    摘要： The present invention is directed to a proteorhodopsin mutant having improved optical characteristics. One improved optical characteristic is having a lower pH (pKrh) at which equal concentrations of the acidic and basic spectral form of the proteorhodopsin molecules are present. Another improved optical characteristic is having a smaller difference in maximum absorption wavelength between the basic and the acidic form. The mutant comprises a mutation in a conserved amino acid residue of a proteorhodopsin variant, which causes spectral shifts. A preferred mutation site is a conserved histidine residue at amino acid position 75 of Bac31A8, or position 77 of Hot75m1, or its equivalent position of a proteorhodopsin variant. Another preferred mutation site is a conserved arginine residue at amino acid position 94 of Bac31A8, or position 96 of Hot75m1, or its equivalent position of a proteorhodopsin variant.

    摘要： The invention discloses a flat-plate lens to be built in an optical recording medium for improving the image-forming characteristics of the recording medium. The flat-plate lens of the invention comprises a layered thin film having a periodical structure in the direction of thickness thereof corresponding to a wavelength slightly longer than the wavelength of the light used for recording and retrieving information into and from the recording medium. The thin film of a periodical structure is formed by alternate lamination of pluralities of layers two materials having different refractive indices such as a combination of MgF2 and ZnS. When the thin film having such a periodical structure is formed with good uniformity allover the surface, the image-forming performance on the recording layer can be uniform irrespective of the position on the flat-plate lens.
