Problems solved by technology

[0002] At present, there are many types of filters, and the requirements for each band are different. Some require coating processing to achieve the desired effect. Different bands require different processing times. Some bands require longer processing time and high cost consumption.
[0003] In order to achieve the purpose of the filter to completely absorb the 400nm-700nm part of visible light, the general treatment process is to realize the absorption of visible light by the filter through the coating process. The production efficiency of the original coating process is 7H / 120pcs. Moreover, different optical filters need different coating treatments, which leads to low production efficiency.

Embodiment 1

[0034] Such as figure 1 As shown, a filter coating method uses coating technology to achieve the purpose of complete absorption of the visible light 400nm-700nm part, and the infrared part has a high transmittance effect, saving coating processing time and reducing costs.

[0035] Specifically include the following steps:

[0036] Step 1: put the lens to be coated into the sample stage;

[0037] Specifically, spin coating equipment is used to coat the surface of the lens before production. First, before the lens to be coated is put into the sample stage, the filter tip of 0.45um ~ 0.8um is used to filter the liquid, that is, the infrared absorption The mixture coating liquid is filtered.

[0038] Then, put the lens to be coated into the sample stage, put it into the rotary chuck of the sample stage, and use the vacuum pump to absorb the lens to be coated on the sample stage.

[0039] Step 2: drip medicinal liquid in the glass tube above the sample stage;

Abstract

The invention discloses an optical filter coating method. The method comprises steps of placing lens needing to be coated on a sample table; dropping liquid medicine into the glass tube above the sample table; dripping the liquid medicine onto the surface of the lens; uniformly attaching the liquid medicine to the surface of the lens; and putting the coated lens into a nitrogen oven to be baked. According to the optical filter, the traditional coating processing is replaced by the coating technology, so that the aim of completely absorbing the visible light part of 400-700nm by the optical filter is achieved, the infrared part has a high-transmittance effect, the processing efficiency is improved, and the cost is reduced.
