This Gen 3 NV monocular is flat out incredible! Some real minor blemishes on the exterior, but the lens and tube are in super shape (would rate the tube at 97% and the housing at 90%.) Hate to sell, but funding another NV/Thermal project and it's just been sitting in the safe. Sold new, Gen 3 units like these run about $3,000+. $1600 shipped USPS Priority within USA. Will consider trades. Always interested in quality optics. Definitely interested in Kimber (Yonkers) Klassic or SuperAmerica .22lr ITT Industries Night Vision, the world’s leading producer of eneration (Gen) 3 image intensification devices, offers the highest performance image intensifier tubes available. ITT’s Gen 3 F9800 Series (MX-10160) image intensifier tubes are designed for use in all night vision systems that use an inverting tube, such as aviators’ goggles, ground binoculars, and weaponsights. ITT offers a selection of tubes, with ifferent performance levels, to satisfy a wide range of ustomer specifications. This selection includes ITT's innacleTM technology which surpasses the performance of all other Gen 3 tubes previously and currently fielded. Description: ITT’s F9800 Series Gen 3 18-mm image intensifier consists of a high-efficiency GaAs photocathode bonded to a glass input window, a microchannel plate (MCP) current amplifier, and a P-43 phosphor screen deposited on an inverting fiber-optic output window. The Gen 3 photocathode is very sensitive to lowradiation levels of visible and, especially, near infrared light. It also provides very high signal-to-noise ratio (SNR) for extended detection ranges at very low light levels. The 6-micron channel spacing in ITT’s MCP provides exceptional resolution. The MCP has a thin ion-barrier film that preserves photocathode sensitivity during operation, thereby greatly extending the life of Gen 3 tubes compared to Gen 2. ITT continues to improve Gen 3 MX-10160 image intensifier tubes to increase operational range and situational awareness for the user. Equipped with a gated power supply, the Pinnacle versions provide truly outstanding performances in high-light or lightpolluted areas, such as such as urban environments. In addition, the Pinnacle tube provides a much reduced halo.
