Gen 1, Gen 2, Gen 3, and Gen 4 Night Vision

Generations 1 through 4 of night vision refer to advancements in image intensification technology. Gen 1 uses basic infrared light amplification, producing low-quality images and limited range. Gen 2 offers improved brightness and clarity with a microchannel plate that amplifies light more efficiently. Gen 3 incorporates a gallium arsenide photocathode, providing better sensitivity, brighter images, and longer tube lifespan, suitable for military use. Gen 4, sometimes called "Enhanced" or "ARP," removes the ion barrier film found in Gen 3, resulting in even greater light amplification, improved image quality, and better performance in variable lighting. Each generation reflects progressive enhancements in image clarity, durability, and performance.
