Medium wave infrared photodetector

VIGO Poland is a professional company that produces infrared detectors and preamplifier circuits. The infrared detectors produced by the company are divided into two categories: cooled (low-temperature operation) and uncooled (room temperature operation), with more than 70 models, including antimony cadmium mercury (MCT) long wave andMedium wave infrared photodetector， III-V group materials (InAs, InAsSb) infrared detector. VIGO also produces and provides preamplifier modules and refrigeration controllers corresponding to detectors.

The Polish VIGO infrared detector complies with the ISO9000 international standard quality system and is widely used in gas detection in environmental protection, as well as in research and development fields such as infrared detection and monitoring, radiation temperature measurement, laser tracking and positioning, laser warning, laser recognition, metrology, and optical communication.

PVI-2TE-5Medium wave infrared photodetectorBy using a two-stage semiconductor cooling system with an immersion lens, the incident light can be effectively enhanced. During crystal production, the wavelength response of 4 microns was optimized, with peak response wavelengths ranging from 3 to 3.5 microns. The detector is equipped with a 3-degree anti-interference wedge angle protection window, which can effectively reduce the interference noise of coherent light such as laser. The reverse bias function can be used to improve the response speed and dynamic range of the detector.

Damage threshold:PVI-2TE-4Detector, for continuous light or width exceeding1The microsecond illumination is:2.5W/cm2Pulse width less than1The microsecond pulse light is:10kMW/cm2.Exposure to light exceeding the damage threshold can cause irreversible damage to the detector, and should be strictly avoided during use.
