Laser marking method of infrared reticle

Abstract

The invention discloses a laser marking method of a reticle. The laser marking method comprises the following steps that S1, a to-be-marked pattern of an infrared reticle is drawn on a marking machine, horizontal lines and vertical lines which are cross uniformly are drawn in all graphs by which the to-be-marked pattern is formed to form reticular filling; S2, a horizontal marking graph layer is established for each graph, and marking parameters of the horizontal lines in all the graphs are set; S3, the to-be-marked pattern is copied and it is ensured that the copied to-be-marked pattern is completely overlapped with the original to-be-marked pattern, a vertical marking graph layer is established for each of the copied graphs, and marking parameters of the vertical lines in all the graphsare set; S4, the marking times of the horizontal mark graph layers and the vertical mark graph layers are set; and S5, the to-be-marked infrared reticle is placed on the marking machine, and marking is carried out according to the settings. According to the laser marking method, the operation is simple and convenient, the manufacturing period is short, the computer is adopted to control, automation is easy to realize, and the production efficiency of the reticle can be greatly improved.

Description

technical field [0001] The invention belongs to the field of reticle technology, and more specifically relates to a laser marking method for an infrared reticle. Background technique [0002] The infrared reticle is mainly used to check the parallelism between the optical axes of infrared thermal imaging cameras, low-light night vision devices, CCD TVs, and laser range finders. The infrared reticle adopts a metal hollow target plate, and the infrared reticle is heated by a thermal radiation source such as a black body, so that the reticle is imaged in the infrared optical system, and the infrared reticle in the optical system is controlled by the temperature of the black body. The brightness of the imaging is used to achieve the correction of the optical axis of the infrared optical system. [0003] The traditional infrared reticle is made by mechanical scoring, chemical corrosion or photocopying, which has a long manufacturing cycle and high manufacturing cost. Chemical so...
