摘要

The measurement of the temperature coefficient of the refractive index of optical glasses using the schlieren method is presented. The heat propagation in two plane-parallel plates made from different optical glasses, with the same geometry and identically heated, is simultaneously investigated using the schlieren setup. One of the plates with known parameters describing the heat diffusion and the temperature coefficient of the refractive index provides the calibration of the experimental configuration. The theoretical model of heat diffusion, experimentally checked by us [1], allowes the determination of the unknown temperature coefficient of the refractive index for another plate. The experimental results are in good agreement with the values found in the literature.
