Embodiment Construction

[0025] The "principal optical axis" in this application document refers to the straight line passing through the centers of the two spherical surfaces of the thin lens in geometric optics; Part of the beam; "aperture hole" should be understood as the optical space (shape) that constrains the light emitted from optical elements such as lenses or light sources to this "aperture hole" to obtain the beam we need for parts processing and other operations , it can be an unfilled through hole, or a light-transmitting hole filled with a transparent material, and the shape of the hole can be a circle or other polygons, such as a hexagon. Other words, words, and sentences in the application documents, if they are professional terms in the field of optics, are understood by the meaning specified in the industry terms (because the technical solution of the present invention is analyzed with geometric optics, so the corresponding professional terms are also preferably geometric Only when g...

Abstract

The embodiment of the invention discloses a diaphragm and a laser. Dust deposition of an optical system is prevented by arranging a dustproof mirror on a diaphragm base body, and meanwhile, an arc-shaped curved surface of the dustproof mirror is obliquely arranged, so that the adverse effect on the performance of the optical system caused by the arrangement of the dustproof mirror is greatly reduced. The diaphragm in the embodiment of the invention comprises a diaphragm base body and a dustproof mirror, wherein the available light emitting end of the diaphragm base body is provided with a diaphragm hole; the dustproof mirror is designed into an arc-shaped curved surface; the dustproof mirror is provided with a light-transmitting hole which is light-transmitting but is not through, and the light-transmitting hole is used for transmitting available light emitted from the diaphragm hole; and the dustproof mirror is fixed on the outer end face of the available light emitting end of the diaphragm base body.

Description

technical field [0001] Embodiments of the present invention provide an aperture and a laser, which relate to the field of optics, and in particular to optical elements in the field of optics. Background technique [0002] In the optical system, the diaphragm is often used to restrict the beam to obtain a better available beam, but during the use of the optical system, dust often falls through the diaphragm hole or end face hole of the diaphragm base to the optical components such as the lens or light source. superior. The dust falling on optical components such as lenses or light sources is more difficult to be cleaned in time due to reasons such as the structure of the optical system. [0003] The essence of dust is tiny particles of various substances. When light shines on dust, phenomena such as emission, diffuse reflection, and refraction will occur. Therefore, dust falling on optical components such as lenses or light sources will have a greater impact on the performa...
