Crystal Materials

Planar Grinding of Crystalline materials used in lens, viewing window, filter and substrate applications

DCM grinders outperform conventional surface grinders and often are the only economical solution for removing large amounts of material, while maintaining close tolerances and minimizing subsurface damage.

A DCM grinder is the efficient method for final sizing of vacuum chamber viewing windows, squaring boules to the crystal axis prior to sawing and coring or grinding the faces of prisms and optical filters.

Features such as variable feedrate & spindle speed, innovative mechanical design, and advanced abrasive technology make DCM grinders an ideal platform for processing materials such as Quartz, Fused Silica, Glass, Sapphire, Zinc Selenide, Zerodur, Silicon, and other crystalline materials.
