The 640×512 medium-wave infrared detector converts infrared radiation in the 3.7μm-4.8μm band into voltage signals, featuring high performance, high resolution, low power consumption, compact size, and lightweight design. It serves as the core sensing component in infrared imaging subsystems for night vision systems, thermal imaging observation, forward-looking early warning, weapon guidance, air defense surveillance, and infrared recognition.
