An adjustment device for converting a circular beam into an elliptical beam

Abstract

The invention discloses an adjustment device for converting a circular light beam into an elliptical light beam. It includes an optical part and a mechanical part, one end of the optical fiber connector is used to connect the fiber head, the first plano-convex lens and the plano-concave cylindrical mirror are installed in the cavity of the optical fiber connector at intervals, and the end cap and the fixing sleeve are sleeved on the Outside the optical fiber connector, the threaded sleeve is placed outside the fixed sleeve, and the threaded sleeve and the optical fiber connector are connected through a T-shaped thread passing through the fixed sleeve; the plano-convex cylindrical mirror and the second plano-convex lens The plano-concave lens is installed in the cavity of the plano-concave lens holder at intervals, and the other end of the adjustment sleeve is threadedly connected with the plano-concave lens seat. The invention can quickly convert the circular beam output by the laser into an elliptical beam; the overall adjustment is simple and easy, and can effectively improve production cost and production efficiency; it can realize processing requirements for objects of different shapes, and greatly improves the processing quality level.

Description

technical field [0001] The invention belongs to the technical field of laser applications, and in particular relates to an adjustment device for converting a circular beam into an elliptical beam. Background technique [0002] Laser is another major human development since the 20th century, following atomic energy, computers, and semiconductors. Laser is a new light source in the 1960s, which has the characteristics of good directionality, high brightness, good monochromaticity and high energy density. The laser industry based on lasers is developing rapidly in the world, and has been widely used in industrial production, communication, information processing, medical and health, military, cultural education, and scientific research. Among them, in the industrial production of laser, the processing objects of different shapes and the final processing quality level of the objects need to be completed by using light spots of different shapes, sizes and densities. At present,...
