Lamp reflector assembly
The reflector of the lamp has three major parts. One mounting plate, one spheric glass mirror and one elliptic glass mirror. Both
mirrors are glued on the mounting plate and are perfectly aligned with each other. The mounting plate serves also as a reference
plate between the reflector and the projector optics. The mounting plate has two positioning pins which ensure a correct alignment
of the reflector assembly with respect to the projector once the lamp house is inserted in the projector.
