9. Table of Recommended Glasses

On the following pages you will find a cross-reference guide comparing glass types from OHARA and Schott.

Cross Reference Chart of Recommended Glasses
Code:	Along with OHARA's glass type designation, the technical data sheets will show the six-digit code for each glass type. In the six-digit code (in bold type) the first three decimal digits represent the refractive index at the helium line () and the last three digits represent the Abbe number (). This six-digit code is internationally recognized within the optical community.
Glass Type:	We have shown OHARA recommended glass types and corresponding glass types from Schott.
