Filed:
Dec 26, 1979
Appl. No.:

Inventors:

Abstract:
The disclosure describes an enclosed area (19) between a beamsplinter (11) and a curved reflective surface (12), two end surfaces (20) and (21) and a top membrane (22). The space (19) is hermetically tight and encloses a suitable dry gas, such as nitrogen. With a device constructed in this manner positioned adjacent a suitable television tube, such as CRT (17), the device will function as is well known, but cleaning and damage to optically coated surfaces is eliminated completely.
