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.
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.
