Frequently Asked Questions

What are the advantages of a pyroelectric detector?

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).

What are the available IR windows that can be added to the TO can?

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 with a 10.6 µm peak).

What are the dimensions of the Gentec-EO Discrete Pyroelectric Sensor QS9-L?

The Gentec-EO Discrete Pyroelectric Sensor QS9-L has a diameter of 9 mm.

What is a pyroelectric detector?

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.

What is the maximum average power of the QS9-L sensor?

The maximum average power of the QS9-L sensor is 50 mW.
