    • PROBLEM TO BE SOLVED: To provide a lens for astigmatism correction which is more advantageous in terms of astigmatism as compared to conventional lenses and its manufacturing method.
      SOLUTION: A synthetic face synthesized with a non-toric face, the same astigmatism correction face and progressive refractive face as an astigmatism correction face is formed on the face on the object side of positive in an equivalent spherical surface degree at a fitting point in a distal region. The face on an eyeball side of the lens is formed to a spherical surface shape. As a result, the lens for astigmatism correction suppressed in the aberrations more than heretofore can be provided.

    • PROBLEM TO BE SOLVED: To provide an optical body having a photocatalytic multilayer thin film formed thereon which has sufficient anti-fogging effect and hardly induces water stain and which has easy wiping property against dirt depositing on the film. SOLUTION: The optical body has an antireflection film directly formed on the surface of an optical base or via other coating layers. The antireflection film is constituted by alternately depositing low refractive index layers and high refractive index layers and has the layer configuration that the uppermost layer consists of magnesium fluoride as a low refractive index layer having no hydrophilicity, and that a high refractive index layer just below the uppermost layer consists of titanium dioxide as a metal oxide layer having photocatalytic activity. Thereby, the obtained optical body hardly induces the water stain and has easy wiping property against dirt depositing thereon. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:为了提供一种具有形成在其上的光催化多层薄膜的光学体,其具有足够的防雾效果,并且几乎不引起水渍,并且对于在膜上的污垢沉积具有容易的擦拭性能。 解决方案:光学体具有直接形成在光学基底的表面上或经由其它涂层的抗反射膜。 抗反射膜由交替沉积低折射率层和高折射率层构成,并且具有最上层由氟化镁作为不具有亲水性的低折射率层构成的层构造,以及刚好在 最上层由二氧化钛作为具有光催化活性的金属氧化物层组成。 由此,所获得的光学体几乎不引起水渍,并且对其上的污垢沉积具有容易的擦拭性能。 版权所有(C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide an interference type near IR cut filter with little variance of fabrication in the manufacturing process in which gradually decreased transmission property in the region from the visible ray region to near IR rays can be stably obtained.
      SOLUTION: Two or more kinds of thin films having different refractive indices are alternately deposited to form multilayered films on the surface of a transparent substrate (A). A multilayered film (1) showing high transmission property in the visible ray region and showing gradually decreased transmission property in a long wavelength region of visible rays is formed on the top face of the substrate, while a multilayered film (2) showing high transmission property in the visible ray region and showing low transmission property in the near IR region is formed on the back face of the substrate.
