Device for simultaneously viewing optical fibre ends from two mutually perpendicular viewing angles

摘要

The beams (1, 2) from the two viewing angles are guided by deflecting mirrors (U) in parallel onto a common magnifying optical system (V). The optical path lengths are matched by a plane-parallel glass plate (P) in one of the beam paths in such a way that the object planes for viewing from the two viewing angles seem to be located at the same distance.
