Abstract
The color mixing compartment of illuminating equipment for a photographic enlarger includes two parts. The part adjacent the light-admitting surface is a truncated pyramid. The part adjacent the light-emerging surface is substantially a parallelepiped having side faces disposed substantially perpendicularly to the light-emerging surface. A diffusing plate having a substantially uniform thickness is arranged at the light-admitting and light-emerging surfaces of the mixing compartment.
Claims7
An illuminating apparatus for a photographic color enlarger comprising a color-mixing compartment having light-admitting and light-emerging surfaces, the color-mixing compartment having a first part disposed adjacent its light-admitting surface directly connected to a second part disposed adjacent its light-emerging surface, the first part having sides disposed at a substantial obtuse angle relative to the light-admitting surface in the form of a truncated pyramid, the second part having sides disposed substantially perpendicularly to the light-emerging surface substantially in the form of a parallelepiped head whereby a substantially uniform illumination of the light-emerging surface is obtained.
