Abstract:
1. A method for manufacturing a ceramic hybrid lens comprising: forming a ceramic lens using as a glass material a light transmitting ceramic having a particle diameter of 40 micrometers to on the order of 120 micrometers by grinding the ceramic to finish a surface of the lens such that the surface has formed thereon particle departure marks having a depth in a range from 50 micrometers to on the order of 60 micrometers; coating an ultraviolet curing resin to an aspherical mold and placing said surface of the ceramic lens on the resin so coated; forcing the ceramic lens against the mold and radiating an ultraviolet ray so as to cause the ultraviolet curing resin to cure; and thereafter, removing the ultraviolet curing resin cured together with the ceramic lens from the mold.
