Our recent high-resolution interferometric investigations on 4He solid/superfluid interfaces have revealed interesting static and dynamic phenomena in quantum crystals. In this work we have initiated studies of 3He crystals and developed a new optical setup which combines two interferometric principles with different resolutions. Our setup allows determination of overall crystal shapes as well as high-resolution studies of facets down to millikelvin temperatures.
