NIGHT VISION BUSHNELL MONOCULAR
Night Vision Bushnell products feature a built-in infrared illuminator for enhanced images in very low light for use when camping, exploring caves, patrolling warehouses or other locations where there is no ambient light to amplify. Backed by a 2-year limited warranty, the Bushnell line-up of night vision equipment is lightweight, compact and ready to use for work or for play.
Compact, lightweight monocular offers outstanding clarity in the darkest conditions.
Objective Lens
Collects all available light and focuses it on the image intensifier. It also provides image magnification. The best objective lenses have low magnification (5x or less), are high-speed (f2 or faster) and are coated for maximum efficiency in the near-infrared bandwidth.
Phosphor Screen
Positioned at the back of the intensifier tube, the green phosphor screen renders a visible Night Vision image. The human eye is most sensitive to green contrasts.
Photocathode
Converts light (photon energy) into electrons (electrical energy), which are then amplified in the intensifier. The objective lens focuses available light on the photo-electric surface of the photocathode, which is excited and passes electrons within the tube.
Resolution
A measure of the ability to render and display a detailed image. Imageintensifier resolution remains constant and is expressed as the maximum number of line pairs per millimeter (lp/mm) that can be discerned when a black-and-white stripe pattern is focused on the photocathode.
