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