Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] Such as figure 1 As shown, the infrared two-dimensional scanning mirror group of the present invention mainly consists of six lenses, and the six lenses are sequentially arranged as the first lens L1, the second lens L2, the third lens L3, and the fourth lens according to the incident light direction of the laser light. Lens L4, fifth lens L5, sixth lens L6.

[0023] Wherein, the second lens L2 is a meniscus lens, and the curved surface is curved towar...

Abstract

The present invention provides an infrared two-dimensional scanning mirror group, including the first, second, third, fourth, fifth, and sixth lenses arranged in sequence in the incident direction of infrared laser, wherein the first lens is double-concave lens, the second lens is a meniscus lens, and the curved surface is bent toward the incident direction of the light, the third lens and the fifth lens are double-convex glass, the fourth lens is a plano-concave lens, and the sixth lens is a protective glass; The lens group is used for infrared lasers with an entrance pupil diameter of 30mm, a focal length of 275mm, and a wavelength of 1064nm. The processing range is 130mm*130mm processing area. The light spot of the infrared two-dimensional scanning mirror group of the present invention can meet a certain requirement in a certain area, so when there is a certain defocus, the processing quality will not be affected, the processing effect can be guaranteed, and the actual use requirements can be met.

Description

technical field [0001] The invention relates to an infrared two-dimensional scanning mirror group, in particular to an infrared two-dimensional scanning mirror group whose light spots in a certain area meet certain requirements. Background technique [0002] With the continuous development of laser processing technology, the types of media that need to be processed are increasing day by day, and the effect of processing is required to be more and more refined. The use of ultrashort pulse laser for laser processing is becoming more and more widespread. Some processed media are very fragile, cracks are prone to occur during processing, and the requirements for edge quality and edge angle are also very high. Ultrashort pulse laser with infrared wavelength can meet such processing requirements. Its processing heat The impact area is small, so it is widely used in ultra-fine marking, special material cutting and cutting. [0003] In the application field of laser cutting process...
