Frequently Asked Questions
The advantages of a pyroelectric detector over other IR detectors are room temperature operation, broad spectral response, high sensitivity (D*) and fast response (sub-nsec into 50 Ω).
The available IR windows that can be added to the TO can are Quartz: 0.2 – 3.5 µm, Barium fluoride: 0.2 – 17.5 µm, Sapphire: 0.1 – 7.0 µm, Silicon: 1.2 – 9.0 µm and 22 – 100 µm, and AR germanium: 1.8 – 23 µm (10.6 µm peak).
The Gentec-EO Discrete Pyroelectric Sensor QS3-L is 9.1Ø x 6.4D mm in dimensions.
A pyroelectric detector is a thermal detector that produces a current output proportional to the rate of change of temperature when exposed to a source of radiation.
The maximum average power of the QS3-L sensor is 50 mW.
