APPARATUS FOR JOINING AN OPTICAL FIBRE AND A PHOTODETECTOR, AND METHOD OF POSITIONING THESE

摘要

A base member formed as a right dehedron has first and second surfaces on which are respectively secured a plate bearing a photodetector and a platelet bearing an optical fiber end. The position of the fiber endface with respect to a photosensitive surface of the photodetector is checked using an optical magnifier means to observe a spot of a white light beam emitted by the fiber end onto the photosensitive surface. The spot must be concentric with the outline of the photosensitive surface.
