Abstract

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, meanwhile, the side surface of the dustproof mirror is obliquely arranged, and the adverse effect on the performance of the optical system due to the arrangement of the dustproof mirror is greatly reduced. The diaphragm provided by the embodiment of the invention comprises a diaphragm base body and a dustproof mirror, wherein he dustproof mirror is provided with a light-transmitting and non-through diaphragm hole, and other parts, except for the diaphragm hole, on the dustproof mirror are light-proof parts; the dustproof mirror is arranged to be an inclined plane with the vertical plane of the main optical axis as the horizontal reference; and the dustproof mirror is arranged on the end face of the available light emitting end of the diaphragm base body.

Description

technical field [0001] Embodiments of the present application provide an aperture and a laser, which relate to the field of optics, and in particular to optical elements in the field of optics except lenses. 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. On the other hand, the dust falling on optical components such as lenses or light sources is difficult to be cleaned in time due to the structure of the optical system and other reasons. [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 i...
