    摘要: PROBLEM TO BE SOLVED: To provide a wide band anti-reflection film which reduces variation of transmissivity characteristic of the anti-reflection film when optical elements are mass-produced while attaining broadband adaptation of the anti-reflection film. SOLUTION: The wide band anti-reflection film 6 is constituted by laminating seven layers of thin films on a substrate 7. In regard to thin film constituting materials, a first thin film 8 is film-formed of MgF 2 which is known to have strong adhesiveness to the substrate 7. Further in the wide band anti-reflection film 6, a second thin film 9 is film-formed of H 4 (a mixture composed of La and TiO 2 ), a third thin film 10 is film-formed of MgF 2 , a fourth thin film 11 is film-formed of H 4 , a fifth thin film 12 is film-formed of MgF 2 , a sixth thin film 13 is film-formed of H 4 and a seventh thin film 14 is film-formed of MgF 2 in order from a surface of the first thin film 8.

    摘要: PROBLEM TO BE SOLVED: To provide an optical antireflection film with a silicon oxide film which ensures adhesion to a synthetic resin substrate, environmental resistance, wear and chemical resistances and has suitable optical characteristics, and to provide a process for forming the same. SOLUTION: A first SiO film having a refractive index substantially equal to the refractive index of an acrylic resin substrate is formed to a thickness of about 200 nm on the substrate, and a second SiO film having a refractive index assuming a value falling within the range from 1.48 to 1.62 is formed to a thickness of about 200 nm on the first SiO film. Further, in the case of an HLHL type antireflection film for example, a TiO 2 film having a refractive index assuming a value falling within the range from 2.2 to 2.4 is formed as the layer next to the outermost layer with a special ion plating apparatus.

    摘要: PROBLEM TO BE SOLVED: To solve a problem wherein the function of an optical device is degraded because of lower transmittance since an antireflection film having a designed center wavelength between 180 and 220 nm needs to have a thickness greater than a specified level to maintain an antireflection function. SOLUTION: An antireflection film includes alternately deposited high refractive index layers and low refractive index layers. The antireflection film exhibiting sufficient antireflection characteristics is obtained even if the geometrical thickness thereof is small by taking the refractive indexes and extinction coefficients of the layers into account and considering the extinction coefficient of the antireflection film. An optical device having the antireflection film on a substrate exhibits high transmittance and has excellent optical characteristics. COPYRIGHT: (C)2004,JPO

    摘要: PURPOSE:To extend the operating life of optical parts and to reduce an overall cost by operating the optical parts coated with the optical film of arsenic triselenide in an inert gas under the irradiation of a laser. CONSTITUTION:An antireflecting film 2 coated to both end of a fiber 1 is constituted of the arsenic triselenide films 3, 5 and a lead fluoride layer 4 and seals the fiber 1 in an armored cable 6 which is shielded from the outdoor air by a window 7 and a condenser lens 8. The laser beam 12 is introduced through the window 7 and the film 2 into the fiber 1 and is emitted from the lens 8 side. The insert gas such as dry gaseous nitrogen is thus sealed into the cable 6 and the antireflecting film of the arsenic triselenide is formed and therefore the operating life of the optical film is considerably extended.
