Intrinsic birefringence in single crystals of CuBr has been measured in the vicinity of the absorption edge at 300 K. The strong enhancement of the birefringence in the direction \(\vec q\) //[110] near the gap is caused by the spatial dispersion of the dielectric function. An attempt is made to deduce band-parameters from the experimental data.
