An improved baffle (24) for directing the light discharged from a deuterium lamp includes a plate-like member configured as a cylindrical segment (25), an aperture (27) provided through a central portion (26) of the member, and a flattened portion (26) about the aperture. The flattened portion is of such size and has a surface of such reflectivity as to substantially eliminate interference ring(s) of discontinuous light intensity from the light output of the lamp. A deuterium employing the improved baffle affords the advantage of markedly-increased light intensity, as compared with prior art baffles, at selected wavelengths. |
