Adjusting device converting circular beam into elliptical beam

Abstract

The invention discloses an adjusting device converting a circular beam into an elliptical beam. The adjusting device comprises an optical part and a mechanical part, one end of an optical fiber is used for connecting optical fiber heads, a first plano-convex lens and a plano-concave cylindrical mirror are installed in an cavity of the optical fiber joint at intervals, the end cover and the fixingsleeve tube sleeve the head of the optical fiber joint, a threaded sleeve tube sleeves the fixing sleeve tube, and the threaded sleeve tube and the optical fiber joint are connected through a T-shapedthread which penetrates through the fixing sleeve tube; a plano-convex cylindrical mirror and a second plano-convex lens are installed in a cavity of an adjusting sleeve tube at intervals, a plano-concave lens is installed in a cavity of a plano-concave lens seat, and the other end of the adjusting sleeve tube is in threaded connection with the plano-concave lens seat. The device has the advantages that the circular beam output by a laser device can be rapidly converted into the elliptical beam, the overall adjustment is simple, the implementation is easy, the production cost can be effectively reduced, the production efficiency can be effectively improved, processing demands on objects of different shapes can be achieved, and the processing quality level is greatly improved.

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,...
