A line of ready to mix, high-purity calcined alumina powders for finishing precision optics that provide a lower cost alternative to diamond abrasives are available from Meller Optics, Inc. of Providence, Rhode Island.

Meller Microlux Aluminum Powders come in two grades and seven particle sizes from 0.05 to 3.0 microns and are ready to mix with de-ionized water for grinding, lapping, and polishing a variety of hard and soft precision optics. Capable of producing surface finishes to 10-5 scratch-dig, they are an effective alternative to diamond abrasives in many applications.

Meller Microlux Alumina Powders are offered in a Microlux-R version which features large agglomerated particles for aggressive grinding and lapping that break down under pressure for final polishing and are 99.98% pure. For fine grinding and uniform polishing, they offer a Microlux-RZ version with 99.99% pure de-agglomerated powders and controlled particle sizes.
