Abstract
An apparatus for providing uniform light intensity is disclosed. The apparatus consists of a number of wires arranged diagonally and horizontally on a frame. The horizontal wires are arranged with variable vertical spacing to create eight different zones of light attenuation transmission. The apparatus is designed such that the zones having the highest light attenuation are placed in front of the most intense light from a source and the zones having the lowest light attenuation are placed in front of the least intense light from the source. By matching the zones of the apparatus to the intensity pattern of the light source a uniform light source is created.
