摘要

The device has a casing with a base plate (11), two edge units (16, 17), three supporting units (12-14), a side cover (19) and a cover plate (18). Two prisms (P1, P2) are movably installed in the casing in a compact and lateral manner. The prisms consist of glass or transparent synthetic material and exhibit a base surface of right-angled triangle. The base plate and the cover plate are arranged parallel to each other in the casing.
