Optical lens grinding technology is a method for manufacturing high-quality lenses, which mainly includes the following steps:
Material preparation: Select the appropriate optical material according to the use requirements of the lens, and cut the material block according to the design requirements. Ultra-pure water and cleaning agents are usually needed to ensure the material quality and surface cleanliness of the lens.
Grinding: Grinding is the core step in the lens manufacturing process. During the grinding process, it is necessary to place the material block on the grinding disc, add the grinding fluid, and then use different grinding tools and grinding discs to make the lens surface gradually smooth.
Polishing: After grinding, it needs to be polished to further improve the flatness and finish of the lens surface. Mirror polishing and electrolytic polishing are usually used to polish the lens.
Inspection: After grinding and polishing, the lens needs to be inspected. Common methods include optical interference method, Moore fringe method, coordinate measurement method, etc.
Coating: In order to improve the reflection and transmittance of the lens, it is usually necessary to coat the surface of the lens.
In general, optical lens grinding technology requires multiple steps to produce high-quality lenses, which requires high-level technology and experience.
