Do you know how to clean optical lenses effectively?

Optical lens cleaning process -- Cleaning pollutants -- YMMS Megasonic cleaning machine

In optical cold processing, lens cleaning mainly refers to the cleaning of polishing liquid, binder and protective material left after polishing. Clean the edging oil and glass powder after lens edging; Lens coating before fingerprint, mouth ring and various accessories cleaning. The traditional cleaning method is to use the wiping material (gauze, dust-free paper) with chemical reagents (gasoline, ethanol, acetone, ether) to soak, wipe and other means of manual cleaning. This method is time-consuming and laborious, poor cleanliness, obviously not suitable for the modern scale of optical cold processing industry. This has forced people to find a mechanized method of cleaning. Therefore, megasound cleaning technology gradually enters the optical cold processing industry, which will further promote the development of optical cold processing industry.

Megasonic cleaning is a cleaning technology that uses a transducer to send out megahertz high energy sound waves, and the solution molecules accelerate their movement under the push of the sound waves. The high speed hydrodynamics layer generated by the strong sound pressure gradient and the effect of sound flow makes the adsorption of fine particles desorption.

Megasonic cleaning will not produce strong cavitation effect, which can avoid the damage to the surface of the cleaning object and the residue of pollutants in the cleaning process. Megasonic cleaning has high efficiency, short time, low concentration of cleaning agent and less consumption of chemical reagents, so the level of harm to the environment is low.

‍‍‍Megasonic cleaning machine, cleaning uniform, fine damage is basically no, most suitable for semiconductor wafers and HDD parts of ultra-precision cleaning. Acceleration and chemistry are used to remove particles below the micron level. Various shapes of vibration plates can be set corresponding to different cleaning objects and devices. The material of the liquid connecting part corresponds to the cleaning fluid and cleanliness, using stainless steel - tantalum - quartz and other materials to make.‍‍‍
