Laser light barrier plate

Abstract

The invention discloses a laser light barrier plate which comprises a light barrier plate body, a laser light through hole, an adjusting plate and a cooling circulation system. The middle of the light barrier plate body is provided with the laser light through hole and the adjusting plate, the light barrier plate body is fixed to an optical table through fixing screws installed on a base, the laser light through hole is a long light through hole, the adjusting plate is fixed to the light barrier plate body through a fixing screw, the adjusting plate is adjusted and fixed through a long adjusting hole and the fixing screw, light through holes of different sizes are formed between the laser light through hole the adjusting plate through the action of the adjusting hole and the fixing screw, and a water channel, an inlet in the water channel and an outlet in the water channel of the cooling circulation system are formed in the periphery of the laser light through hole and inside the light barrier plate body. In this way, the laser light barrier plate can adjust the laser light through hole according to the size of a laser light beam, and the unnecessary laser light beams can be blocked and absorbed through the adjustment of the light barrier plate for a plurality of laser light beams.

Description

technical field [0001] The invention relates to the field of light baffles, in particular to a laser light baffle. Background technique [0002] The general light baffle is a metal light baffle with a fixed light hole in the middle. When the size of the laser beam changes, it is not easy to make corresponding changes to this light baffle; Adjustment of the number of multiple laser beams passing through; and the general light baffle is not equipped with a cooling cycle system. For the laser light path that has been continuously working for a long time, the light baffle will cause sudden accidents in the light path due to overheating. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a laser light baffle, which uses a thick metal plate as a light baffle to block the laser beam; the size of the light hole can be adjusted through the function of the adjustment plate; cool down. [0004] In order to solve the above t...
