  • Patent number: 8477413
    Abstract: An optical element for reflecting solar light has excellent weather resistance, and furthermore, a high reflectance in a wide band. When solar light enters an optical element (OE), light (L1) in a short wavelength band among the solar light is reflected by a dielectric multilayer film (DF). Other light (L2) in longer wavelength bands are passed through the dielectric multilayer film (DF), then a base material (SS), and reflected by a metal deposition film (MV) to pass through the base material (SS) and the dielectric multilayer film (DF). Thus, high reflectance in a wide band is ensured.

  • Patent number: 8437084
    Abstract: On the light-entering surface side of a base material 10, a coating layer 11 in which a high-refractive layer and a low-refractive layer are sequentially disposed alternately on one on the other is provided for blocking infrared radiation. One of the high-refractive layers is configured by an ITO film 11a so that the conductivity is increased on the surface of the coating layer. Herein, in view of preventing, to a further extent, the attachment of dirt and dust by providing the conductivity to the surface of the coating layer, it is desirable if the outermost high-refractive layer is made of a transparent conductive material. Moreover, it is desirable if the total layer thickness is 140 nm or smaller for the refractive layers formed outside of the high-refractive layer made of the transparent conductive material.

    Abstract: The present invention discloses a progressive-refractivity antireflection layer and a method for fabricating the same to eliminate light reflection occurring in an interface. The present invention is characterized in being fabricated via depositing a first material and a second material, and having a refractivity (neff) gradually varying with a thickness thereof and ranging between a refractivity (n1) of the first material and a refractivity (n2) of the second material. No matter at what thickness the refractivity (neff) of the antireflection layer is measured, the refractivity (neff) meets an effective medium theory expressed by an equation: neff={n12f+n22(1?f)}1/2, wherein f is a filling ratio of the first material of the antireflection layer.
