Differences between VOx and a-Si technology

Differences between VOx and a-Si technology

Infrared focal plane array is the core of infrared thermal image system.It can be widely usedin security monitoring, industry, transportation,medical and other fields. Currently, VOx and a-Si are the main sensitive materials of uncooled infrared foca
Can infrared rays penetrate wall and glass?

Can infrared rays penetrate wall and glass?

In nature, objects above absolute zero (-273.15 C) can emit infrared radiation. Sinceinfrared rays areinvisible light, infrared detectorsrely on the temperature difference between the target and its background to identify objects. If the temperature
Difference between uncooled and cooled infrared detectors

Difference between uncooled and cooled infrared detectors

Infrared detectors can be divided into uncooled infrared detectors and cooled infrared detectors according to their different working principles. This articlewill introduce the differences between the two in termsof working principle, sensitive mater
The composition of infrared thermal camera

The composition of infrared thermal camera

Infrared thermal imaging is a detection technology which identifiesthe temperature distribution of the object. It converts light signalsinto electrical signals through the infrared detector, and then converts them into a thermal image after processin
Differences between MWIR & LWIR cooled infrared detectors

Differences between MWIR & LWIR cooled infrared detectors

At present, the most commonly used cooled infrared detectors are MWIR and LWIR. They are divided based on the detected response wavelength and therefore differ in some respects. When customers choose a cooled infrared detector, they often think about
Infrared optical lens

Infrared optical lens

Infrared optical lens is a critical configuration of the infrared optical system, which directly affects the performance of infrared camera. Infraredlens collects infrared radiation actively emitted by the target and focuses it on aninfrared detector
