Abstract
A compact multiflash unit that contains a plurality of flashlamps, which mounted on a base member along with reflector members, is provided with a protective plastic cover having light-controlling prisms molded into its side walls. The prisms are so oriented and profiled that they serve as integral optical elements which direct the light rays from the 'fired' lamps toward the scene being photographed, thereby compensating for the lateral spreading of the light rays produced by the shortened reflector members.
