An assembly and alignment method for an electro-optical device and a measuring device assembled and aligned according to the method

摘要

The method involves fixing a semiconductor laser (102) in a printed circuit board (108) in a position, and fixing a collimation lens (104) in a collimator holder (110) in another position. The collimator holder is connected with a mounting plate (124), and the mounting plate is positioned and fixed relative to the printed circuit board through an adhesive process by using light-hardened adhesive material. An axial distance between the collimation lens and the semiconductor laser is adjusted through the relative position of the holder. An independent claim is also included for a measuring device comprising an optical transmitter.
