Abstract
A Bausch and Lomb spherical lamp housing is converted into an ultraviolet lamp for illuminating biological material. The original bayonet socket is replaced by an admedium socket into which is placed an AH-4 100 watt mercury vapor lamp. This lamp is operated with a G. E. Auto-transformer No. 59G22. The visible light is filtered out by Corning glass u.-v. light filters. When a greater amt. of u.-v. light is needed, the lamp housing reflector is aluminized, and the condensers are replaced by quartz condensers. The microscope condenser is replaced by one of quartz and the mirror is aluminized. For fluorescent microscopy, it is necessary to place in the ocular a Corning glass u.-v. light absorption filter.
