1、Performance and Characteristics
※ The crystal grains are fine and uniform, with good suspension.
 
2、The Scope of Application
※ High precision requires optical spherical surface, flat lens, final polishing of high-quality ultra-precision optical components.
※ It is suitable for grinding of spherical surfaces. The polishing effect of plane mirror is also relatively good. The scope of application is wide, and higher polishing effect can be obtained at lower concentration. The improvement of lens finish is very obvious, and excellent aperture stability can be obtained.
