Cleaning for Dirt on the Surface of the Filters
With the rapid development of high technology in our country, filters have become common in our daily lives, but many people do not understand how to deal with dirty lenses. Hanzhong Borisun Optics Co.,Ltd is a professional manufacturer of filter lenses. Let me analyze it for you! Cleaning process for the surface of filter lenses.
1、 Ultrasonic Cleaning
Ultrasonic cleaning is simple and fast, suitable for large-scale use of filter lenses. Insert the lens into the fixed bracket, put it in ultrasonic water, and shake for 15 to 30 minutes.
2、 Ha Qi Fa
If the lens is dirty, blow air onto the dirty surface of the lens and then wipe it with a dust-free cloth.
3、 Alcohol Wiping Method
Pour a small amount of ethanol onto the dirty glass surface, and use a clean, dust-free wiping cloth to wipe the lens surface from left to right and top to bottom. If it is still dirty, try again until there is no more dirt.. (Note: Do not wipe back and forth, as it will become dirtier and have a counterproductive effect.)
The three methods mentioned above are the simple cleaning methods for optical filter glass summarized by the editor.
Solvent Cleaning
Common solvents include aqueous solutions (acid or alkali solutions, detergent aqueous solutions, etc.); Anhydrous solvents (ethanol, acetone, emulsions, etc.). The type of solvent is usually selected based on the properties of pollutants on the glass surface.
Scrubbing and Soaking
The simplest scrubbing method is to use degreasing cotton, lens paper, rubber rollers or brushes dipped in water, alcohol, cleaning powder, chalk, etc. to wipe the glass surface. When scrubbing, it is necessary to prevent the glass from being scratched, and at the same time, the residual cleaning powder and chalk on the surface should be washed away with pure water and ethanol.
Another common method is to soak and clean the glass in a container containing a solvent. After soaking for a certain period of time, use tweezers or other special fixtures to remove the cleaned glass and dry it with a pure cotton cloth. This method requires simple equipment, easy operation, and low cost.
