Newport MKS Mercury Light Source, 200 W, F/2.2 Asphere, Research Housing 66479-200H-R22

The 66479-200H-R22 Mercury Light Source is a complete plug and play light source system that includes a 200 W Hg arc lamp, lamp socket adapter, research light source housing, lamp power supply, and all the necessary interconnection cables for operation. The provided 69910 arc lamp power supply is a highly regulated for maximum stability. Much of an arc lamp's stability in wavelength and output intensity is due to keeping the temperature and pressure of the gas inside the lamp's envelope as constant possible. The included Oriel Research Arc Lamp Housing offers a built-in ignitor board and rear reflector for optimum lamp performance. A built-in cooling fan maintains a safe operating temperature for the lamp. The user is protected from accidental exposure to UV radiation and electrical shock by the lamp housing's safety interlock, which disables ignition and power to the lamp if the housing door or lamp housing interconnection cable is not securely connected. The condenser lens assembly included with this light source uses a single aspheric lens with an F/# of F/2.2. The front surface of an aspheric lens gradually changes in curvature from the center of the lens to the edge. This shape reduces spherical aberration more effectively than a plano-convex lens.
