Outdoor enthusiasts have been able to buy the civilian version of the equipment that has revolutionized warfare, but it can be expensive. What's known as ``Generation 3'' night-vision equipment can cost $1,500 and up. Earlier generations cost less but don't perform as well. Traditional night-vision scopes use image intensifiers and photocathode Noun 1. photocathode - a cathode that emits electrons when illuminated cathode - a negatively charged electrode that is the source of electrons entering an electrical device tubes to convert light into electrons, which are projected on a phosphor A rare earth material used to coat the inside face of a CRT. When struck by an electron beam, the phosphor emits a visible light for a few milliseconds. In color displays, red, green and blue phosphor dots are grouped as a cluster.

Bushnell - maker of binoculars, telescopes, spotting scopes, riflescopes and other outdoor gear - has developed a compact night vision viewer using technology similar to that in digital cameras. The Bushnell NightHawk nighthawk: see goatsucker. nighthawk Any of several species of North and South American birds in the whippoorwill family (Caprimulgidae) that are buff, reddish, or grayish brown, usually with light spots or patches, and 6–14 in. viewer eliminates the image intensifiers and photocathode tubes. The key element in the new viewer is the charged-coupled device (CCD CCD in full charge-coupled device Semiconductor device in which the individual semiconductor components are connected so that the electrical charge at the output of one device provides the input to the next device. ), which gathers the light and converts it to electronic information. After processing, the image is displayed on a viewing screen on the back of the unit at 200-percent optical magnification. Unlike the old technology, the NightHawk viewer can be used in daylight without damaging the device and images appear in black and white, not shades of green Shades of Green is a United States Department of Defense-owned resort located at Walt Disney World in Lake Buena Vista, Florida. It is an Armed Forces Recreation Center (AFRC) resort and therefore a part of the military's Morale, Welfare, and Recreation program (MWR). . Jordan Vermillion, product manager for Bushnell, said the device, which looks like a compact digital camera, is designed for backpackers, hikers, hunters and others who want to observe wildlife at night. Hunters who want to go to their tree stand without using light will like the swivel screen design which makes it easy to use the device for walking at night. The NightHawk has excellent resolution, comparable to Generation 2 or 3 devices that cost much more. The sensitivity is not as great as these devices, but Bushnell is working on that. Built in LED, infrared illuminators allow users to see 50 to 60 feet in total darkness. The suggested retail price for the NightHawk night vision viewer is $199.99. Vermillion said that Bushnell is developing a night vision device that will capture images. ``We own the night,'' says the U.S. Army. But now everyone can buy a piece of it. |
