Problems solved by technology

[0003] Lens is one of the most important optical components in imaging equipment, such as cameras, projectors and video cameras, etc., and lenses are all essential components. However, since lenses are directly exposed to the air, in actual use, the lens It is one of the parts that are most likely to be defaced, and the defacement of the lens directly leads to the loss of accuracy when the equipment is used, so the lens must be cleaned for positioning, but at present, the cleaning of the lens is only a simple The processing and cleaning steps and processes are not standardized, and the cleaning aids used are also relatively corrosive. Therefore, long-term use will cause damage to the lens and cause secondary damage. Therefore, obtaining a systematic lens cleaning method is Technology that is urgently needed at this stage

Embodiment 1

[0019] A non-destructive cleaning method for an optical lens, comprising the following preparation steps:

[0020] 1) Take out the lens that needs to be cleaned from the optical equipment, and then perform preliminary floating dust cleaning. When cleaning, use a hair dryer to blow off the floating dust on the surface of the lens with cold air;

[0021] 2) Place the above-mentioned lens after cleaning the floating dust on the platform, then use a sprayer to spray both sides of the lens wet, and then let it stand for 15 minutes;

[0022] 3) After the lens treatment in the above step 2) is completed, use a brush to initially scrub the surface. When scrubbing, rinse with warm water at a temperature of 35°C while scrubbing. The scrubbing time is controlled at 7 minutes;

[0023] The above-mentioned hair brush is a silicone brush;

[0024] 4) After the scrubbing in the above step 3), take a soaking tank, add alcohol into the tank, add all the scrubbed lenses into it, soak for 40 mi...

Embodiment 2

[0030] A non-destructive cleaning method for an optical lens, comprising the following preparation steps:

[0031] 1) Take out the lens that needs to be cleaned from the optical equipment, and then perform preliminary floating dust cleaning. When cleaning, use a hair dryer to blow off the floating dust on the surface of the lens with cold air;

[0032] 2) Place the above-mentioned lens after cleaning the floating dust on the platform, then use a sprayer to spray both sides of the lens wet, and then let it stand for 10 minutes;

[0033] 3) After the lens treatment in the above step 2) is completed, use a brush to initially scrub the surface. When scrubbing, rinse with warm water at a temperature of 25°C while scrubbing. The scrubbing time is controlled at 5 minutes;

[0034] The above-mentioned hair brush is a silicone brush;

[0035] 4) After the scrubbing in the above step 3), take a soaking tank, add alcohol into the tank, add all the scrubbed lenses into it, soak for 30 mi...

Abstract

The invention discloses a nondestructive cleaning method for an optical lens and relates to the technical field of optical lens treatment. The method includes the steps that the component is taken down, floating dust is cleaned off, surface stains are brushed off, cold and hot water treatment is carried out, alcohol is used for disinfection and sterilization, soaking is carried out with auxiliaries, and then drying is carried out. The method has the advantages that the technology process is simple; by systematic treatment on the lens, it is guaranteed that the surface of the lens will not be damaged; meanwhile, clearing and cleaning are standard and reasonable, and the cleaning effect is remarkable; meanwhile, the actual light transmittance of the lens can be improved, toxin and corrosion are avoided, and application and popularization are convenient.

Description

technical field [0001] The invention relates to the technical field of processing optical lenses, in particular to a non-destructive cleaning method for optical lenses. Background technique [0002] A lens is an optical device that receives an optical object on a camera and adjusts it to achieve optical imaging. A lens is usually a lens group composed of one or more pieces of optical glass, and the basic unit is a concave lens, a convex lens, or a combination thereof. Modern camera lenses also use aspheric mirrors, which are divided into optical glass ground aspheric mirrors and plastic pressed aspheric mirrors. Under the condition that the imaging quality is basically the same, the manufacturing cost and service life are quite different. In theory, a simple convex lens is a lens, but in practical applications, the lens requires a combination of various lenses to correct optical distortion. [0003] Lens is one of the most important optical components in imaging equipment...
