ABSTRACT:
Two embodiments of an adjusting device for correcting misalignment in optical ray paths are disclosed. The first embodiment (FIGS. 1 and 3) has two transparent plane plates (21, 22) which are tilted relative to the optical axis and are supported with their mounts (35, 36) for rotation with constant angle of inclination around the optical axis in a tube (37) which is developed as an intermediate structure mountable in a desired location in an optical system. The second embodiment (FIGS. 2 and 5) has two wedge prisms which are displaceable with respect to each other along the optical axis and which can be turned jointly around the optical axis. Both embodiments are useful upon the coupling of a laser beam into a microscope in order to compensate for beam misalignment of the laser, the axis of which is subject to slow drift during operation.
