摘要： Phosphate or flurorophosphate glass surfaces are polished to smooth, highly accurate surfaces using a glass polishing liquid having a pH approximating the pH of the glass being polished. A highly polished glass surface results suitable for use optical filters and solid camera devices and solid image sensors. Phosphate and fluorophosphate glass filters and the like so formed have hair-like surface flaws, if any, of a width of 7 .mu.m or less.

摘要： Glass surfaces are produced having a highly polished surface by polishing with a glass polishing liquid having a pH approximating the pH of the glass being polished. The method provides highly polished, smooth, highly accurate glass surfaces suitable for use optical filters and solid camera devices and solid image sensors. Phosphate and fluorophosphate glass filters and the like so formed have hair-like surface flaws, if any, of a width of 7 &mgr;m or less.
