More Information about Infrared Sensors

Therefore, the effectively used wavelength range of an infrared sensor is only between (2 and 14) µm, with few exceptions. InfraTec’s infrared sensors are equipped with a special absorbent black layer and can therefore be used as extensive, stable, long-term receivers for UV radiation (for instance 193 nm), or with a special coating also for THz radiation in the range from 100 µm to 1 mm.

An IR Sensor for Low- and High-Temperature Applications

Depending on the basic physical principle, an IR sensor can either be applied in a wide temperature range without cooling (so-called thermal infrared sensors) or have to be cooled or thermally stabilised in order to achieve high resolutions (semiconductor resistors or diodes).

An InfraTec IR sensor is a thermal detector, which are ideally applied at temperatures of (-55 ... +105) °C. The lithium tantalate (LiTaO3) pyroelectric sensor element has a Curie temperature of 620 °C, which would allow for an even higher operating temperature. The temperature-limiting elements of the infrared detector are the infrared window and filter as well as the integrated, extremely noise- and stray-current-reduced preamplifier technology.

Detector Search

InfraTec offers five different product groups including approximately 50 standard pyroelectric detectors. Choose your suitable infrared detectors with the help of our detailed detector search.
