The study of calcium fluoride is of great scientific importance due to its wide scientific applications. Therefore, our study came to some of the physical properties of the compounds of both pure Calcium fluoride and indium doped Calcium fluoride. By measuring the infrared spectrum of pure Calcium fluoride, it is found that there are six vibratory frequencies, namely: (3444.52 – 1517.59 – 1138.40 – 876.40 – 639.93– 436.29) cm-1 and six vibratory frequencies for indium doped cal- cium fluoride at 3wt%. (3441.94 – 1516.77 – 1138.44 – 876.55 – 642.09– 436.44) cm-1 The study showed that the absorbance values, the absorption coefficient, the refractive index and the optical length were in the indium doped sample by 3wt% greater than that of the pure Calcium fluoride compound and are respectively: α=14.163 cm-1 , n=1.767.
