A confocal scanning laser microscope operating at 514 and 488 nm has been used to obtain two‐dimensional (2‐D) images of the mercuric bromide (HgBr 2 ) crystal surface by photoluminescence, reflection, and transmission phenomena. Our measurements indicate that regions showing a strong photoluminescence may appear on the surface. By processing the 2‐D images, we obtained the three‐dimensional images, which offer a better possibility for the investigation. The analysis of spectral lines may be correlated with the presence of the Hg impurities.
