A hi end nightvision binoculars are an optical instruments that enhance light on dusk situations using image intensifier unit. Night vision devices most often are used by the law enforcement personnel or soldiers, but are available also to civilian market for hunters, wildlife and astronomy enthusiasts and so on. NVG – night vision device consists from image intensifier unit, a rugged and in most cases waterproof housing, and some type of mounting system. Many of devices also include interchangeable frontal objectives, diode or laser infrared illuminators, and lenses with different magnification.

Night vision devices found their first use in World War II, and came into general use by military during the Vietnam War. The technology has enhance greatly since first devices available, leading to several image intensifiers “generations” of night vision equipment with each time performance increasing and price decreasing. this links are here to help chose right night vision device and provide general info on night vision.

Infrared thermography, this hi end flir systems, thermographic imaging, or thermal video, is a type of infrared imaging science. Thermographic cameras detect thermal radiation in the infrared range of the electromagnetic spectrum (roughly 900–14,000 nanometers or 0.9–14 µm) and produce images of that radiation, called thermograms. This systems can be used in variety of different tasks like border surveillance, maritime, commercial security, military.

There are loads of other tasks for a thermal image, which time by time are really life-saving. Even firefighters at their tasks are using a thermal image to locate possible victims in full of smoke areas. Search and Rescue agencies try to find people with the help of a thermal image. Any application that needs to see in total darkness, through smoke can benefit from the power of a flir systems.
