The pvs-14 from the american agm global vision is a high quality night vision device with a gen.2 photonis commercial image intensifier tube in white phoshpor. Pvs residual light amplifiers, recognized worldwide for their unsurpassed quality, reliability and ergonomic design, were originally developed for use by the u.s. military. The agm pvs-14 is one of the best monocular night vision devices on the market. The pvs-14 has a 26mm lens with a wide field of view of 40 degrees and focuses from 25 cm. The optical magnification is 1x, but optical objectives with 3x or 5x magnification are optionally available. Image tube quality (iit) this version of the pvs-14 has a gen 2+ photonis commercial image tube in white phosphor (bright white/blue color that provides contrast like black and white). The tube has an average fom of 1300-1600. Fom stands for figure of merit and indicates the overall performance of a picture tube. The higher the fom, the higher the brightness and sharpness (and the lower the noise). Photonis tubes are among the best on the market and in no way compare in quality to your average gen 2+ tube. For this reason, you can work for a long time without infrared illumination, because the tube can convert even the smallest amount of residual light into razor-sharp visual images. This makes these devices very suitable for airsoft, tactical applications or mil-sim's. Cheaper, digital night vision devices always require you to use ir illuminators, which means that you are directly visible to your opponents/enemies. If you really need ir light (e.g. in a dark room with no residual light), then of course you can simply turn on the ir illuminator. This is located on the pvs-14. Helmet attachment and hands-free operation you can attach the pvs-14 to various helmet types via optionally available mounts. A head mounting kit (goggle kit) is also included with this product. This allows you to attach it to your head so that your hands are free. The goggle kit features a flip-up system that allows you to easily and securely flip up the night vision goggle and it will stay firmly in place. It has adjustable, comfortable head straps and a chin guard with built-in padding. Application agm pvs-14 white phosphor the agm pvs-14 is one of the best night vision devices on the market, making it an excellent choice for professionals and demanding enthusiasts. Think airsoft, tactical applications, hunting, survival or nature adventures. With the right accessories, you can attach the device to a helmet or use it hands-free with the included headset. Also included is a front screen that protects the lens from airsoft bullets, for example. This night vision device is equipped with a residual light amplifier tube, so you cannot use the device during the day. The device automatically turns off when there is too much light.
