Lamp Reflectors

The Main Reflector ensures that light from the Exposure Lamp exposes all areas of the
original. The Auxiliary Reflector reflects light onto the areas that the Exposure Lamp cannot
illuminate when an original that does not lie flat on the Original Glass (such as a book) is
being used. This reduces shadows which would otherwise be transferred to the copy.
The Main Reflector is of aluminum, while the Auxiliary Reflector is aluminum to which film
has been deposited. The same film as that used on the Auxiliary Reflector is affixed to both
ends of the frame to compensate for the reduced intensity of light around both ends of the
Exposure Lamp.
