REPEATING DEVICE OF CHANGING PROGRESSIVE PATH OF LIGHT

摘要

PURPOSE:To make the change in the progressing direction of light easy by connecting a photodector and a light radiator by means of an optical fiber and constituting these to one body. CONSTITUTION:The light which is made incident to a photodetector from an objective lens 1 thereof is condensed with lenses 2, 3, and is emitted through an optical fiber 6 to the outside from the lenses 13, 12, 11 of a light radiator. The progressing direction of the light is easily changed by curving the fiber 6.
