PHYSICAL PROPERTIES OF COMMON OPTICAL MATERIALS

Listed below are several physical properties of some of the more commonly used optical materials. The B270 is most commonly used for simple lenses; BK7 for prisms and windows. Pyrex and Tempax are generally used as mirror substrates or wherever heat resistance and thermal stability are required. The various fused silicas are usually selected for thermal stability, heat resistance and spectral considerations.

The data shown below is of necessity limited in accuracy, completeness and consistency of presentation to what was available from the raw material manufacturers at time of printing. It is printed here merely as a convenience.
