11.5: PROPERTY DATA TABLES

11.5 PROPERTY DATA TABLES

Property data for many optical materials are given in Tables 11.1 through 11.7. The tables contain physical, mechanical, thermal, and optical properties of selected optical materials. Materials selected for the data tables include both well-known, widely used, and relatively new substances. We have chosen to group similar materials together for ease of comparing potential candidates and conveniently accessing all properties for a given application. Much care has been exercised to ensure that the property data are for optical-grade material (fully dense, highly pure, and as close to intrinsic as possible) and that the property data are consistent and reasonable. Looking at the tables, one can see that there is wide variation in the quality and completeness of the property data. We emphasize optical properties and give appropriate formula constants and extensive references. Previous compilations of optical property data are given in Refs. 1 to 4, 11, and 12.
