11-3. Lamp Reflectors
The Main Reflector ensures that light from Exposure Lamp LA1 exposes all areas of the
original. The Auxiliary Reflector functions to reflect light onto the areas that LA1 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.
