Optical Surface Polishing

Nanophase optical surface polishing slurries offer more consistent polishing than other commercially available slurries. Our proprietary plasma process produces highly dense and fully stable nanoparticles that don't break down during polishing. Not only do they produce the same results each time they are used, but the slurry does not need to be topped off as is required with most commercial slurries.

Nanophase Cerium Oxide and Aluminum Oxide improve upon the fundamental performance requirements of optical surface polishing slurries across the board: improved flatness and roughness, faster time to surface finish and improved surface quality. In addition, the use of Nanophase slurries leads to reduced waste and defectivity and improvies ROI no matter what material you are polishing.

Our slurries will also expand your capabilities, allowing you to meet more rigorous specs in an increasingly demanding industry.
