Diaphragm and laser

Abstract

On the basis of any one embodiment, the embodiment of the invention further provides a laser which can comprise a light source circuit, a laser base and the diaphragm in any one embodiment. The diaphragm is installed on the laser base, the specific connection mode can be detachable connection or non-detachable connection, and the specific connection mode is not limited. A containing space for containing a light source circuit is arranged in the laser base in an extending mode, and the specific shape of the laser base can be reasonably arranged according to requirements and is not limited. A light source circuit of the laser is used for generating laser with a preset wavelength in a preset laser propagation direction. The specific implementation mode of the light source circuit is mature in the prior art, and is not described herein. According to the technical scheme, the embodiment is only used for explaining the technical scheme of the invention instead of limiting the technical scheme; although detailed description is carried out on the method by referring to the embodiment, ordinary technicians in the field should understand that the technical schemes recorded in the embodiments can still be modified or part of the technical characteristics can be equivalently replaced; the modification or replacement does not make the essence of the corresponding technical scheme break away from the spirit and range of the technical scheme of each embodiment of the invention.

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 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 impact on the performance...
