Abstract

An arc lamp with a housing including a base, an inert gas in the housing, a pair of spaced electrodes in the housing for establishing an arc in the gas to generate a radiation output, a window area on the housing for transmitting forward radiation generated by the arc, and an absorbing medium on the opposite side of the electrodes from the window for preventing backscatter radiation from the arc from passing through the arc and out of the window.
