ULTRA-SOL® OPTIQ PRO: Cerium oxide slurry

High-purity cerium oxide slurry for optical polishing

ULTRA-SOL® OPTIQ PRO is a high-purity cerium oxide slurry designed for the precision polishing of borosilicate glass, fused silica, glass ceramics, and other optical materials. OPTIQ PRO utilizes an enhanced manufacturing technique and features a small, tightly distributed cerium oxide particle in a unique suspension that minimizes settling and facilitates cleaning. In addition, the slurry is highly concentrated to provide maximum flexibility through on‑site dilution. It has quickly proven itself to be a superior cerium oxide polish to many existing products on the market.

ULTRA-SOL® OPTIQ PRO’s process performance exceeds industry specifications for sleek, scratch / dig, surface finish, and elimination of subsurface damage on precision glass workpieces. The unique chemistry allows for uniform and permanent suspension of the abrasive, which provides consistent and repeatable superior surface finishes, and ease of use in production environments.

Applications Fused silica, glass, zerodur

Highlights:
- Small particle size and tight distribution result in excellent surface quality, removal rate, and repeatability
- Suspension package facilitates uniform delivery of abrasive to polishing workpiece and prevents settling in the tools and lines
- Designed to be easy to clean off parts and tools, resulting in less rework and higher yields
- Compatible with polishing pads, pitch, CNC tools, and spindle polishers
