    摘要： Provided is an apparatus capable of producing a fluoride crystal in a very short period of time, and a method suitable for producing a fluoride crystal using the apparatus. The apparatus comprises a chamber, a window material, and the like, and is modified such that it can evacuate air from the chamber to provide a high degree vacuum there. The apparatus further includes a crucible, which has a perforation at its bottom. The capillary portion of the perforation is adjusted to facilitate the contact of a seed crystal with a melt. By using the apparatus it is possible to stably produce high quality single crystals of fluorides in a short period of time.

    摘要： It is aimed at providing an analysis method of impurities (color centers) in fluoride, capable of extremely simply analyzing impurities (color centers) in fluoride. It is also aimed at providing an analysis method of impurities (color centers) in fluoride, for enabling evaluation of an effect by addition of a scavenger, before obtainment of a final single crystal. There are detected absorption peaks and the like of formed color centers and the like, by irradiating X-rays to an obtained fused material, and by measuring transmittances thereof before and after the irradiation. Based thereon, there are optimized melt conditions of a scavenger and the like, thereby enabling growth of a high purity molten raw material suitable for growth of a single crystal less in X-ray damage.
