A full line of optical polishing pitch that comes in five hardness grades and can be easily mixed for precisely lapping virtually any optical mater-ial is available from Meller Optics, Inc. of Providence, Rhode Island.

Gugolz Optical Polishing Pitch from Meller Optics comes in five grades from very-soft to very-hard with melting points from 52°C to 87°C, and is ready to use without screening, filtering, or mixing additives.
