Thermal Imaging

Pyroelectric single-element and multi-channel infrared detectors from Heimann Sensor are designed for usage in spectroscopy, pyrometry and security engineering applications. Very high values of specific detectivity D* in the range of 10 9 cm Hz 1/2 W -1are 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 moderate and large quantities with excellent price-performance ratio

Single Detectors

Our pyroelectric single sensors are based on lithium tantalate and show a very high sensitivity of up to 10 9 cm Hz 1/2 W -1. Round and square elements are available with diameters or sides as listed below:


  •    0.5 mm
  •    1 mm
  •    2 mm
  •    3 mm

Dual and Quad Detectors

Sensors with two, three or four different spectral channels are available. The channels can be equipped with either Heimann Sensor standard optical filters or customized infrared filters according to a customer specification. The two- and three-channel sensors are also offered with thermal compensation.

    Linear Arrays

    Heimann Sensor’s 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 a 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.
