Meller Optics’ Microlux alumina abrasive powders grind, lap and produce a superior finish on optics at a lower cost than diamond abrasives, the company says.
According to the company, the abrasives can produce surface finishes to 10-5 scratch-dig on calcium fluoride, ferrites, germanium, silicon, stain-less steel, zinc selenide and zinc sulfide. They feature seven particle sizes ranging from 0.05 to 3.0 microns.
The powders are available in two grades: Microlux-R for aggressive grinding and lapping, which has large agglomerated particles that break down under pressure for final polishing, and Microlux-RZ which has controlled particle sizes for fine grinding and uniform polishing.
