The AN/PSQ-42 Enhanced Night Vision Goggle-Binocular (ENVG-B) is a third-generation passive binocular night vision device developed for the United States Army by L3Harris.It combines dual tube image-intensifying (I²) and thermal-imaging technologies into a single goggle, enabling vision in low-light conditions.
The AN/PVS-14 Monocular Night Vision Device (MNVD) is in widespread use by the United States Armed Forces as well as NATO allies around the world. [3] It uses a third generation image intensifier tube, and is primarily manufactured by Litton Industries (Now L-3 Warrior Systems) and Elbit Systems of America (formerly Harris Night Vision, formerly Exelis, formerly ITT [4]).

An image intensifier or image intensifier tube is a vacuum tube device for increasing the intensity of available light in an optical system to allow use under low-light conditions, such as at night, to facilitate visual imaging of low-light processes, such as fluorescence of materials in X-rays or gamma rays (X-ray image intensifier), or for conversion of non-visible light sources, such as ...
The AN/PVS-7 is a single tube biocular night vision device. Third-generation image intensifiers are able to be installed and are standard for military night vision. Most newer PVS-7 intensifier tubes are auto-gated to prevent image intensifier damage if exposed to intense light. The goggles have a built-in infrared Illuminator for low-light ...

The disadvantage to a thin or removed ion barrier is the overall decrease in tube life from a theoretical 20,000 h mean time to failure for standard Gen III type, to 15,000 h MTTF for thin film types. This loss is largely negated by the low number of image-intensifier tubes that reach 15,000 h of operation before requiring replacement.
The AN/PVS-17 is a Generation III Night Vision Device, and uses the OMNI IV MX 10160 3rd generation image intensifier tube, it can also be used as a handheld observation device. The designation AN/PVS translates to Army/Navy Portable Visual Search, according to Joint Electronics Type Designation System guidelines.
The device can be used for a further 7.5 hours in image intensifier mode. [ 9 ] Classified as a third-generation passive night vision device, the AN/PSQ-20 can provide vision through thermal imaging even in situations where there isn't enough ambient light for the image intensifiers, thus eliminating the need for infra-red illumination (active ...
