Measurements of the thermo-optic coefficient of a barium fluoride single crystal.
The thermo-optic coefficient dn/dT of single-crystal barium fluoride is measured with a precision spectrometer. The values over the visible region in the 30-90 °C and 90-150 °C ranges are -18.8 and -19.7 × 10(-6)/°C, respectively.
