Frequently Asked Questions

What are the advantages of a pyroelectric detector over other IR detectors?

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 different families of products to choose from?

There are four families of products to choose from: QS-L (discrete pyro detectors, low noise level), QS-H (discrete pyro detectors, high average power), QS-IF (hybrid pyro detectors, current mode, fast response), and QS-IL (hybrid pyro detectors, current mode, low noise level).

What are the physical characteristics of the QS3-H pyroelectric sensor?

The physical characteristics of the QS3-H pyroelectric sensor include a maximum average power of 500 mW, spectral range of 0.1 - 1000 μm, current responsivity of 0.25 μA/W, thermal frequency of 5 Hz, temperature coefficient of 0.2 %/°C, aperture diameter of 3 mm, absorber MT, dimensions of 9.1Ø x 6.4D mm, weight of 0.001 kg, and package TO5.

What is a pyroelectric detector?

A pyroelectric detector is a thermal detector that produces a current output that is directly proportional to the rate of change of temperature when exposed to a source of radiation.

What is the QS3-H pyroelectric sensor used for?

The QS3-H pyroelectric sensor is ideal for pulsed laser applications, thermal measurements, laser optics, metrology, inspection, and biomedical and military applications.
