Stiff optical element polishing material

Classical polishing process

Information

It can be used for polishing optical spherical glass and plane glass with abrasion degree below 100, such as quartz glass, fused quartz glass, etc; Used in classical polishing process.


(1) Large particles: the particles are evenly distributed and D50 > 1.5 μ m. It has the characteristics of fast cutting force and is suitable for optical materials with hard materials.
(2) No impurities: adopt multiple processes to screen and remove impurities to ensure that the product is free from scratches after use.
(3) Easy to clean: by controlling the particle shape and adding additives, the surface of the product is easy to clean after use.
