The 66944-500H-R07 Mercury Light Source is a complete plug and play light source system that includes a 500 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 high performance 4-element Aspherab™ lens with a F/# of F/0.7. This lens configuration provides the highest quality output light. Four different lenses are used in a unique configuration to provide light output that is nearly free from spherical aberration.
