DATA SHEETCUTTING STOCK FOR DOUBLY ROTATED BLANKS This document provides typical specifications for single crystal cultured quartz material grown on a Z-plate seedthickness shear mode. The additional rotation is about the Z-axis and is designed to reduce the effects of stresson resonant frequency.Sawyer ResearchD-Bars are lumbered such that doubly rotated blanks are easily obtained when the D-Bar iswafered using procedures similar to those used to fabricate AT-cut blanks. The for IT-cuts, is provided by Sawyer Research, as shown.
