    摘要: A short wavelength light emitting element such as an ultraviolet light emitting element or a blue light emitting element is disposed in a container having a window fitted with a window plate formed from calcium fluoride crystal. Thus, there can be obtained a light emitting element device of high reliability. Use is made of a fluoride crystal containing either one or both of a metal and a metal halide. Such a fluoride crystal is produced through a process comprising filling the cavity of a crucible with raw powder and heating the crucible in the vertical Bridgman furnace, wherein the cavity of the crucible has a section of reduced shortest diameter. There is also provided a crucible used for producing the fluoride crystal which has a cavity to be filled with raw powder and is heated in the vertical Bridgman furnace, wherein the cavity has a section of reduced shortest diameter.
