Title: OPTICAL MEMBER AND PROCESS FOR PRODUCING SAME
Abstract:
An optical member produced from a ceramic in which transparency in each wavelength region can be selectively improved, and a process for producing the optical member. The optical member is obtained by bringing a treatment gas comprising a fluorine atom into contact with an optical material comprising a specific ceramic under conditions according to the specific ceramic to thereby form a fluorinated film capable of improving the transmittance of light having wavelengths in a specific region, on at least some of the surface of the optical material.
