New laser diode optical path shaping mechanism with adjustment function

Abstract

The invention discloses a new laser diode optical path shaping mechanism with an adjustment function. The optical path design comprises a laser diode and a lens set. The lens set is composed of a collimating lens, a first plano-convex cylindrical lens, a second plano-convex cylindrical lens and a double convex cylindrical lens. At the same time, the invention adopts a guide rail, an adjustment slider, a lens holder and a light source fixing seat. In actual use, the light source is fixed on the light source fixing seat, and the lens is fixedly mounted on the lens fixing seat. The light source fixing seat is fixed on one end of the guide rail. The lens fixing seat is fixed on the adjusting slider. The adjusting slider is slidingly matched with the sliding groove of the guide rail, and the side of the guiding rail is provided with a scale. The entire set of experimental equipment can fully demonstrate the effect of laser shaping, and can accurately adjust the relative position between thelens sets to explore the optical path shaping design.

Description

technical field [0001] The invention relates to the technical field related to optical engineering, in particular to a novel laser diode optical path shaping mechanism with an adjustment function. Background technique [0002] In the past few decades, the application occasions of laser technology have continued to increase and become more and more mature, and more and more products using the principle of laser technology have entered our lives. According to different needs, the laser emitted by different lasers needs to be shaped accordingly. The three-dimensional laser scanning technology uses the principle of laser measurement to scan the surface of the measured object through a line of laser light to obtain a large amount of surface information data, which can quickly reconstruct the measured object. The 3D model of the target and various map data such as lines, surfaces, and volumes. Compared with the traditional single-point measurement, the 3D laser scanning system ca...

Problems solved by technology

The laser quality of traditional inline lasers meets the requirements of use and the volume is generally large, which limits the miniaturization of the scanner structure to a certain extent. The miniaturization of product structure is an important trend in laser application products. The light source includes shaping optical path The size of the laser diode is an important factor affecting the volume of this type of product. The existing laser shaping has the problems of poor optical path versatility and difficult adjustment. Therefore, we propose a new laser diode optical path shaping mechanism with adjustment function to solve the problem. above question
