The manufacturing process of optical glass involves several critical steps, with grinding and cleaning being two of the most important. After grinding, the surface quality and appearance of the lens are determined. Common contaminants include abrasive powders, such as cerium oxide, and asphalt, which acts as a protective layer during polishing. Some processes may also introduce paint flakes. The choice of grinding powder depends on the lens material and required precision. Cleaning after grinding typically uses either organic solvents or semi-aqueous agents to ensure optimal results.
Before coating, lenses must be thoroughly cleaned to remove core oil, fingerprints, and dust. This step is crucial, as even the slightest contamination can affect the final product’s quality. Selecting the right cleaning agent is essential—not only for its effectiveness but also for its safety and compatibility with the lens material.
Ultrasonic cleaners operate at different frequencies, each suited for specific applications. Low-frequency cleaners (20–30 kHz) are ideal for heavy-duty or large workpieces, while higher frequencies (above 40 kHz) are used for delicate parts where minimal surface damage is required. High-frequency systems enhance cleaning performance by increasing cavitation bubbles, allowing them to reach smaller spaces without damaging the surface. These bubbles create shock waves that dislodge dirt effectively.
Another key factor in ultrasonic cleaning is the straight-flow effect, which occurs when sound waves move through the liquid. At around 0.5 W/cm², this flow becomes visible, stirring the surface and enhancing the cleaning process. It helps mix the cleaning solution, accelerating the dissolution of contaminants.
For higher frequency systems, the cavitation effect is less pronounced, so the cleaning action relies more on the acceleration of liquid particles. This method ensures ultra-precision cleaning without harming the object’s surface.
