Pyroelectric Sensors
In General
The pyroelectric single-element and
multi-channel infrared detectors from
Heimann Sensor are designed for use in gas
analysis, spectroscopy, pyrometry and
security engineering applications.Very high values of specific detectivity D* are achieved by using modern ion beam etching technology for extremely thin elements. The great variety of infrared sensor constructions makes it possible to realize custom-made solutions for both small and large quantities with an excellent price-performance payoff. Pyroelectric SensorsSingle Sensors
Our pyroelectric sensors, based on lithium
tantalate, are distinguished by a very high
detectivity. Advanced ion beam etching is
used to prepare sensors with specific
detectivity values up to 109 cm Hz1/2W-1.
These sensors are suited for various
applications such as gas analysis,
IR-spectrometry, remote temperature
measurement and security systems. The
following sizes and shapes of the responsive
element are possible:
Available Types:
Pyroelectric SensorsQuads and Duals
Different absorbing layers are used to
create high and uniform sensitivity over a
broad spectral range. Sensors with 2, 3 or 4
different spectral channels are available.
The channels can be equipped with either
Heimann Sensor standard optical filters or
customized infrared filters according to a
given specification. The 2 and 3 channel
sensors are also offered with additional
blinded elements for thermal compensation.
Pyroelectric SensorsLinear Arrays
The Heimann Sensor pyroelectric linear
arrays are hybrid detectors with 128 or 256
responsive lithium tantalate elements and a
multiplexing read out integrated circuit.
The 128 element linear array has a pitch of
100 µm and element sizes of 90 µm x 100 µm,
90 µm x 500 µm or 90 µm x 1000 µm. The 256
element linear array has 50 µm pitch and an
element size of 42 µm x 100 µm. The
pyroelectric chip and the read-out circuit
are arranged in a metal hermetic package
with an infrared window that determines the
spectral sensitivity.  More
