Baffle plate with plated film

Abstract

A baffle plate with plated film includes: a first baffle plate and a second baffle plate. A plurality of through holes are provided on the first baffle plate. The second baffle plate Includes a plurality of interconnected shield units matched with the plurality of through holes. The second baffle plate can move relative to the first baffle plate so that the plurality of shield units respectively cover the plurality of through holes of the first baffle plate, or a preset distance is provided between the first and second baffle plates.

Description

technical field [0001] The invention relates to a baffle, in particular to an optical coating baffle. Background technique [0002] With the development of optical products, the scope of application of optical lenses is becoming wider and wider. Correspondingly, the industry adopts various methods to manufacture optical lenses to meet the market demand for optical lenses of different specifications (see "Fabrication of Diffractive Optical Lens for Beam splitting Using LIGA Process", Jauh Jung Yang; Mechatronics and Automation, Proceedings of the 2006 IEEE International Conference on, pp.1242-1247, 2006.06). At the same time, in order to reduce costs and improve efficiency, mass production is carried out to meet the demand for optical lenses. Generally speaking, the manufactured optical lenses need to undergo subsequent processing to obtain good properties suitable for the application. [0003] The coating process is one of the important steps in the subsequent processing....

AI Technical Summary

Problems solved by technology

However, the existing baffles are generally driven manually or mechanically, which requires a certain reaction time

Moreover, the existing baffles cannot control the output of the film material during the coating process to make the coating more uniform
