Samarth Security Systems manufactures Night Vision Binoculars and Monocular. Samarth Security Systems is ISO 9001: 2000 certified company that offers all types of metal detectors and visual search devices. The Night Vision Binoculars and Monocular consist of several main parts, an objective lens, an eyepiece, a power supply and an image intensifier tube [Photocathode Tube]. Night vision devices gather existing ambient light [starlight, moonlight or infra-red light] through the front lens. This light, which is made up of photons goes into a photocathode tube that changes the photons to electrons. The electrons are then amplified to a much greater number through an electrical and chemical process. The electrons are then hurled against a phosphorus screen that changes the amplified electrons back into visible light that you see through the eyepiece.
