Abstract
A reflector includes a plurality of cylindrical bands having reflective outer surfaces and arranged about a common axis. The bands are sized and spaced such that, when mounted in front of a convergent beam spotlight, they prevent the rays of light from converging at a point so as to generate an intense heat which could damage a filter material, for example.
