Light transmitting coupling system - uses immersion in liq. of known refractive index to compensate unevenness of ground surface

摘要

Light transmitting system coupling by means of immersion and refractive index of immersion differs from that of optically effective system parts. A system is used n which one or more of the surfaces bonded by the immersion are uneven. The optically effective system parts have this unevenness which corresponds to a coarsely or a finely ground surface. The light beam (6) appears on the boundary surface (1-3) of an angle of incidence (11). The broken beam (7) emerges at an angle (12) which is obtained from the refractive indices of the boundary media.
