Exposure Lamp La1; Lamp Reflectors; Aperture Plates - Minolta EP1080 Service Manual

12-3. 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 sides of the frame to compensate for the
reduced intensity of light around both sides of the Exposure Lamp.
