Abstract

Measured data are presented on glass transition temperature, thermal expansion coefficient, and refractive index for glasses in the Ge–As–Se system. The range of reciprocal dispersive power between 8 μm and 12 μm of 110–159 for these glasses is discussed in relation to their basic physical properties, and it is shown that useful compositions for bulk synthesis can be identified. A brief account is given of the preparation techniques, which enable glass to be made with an oxide content of the order of 1 ppm wt as measured by gamma photon activation analysis. The influence of oxide impurity on the transmission is shown for the three glasses Ge20–Se80, As40–Se60, and Ge30–As15–Se55.
