640×512 MWIR FPA Detector Module

Overview

The 640×512 MWIR FPA detector module (hereinafter referred to as the "detector module") has the function of converting infrared radiation signals in 3~5u m wave band into electrical signals. All mechanical, optical and electrical interfaces are of universality, and can be used in various military and civilian thermal imaging systems such as various night vision equipment, panoramic searching, thermal image sighting, forward looking warning, weapon guidance, air defense monitoring, infrared recognition, infrared diagnostic testing and temperature measurement.
