Abstract

See full text

A prism assembly includes a first prism, a second prism, a roof prism and an optical multilayer film. The first prism includes a first, a second and a third surface. The second prism includes a fourth, a fifth and a sixth surface. The fifth surface faces the third surface. The roof prism includes a seventh, an eighth and a ridge surface. The seventh surface faces the second surface. The optical multilayer film is disposed between the fifth surface and the third surface. A first light beam and a second light beam entering the first prism are totally reflected from the second surface to the optical multilayer film which reflects the first light beam but allows the second light beam to pass through. The second light beam enters the second prism, is totally reflected on the sixth surface, and exits from the fourth surface of the second prism.
