Patent ID: 7431984

Claim:
A hybrid lens comprising: a lens base of translucent ceramic containing as a main component, an oxide with a perovskite structure represented by A{M ,( B 1, B 2)} O 3 wherein A is at least one member selected from the group consisting of Ba, Sr and Ca, B1 is at least one member selected from the group consisting of In, Y, Zn and Mg, B2 is at least one member selected from the group consisting of Ta and Nb, and M is at least one member selected from the group consisting of Ti, Zr, Hf and Sn, and at least Fe and Cu as sub-components; and a film of a ultraviolet curable resin on the surface of the lens base; wherein when the Fe content and Cu content in the translucent ceramic are x and y, respectively, 3x+y is 40 ppm by weight or less, and the translucent ceramic has an internal transmittance of 90% or more at a sample thickness of 0.6 mm for visible light at a wavelength of 633 nm, and an internal transmittance of 60% or more at a sample thickness of 0.6 mm for ultraviolet light at a wavelength of 365 nm.
