Abstract
{110} surfaces of CaF2 crystals are etched with different concentrations of HCl. It is found that concentrated HCl produces characteristic rectangular pyramidal etch pits and 2 volume percent HCl produces boat shaped etch pits. Such variations in the etch pit shapes on {110} surfaces of CaF2 crystals with different concentrations of HCl have been explained. Concentrated H2SO4 is found to be a suitable chemical polisher for these surfaces, the polishing rate is about 0·1μ/min.
