The Special Operations Peculiar MODification (SOPMOD) kit is an accessory system for the M4A1 carbine, CQBR, FN SCAR Mk 16/17, HK416 and other weapons used by United States Special Operations Command (USSOCOM) special forces units, though it is not specific to SOCOM.
The first ACOG model, known as the TA01, was released in 1987. [3] [4] An example was tested on the Stoner 93 in the early 1990s by the Royal Thai Armed Forces. [5]In 1995, United States Special Operations Command selected the 4×32 TA01 as the official scope for the M4 carbine and purchased 12,000 units from Trijicon. [6]
The sight is designed for use on small arms in the U.S. military's inventory, but it can also be used as a standalone observation device. The AN/PAS-13B uses thermal imaging so that it can be used day or night. Thermal imaging also allows the sight to see through smoke or fog, things that may normally obscure other night vision devices.
The effect on the natural night vision of the eye is evident A standard telescopic sight augmented with a night-vision device in front on the M110. Note that in addition to the image intensifier, the NVD gathers much more light by its much larger aperture A 1PN51-2 night-vision reticle with markings for range estimation First-person view ...
The ZG 1229 Vampir was a Generation 0 active infrared night vision device developed for the Wehrmacht for the StG 44 assault rifle, intended primarily for night use. The issuing of the ZG 1229 Vampir system to the military started in 1944 and it was used on a small scale in combat from February 1945 until the final stages of World War II.

Digital night vision relies on high sensitivity back-illuminated CMOS image sensors, also sometimes called sCMOS (scientific CMOS). Their sensitivity can exceed the sensitivity of the human eye. [13] These sensors can be head-mounted in night vision goggles and rifle scopes, but are also used in security camera systems, astronomy, and ...
The optical window in a holographic weapon sight looks like a piece of clear glass with an illuminated reticle in the middle. The aiming reticle can be an infinitely small dot whose perceived size is given by the acuity of the eye. For someone with 20/20 vision, it is about 1 minute of arc (0.3 mrad). [citation needed]
