In 1960s, theUnited States,Britain,FranceandGermany, Holland and other countries, and the successful development of the LLL night vision, and the sight form on the rifle and light machine guns and other light weapons. Around 1996, using by fiber optical panel coupled to the cascade type electrostatic focusing as intensifier of first generation LLL night vision sight into the battlefield use. In early 70, using the multi alkali photocathode and micro channel plate image intensifier second low-light-level sight application. Such as AN/TVS - 5 type, 9 degree field of view, magnification 6.2#+[*], the starlight night vision distance of about 1000m. In the early 1980s, theUnited Statesand developed into escrow, the NEA photocathodes (III ~ V photoelectric cathode or negative electron affinity photocathode). The typical product is MK500 type multi-purpose optical sight, which can be installed two can hold three escrow, escrow.
