The birefringence of the mixed crystal Zn0.14Cd0.86S has been measured near its isotropic point and found to be highly dispersive. The region of strong dispersion shifts to shorter wavelengths than observed in pure CdS, and its magnitude near the isotropic point is larger. These results are highly significant for the development of narrowband dispersive birefringent filters in the blue-green region of the spectrum.
