Abstract

See full text

An optical power prism that may be used in folded lens systems that consists of a glass prism and a glass lens attached to a surface of the prism using a thin layer of optical glue or by optical contact. The glass lens does not have a flange and thus the prism can be smaller than prisms used in conventional power prisms with the same lens effective area, thus reducing the Z-height of the power prism when compared to conventional power prisms. An optical glass may be used for the lens that has a higher refractive index than can be provided by optical plastic which allows the lens to be thinner than plastic lenses. The lenses may be formed by molding a glass wafer to form lens shapes on a first surface of the wafer; the molded wafer is then ground from a second surface to singulate the lenses.
