The ENVG-B uses L3Harris' proprietary SuperGain image-intensification tubes, claimed to provide better image gain and brightness than previous Generation 3 image intensifier tubes. [8] The ENVG-B can also display wirelessly transmitted weapon sight crosshair and thermal imagery from the Family of Weapon Sights-Individual (FWS-I) thermal imager ...
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]). [5]
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 ...
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-4 uses a 25mm screw-type variable-gain Image Intensifier tube. Operational voltage is 3.0 Volts. Early production models feature two circular battery compartments located on the main housing. These battery compartments are designed to accommodate one 3.0V BA-5567/U, or two 1.5V BA-3058/U simultaneously.
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 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/PSQ-20 Enhanced Night Vision Goggle combines image intensifier (I 2 or II) and infra-red (IR, also called thermal imaging) technologies, and is the first night vision device to do so. Before this "fusing", these two technologies could only be used separately.
