makes
the detector suitable for very low frequencies.
Detector Construction
The pyroelectric material is placed on a special
pc-board which provides thermal and mechanical
isolation for the delicate pyroelectric material and
provides space for the gate resistor and the FET.
The connections are made either by wire bonding
or conductive bonding. The whole pc-board is
placed on to a TO header and closed with a TO
cap, which has the relevant optical filter window.
The window possesses a special infrared trans-
mission characteristic, selected for the detector
application.
Pyro Characteristics
The most important electrical data of the IR-
Sensor are its responsivity, balance and noise.
Sometimes it is also useful to refer to NEP or D*.
Responsivity
The responsivity shows bandpass characteristics
with a maximum at approx. 0.1 Hz radiation
modulation. A typical curve „responsivity versus
frequency“ is indicated below as figure 5.
Responsivity is measured in V/W by means
of a defined black body radiator. Responsivity
refers to the active sensor area and is usually
tested at 1 Hz modulation frequency unless
specified differently.
Balance
The balance of a dual element detector indicates
the common mode rejection also called matching
between the two elements. It is an important
value for the performance of dual element
detectors, applied in motion applications, as it
is a measure for distinction between moving and
fixed objects. It can be specified either in V/W
or in % of Responsivity.
Noise
The noise of the sensor consists of three parts: The
basic thermal noise of the sensing material, the
(Johnson) noise of the high ohmic resistor and the
input noise of the FET. The total output of these
tree parts is rather stable for temperatures below
40°C. Above this temperature, noise increases
exponentially with temperature as can be observed
with typical active electronic components. Noise is
given in µV peak-to-peak or zero- peak. Similar to
the dependence of responsivity on frequency, the
noise values decrease with frequency from approx.
0.15 Hz to 50 Hz.
Pyroelectric Infrared Detectors
Excelitas is the first to having introduced digital
technology to Pyroelectric Detectors with it’s
DigiPyro® family. Here, a special ADC circuit
provides amplification, A/D conversion and
interfacing to the outside electronics.

Operating conditions
The storage and operating temperature range of
the detectors is specified from -40°C up to +85°C.
It needs to be noted that technical data usually
reference room temperature and may vary within
the specified temperature range.
Digital Pyrodetectors –
a New Family
Pyroelectric detectors are AC type devices and
give signals upon change of received Infrared
radiation. Until today, all available detectors are
analogue, i.e. they provide an analogue signal
output. Excelitas is the first to introduce a
family of detectors which differ from previous
generations by offering a digital signal output.
With the DigiPyro® family Excelitas is offering
digital Detectors for all these applications and
configurations.
1.1 Integrated Electronics
The DigiPyro® series integrates the first stages of
circuitry into the detector housing: Amplification
of the signal, then the A/D conversion, which
needs a voltage reference. Following an internal
10 Hz electrical low pass filter the serial Interface
provides for the “direct link“communication
which is a one wire bidirectional communication
feature. The whole concept is running by its own
internal oscillator, which determines the speed
of the internal process. The direct link feature
enables the user to have the host µC request
the information and its resolution, so the host
controls the communication speed.
1.2 From Analog to Digital
The DigiPyro series is the first pyroelectric detector
family to display information in Bit form as
opposed to µV signals of analogue detectors.
To give a measure for comparisons of traditional
detectors to digital versions, the rule of thumb for
signal levels versus bit information can be used:
• Resolution: 1 LSB 6.5 µV
• Noise: 6 Count 39 µV
(with band-pass)
• DC Offset 8192 Counts
• Digital Range: 0 to 16383 Counts
In a typical motion electronic application the
expected signal voltages range from 100 µV to
500 µV, so the digital signal may range about 100
bit-count on to the offset. The dynamic range of
the digital detector comprises the range from 511
counts to 15873 counts and with this it is wider
than the most application based signal levels.
Outside of this range the detectors offers an
Out-of-Range Reset function.
1.3 Digital Zero Signal Line
As the pyroelectric effect generates positive and
negative signal amplitudes, the detector circuitry
needs an electrical offset to be able to process
such signals. In all analog circuitry this value is
the offset voltage, which is usually subtracted
after the first amplifier stage.
With DigiPyros, the amplification is included
already, and the internal voltage reference
provides for the required offset. As to the user
this offset appears as a digital zero line at about
8000 bit-count, it may vary in series from one
part to the next. To recognize the zero line of
the individual detector, the user may either use
a digital band-pass or subtract the measured
offset from the signal.
1.4 The Host Needs to Filter The Signal
The DigiPyro does not include any processing
intelligence inside, unlike most analog
Pyrodetectors the DigiPyro uses a direct
communication with the hosting microcontroller
without any analog hardware filtering (only the
previously mentioned low-pass filter). Thus it
becomes necessary to implement all necessary
filtering by software filters within the hosting
microprocessor of the unit.
Applications
for Pyroelectric Detectors
Pyroelectric detectors had originally been
designed as single element types for non-contact
temperature measurement. During further
research, dual element types were developed
with multi-facet mirrors or Fresnel lenses entering
the field of motion detection, starting as passive
intrusion alarm (Burglar Alarm, PIR), followed by
automatic light switches and security lights and
lamps. The same concept is also applied with
some automatic door openers.
Today the Environment and its protection is
one of our most serious concerns. Features and
instrumentation are required to measure and
monitor all kinds of gas in our environment. One
of the methods applied is the NDIR technique, a
principle of measuring gas concentration by its
absorption properties in the infrared range. Our
detectors and sensors are a vital part of making
our environment more safe, secure and healthy.
Most of PIR Motion detecting devices have been
designed around Dual Element types, more
advanced units apply Four Element “Quad”
type configurations.
For Gas Sensing single element with narrow
band filters are applied in single or dual
channel configuration.
NEP, D*
The NEP value is a form of signal to noise ratio.
The NEP value specifies the minimum radiation
power that can be detected by the sensor, resulting
in an output that just exceeds the noise. NEP
refers to RMS values of signal and noise and in
addition to the electrical bandwidth. The lower
the NEP, the better the sensor is.
Sometimes also used for comparison of sensors,
the Specific Detectivity (D*) allows the character-
ization of sensing materials. It is defined as
reciprocal of NEP referring to the sensor area.
Details of these parameters as function of the
electrical frequency are given in Figure 6.

Thermopile Detectors and Sensors
A
B
U
The Seebeck Effect
Figure 7
The Thermoelectric Effect
The thermoelectric effect today is known as reverse
to the Peltier- (or Seebeck-) effect. By applying
a temperature difference to two junctions of two
dissimilar materials A and B, a voltage U which is
proportional to the temperature difference
is observed.
Leopoldo Nobili (1784 - 1835) first used the
thermoelectric effect for IR radiation measurement
using a “pile” of Bismuth and Antimony contacts.
The measure of this effect is called the thermo-
electric- or Seebeck- coefficient. For most
conducting materials this coefficient is rather
low, only few semiconductors possess rather high
coefficients. Since the voltage of a single thermo-
electric cell is very low, lots of such cells arranged
in a series connection achieve a larger signal,
making a “pile” of thermo-elements.
Excelitas Thermopile Design
Our thermopile sensors are based on the tech-
nology of Silicon Micromachining. The central
part of a silicon chip is removed by an etching
process, leaving on top only a 1 µm thin sandwich
layer (membrane) of SiO2/Si3N4, which has low
thermal conductivity. Onto this membrane thin
conductors of two different thermoelectric
materials (to form thermocouples) are deposited.
Both conductors have alternatively junctions in
the centre of the membrane (hot junctions) and
on the bulky part of the silicon substrate (cold
junctions). A special IR-absorption layer covers
the hot junctions creating the sensors sensitive
area.
When exposed to infrared radiation, the absorbed
energy leads to a temperature difference between
“hot“ and “cold“ contacts. According to the
thermoelectric coefficient of the thermocouples a
signal voltage is generated.
The Thermopile Construction
The sensor chip is mounted in good thermal contact
on to a TO header. A transistor cap with infrared
filter is sealing the sensor chip from
the environment.
Excelitas’s product portfolio includes detectors of
various sizes, housings and infrared windows, and
integrated sensors which include electronics that
provide temperature compensation and calibration
to a certain measurement range.
Excelitas offers unique constructions to deal with
the thermal shock, referenced as ISO-thermal types.
Advantages
Thermopile Detectors do not require any
mechanical chopper to sense infrared, thus
they offer simple design possibility to infrared
measurements.
Thermopile Characteristics
The most important properties of the Thermopile
Sensor are it’s responsivity, noise, field of view
response time, and for calibrated Sensors the
temperature range.
Responsivity
The responsivity shows low pass characteristics
with a cut off at approx. 30 Hz.
Responsivity is measured in Volt per Watt
by means of a defined black body radiator.
Responsivity data usually quote with respect
to the active detector area, and are given
without the infrared filter. The data show
a responsivity value, tested at 1 Hz
electrical frequency.
Noise
The noise of the detector is dominated by
the Johnson noise due to the resistance of
the thermopile. Noise is given as RMS value
in nV/Hz.
Sensitivity
The Data tables do also mention Sensitivity,
as a characteristic output voltage versus target
temperature at 25°C environment temperature.
The data are given with standard IR filter as
per fig.2. Two are given: S(25/40) is 25°C
environment, 40°C Black Body target and
S(25/100), which is 25°C environment, 100°C
Black Body target. Sensitivity is depending on
the field of view of the detector construction.
An example can be seen below for selected
TPS series:

Thermistor Is Included
As temperature reference the thermopile
detectors include a thermistor which senses
the internal temperature.
For exact measurements the temperature of the
detector housing (cold thermopile contacts)
must be known. As a standard version 100kOhm
thermistor inside the detector housing serves as
the ambient temperature reference, optional 30
kOhm is available.
The dependence of the resistance on temperature
can be approximated by the following equation:
RT NTC resistance in Ω at temperature T in K
RRNTC resistance in Ω at rated temperature

thermistor
eEuler number (e = 2.71828)
The actual characteristic of an NTC thermistor can
be roughly described by the exponential relation.
This approach, however, is only suitable for
describing a restricted range around the rated
temperature or resistance with sufficient accuracy.
For practical applications a more precise
description of the real R/T curve is required.
Either more complicated approaches (e.g.
the Steinhart-Hart equation) are used or the
resistance/temperature relation is given in
tabulated form.
The Field of View
The most common use of thermopile detectors
is non-contact temperature sensing. All target
points within the field of view will contribute to
the measurement signal. To meet requirements
of different applications, Excelitas offers a
broad range of sensors with different
windows and optics.
The field of view data describe the dependence
of signal from incident angles.
Temperature Range
Excelitas offers sensors which include pre-
amplification, ambient temperature
compensation and calibration within a
specific temperature range.
Thermopile Arrays
Further to it’s range of Detectors and Sensors,
Excelitas offers Line Arrays and spatial arrays
based on Thermopile technology.
Applications for Thermopile Sensors
Thermopile Sensors have been designed for non-
contact temperature measurement. The signal
of the sensor follows the radiation energy
receipt by the sensor. This enables the
application of measuring surface temperatures
without contact.
In many industrial process control units
thermopile sensors are used to contactless
monitor temperature or to serve as overheating
protection feature.
The thermopile technology is also suited for
domestic appliances such as food monitoring
during automated defrosting, warming-up
or cooking.
Same as our Pyrodetectors, the Thermopile
Detectors with specific filter windows are used
as sensing components making our environment
more safe, secure and healthy.

PYD 1798 offers better White-Light-Immunity (WLI) performance and Field of View. Both the
PYD 1788 and PYD1798 modelss include a built-in temperature reference. The Output signals
are communicated in one digital bit stream of 2x14 bit, output via a single wire “Direct Link”
connection to a suitable host microprocessor. With PYD 1784 we also offer an electrically

THERMOPILE DETECTORS FOR MEASUREMENT
Target Applications
•Non-contact Temperature measurements
•Thermometry
Features and Benefits
•TO type metal housing
•Optics included
•Thermistor included
Product Description
The -IRA type thermopile is specially suited with an internal reflector that reduces the field of view
and offers a smaller measurement “target” spot than conventional detectors without optics. Due
to the reflector, the housing size is taller than other types, although the housing has the same
diameter as a standard TO-5 housing.
The TPiD 1T 0226 L5.5 provides the ISOthermal performance feature and integral optics. A built

Product Description
Excelitas offers the proven concept of TPMI® in SMD housing. It senses the thermal radiation emitted
by objects and converts this to an analog voltage. The product is fully factory-calibrated for an accurate
signal output over a specified temperature range and includes optional temperature compensation. The
internal signal processing, with 8 bit resolution of the control registers and the EEPROM technology,
allows for calibration as per customer requirements.
A temperature reference output is included. Upon request, other object temperature ranges can
be provided. The sensors can also be supplied as “OBA“ version without internal temperature
compensation. By integrating the thermopile and electronic circuit into an industry-standard SMD
housing, the TPiS 1S 0133 enables fully-automated “pick and place” and soldering processes
associated with the SMD technology.
To address object temperature ranges, Excelitas offers the following standard pre-calibrated Sensors:
-20...60°C: TPiS 1S 0133 OAA060
-20...120°C: TPiS 1S 0133 OAA120
