A concentration series of fluorite crystals Ca1–xSrxF2 (0 ≤ x ≤ 1) has been grown by directional crystallization according to the Bridgman technique. Experimental (weakly quadratic) concentration dependences of the lattice parameter a(x) and density ρ(x) are obtained for the Ca1 – xSrxF2 (0 ≤ x ≤ 1) solid solution. A calibration density curve ρ(x), which is suitable for non-destructive testing of the composition of optical elements made of Ca1 – xSrxF2 crystals with an error of Δх = ± 0.001, was constructed.
