ABSTRACT:
A glass faceplate having a central area of required useful diameter surrounded by a narrow ring of opaque glass and an outer glass mounting flange. Light entering the flange or ring is prevented from reaching the central area as stray light or glare in the system and spurious reflections at the interface of the ring and central area are minimized by a refractive index match of the two innermost glasses.
