BEAN-SPLITTING PRISM,METHOD OF MANUFACTURING SAID OF PRISM

摘要

The prism has an entrance surface for a radiation beam, a beam- splitting surface and an exit surface for a radiation beam which has been deviated inside the prism. The entrance and exit surfaces form part of prismatic glass elements. A roof-edge prism has a refractive edge arranged on the exit surface. The roof-edge prism is formed from a transparent, curable liquid synthetic material which is deposited on the exit surface and cured in situ after the refractive edge is formed by a die in the liquid material. The roof-edge prism is made of a synthetic material which cures under the influence of ultraviolet radiation.
