Can coated lenses be cleaned with ultrasonic waves?

Whether it is optical glass or spectacle lenses, they will be coated. From glazing material to finished product, coated lenses go through more than a dozen processes such as milling, fine grinding, polishing, and edge grinding. Ultrasonic cleaning can run through the entire lens processing process. It can be seen that the use of ultrasonic cleaning of coated lenses has unparalleled advantages over other cleaning methods in the large-scale production and processing of coated lenses, both in terms of cleaning efficiency and cleaning costs. It can improve the quantitative production and quality of coated lens products. play a positive role.

The process of ultrasonic cleaning of coated lenses includes the following steps:

1. Put the coated lens into the matching tooling and fix it in the cleaning basket

2. Place it in the ultrasonic cleaning machine tank and use 3-10% activation agent and clean water as the medium for cleaning. The ultrasonic frequency can be 60-120KHz;

3. Use 50-80℃ cleaning agent to rinse the active agent on the surface of the coated lens;

4. Use pure deionized water to ultrasonically rinse the coated lenses 3-5 times;

5. Place the coated lenses in pure water at a temperature of 30-60°C and rinse slowly at 10-50cm/min;

6. Place the coated lenses in a drying tank with deionized air, and dry them at a temperature of 30 to 60°C for 15 to 20 minutes.

The above process can solve the problems of particles and watermarks on the surface of coated lenses, improve the quality and yield of coated lenses, greatly improve cleaning efficiency, and adapt to the production and economic needs of the market.

Can coated lenses be cleaned with ultrasonic waves? Will it damage the lens coating? Ultrasonic cleaning technology combines the physical interaction and chemical reaction between the cleaning solution and the dirt attached to the surface of the coated lens, which can weaken the adhesion and binding force between the dirt and the surface of the coated lens, and ultimately achieve the purpose of removing dirt on the surface of the coated lens and make the coating The lens retains its original surface without damage. Therefore, coated lenses can be cleaned using ultrasonic waves without affecting the surface of the coated lenses.
