20090168433 | LENS FOR LIGHTING SYSTEM - A lighting system that produces a high intensity beam of light in the visible and infrared spectral regions that can be used for non-covert and ultra-covert operations. The lighting system is comprised of a HID lamp, a reflector, a lens, and a filter. The lamp utilizes a short arc gap and a unique combination of xenon gas, mercury and metal halides that produce a highly collimated beam of light in the visible and near-infrared regions. The reflector is a uniquely cut or cleaved and coated aluminum alloy that creates a highly reflective surface with minimal diffuse reflection and heat build up. The lens is coated on both sides with an antireflective coating that reflects ultraviolet light and enhances the transmission of visible and infrared light. The lens is also coated on its outer surface with a hydroscopic material that protects the glass lens and the second antireflective coating from abrasion while facilitating the dispersion of water on the outer surface. The filter is formed of a red glass substrate with a multi-layer dichroic coating on the inner surface of the filter, which is effective at blocking visible light while allowing a high percentage of infrared light to be transmitted. The combination of the lamp, reflector, lens and filter results in an ultra covert night vision illuminator system that closely matches the radiant sensitivity of Generation III night vision systems. | 07-02-2009 |
