Cerium Oxide for Precision Optics
Precision optics covers a wide variety of glass types and processes. Demeter Technologies offers a wide selection of cerium oxide for precision optics powders and slurries which will meet your needs. Starting with custom designed raw materials, the particles are formed in a manner which produces consistent particle shape and hardness. Particle size reduction and classification is carried out to produce powders of very narrow particle size distribution which eliminates oversize particles which cause scratches and defects.
The benefits are:
- High polishing rates
- Defect–free surface finish
- Easy mixing and robust particle suspension
- Long slurry life
- Easy cleaning from all types of surfaces
- Low cost per finished unit
- No freezing restrictions
