摘要:
Disclosed is a polarization beam splitter and a method of producing the same, in which the polarization beam splitter has superior polarization separation efficiency and has small angle dependence. A transparent base material having a polarization separation film, comprising a dielectric multilayered film, is cemented at the cemented surface of the beam splitter, to provide an array-like plane type polarization beam splitter, wherein an incidence angle θg of light upon the polarization separation film is selected to satisfy a relation θg>45 deg.
摘要:
A display apparatus includes a planar optical modulation device having a transparent substrate and a plurality of pixels disposed thereon so as to be each capable of optical modulation thereat, and a masking member disposed on the transparent substrate and including spacings. The making member includes a layer of a metal compound containing C, O and a metal element. The masking member is effective in reducing a degree of reflection of external light (from a viewer side) while maintaining a sufficient light-interrupting property, thus resulting in a display apparatus exhibiting good display performances.
摘要:
In formation of thin films on both surfaces of a substrate such as a lens or the like, a pair of cluster beam evaporation sources are provided in mutually separate manner in a film forming chamber. The substrate is disposed between the pair of cluster beam evaporation sources. The cluster beam evaporation source includes a crucible which is arranged to be inclined toward the substrate, or which has a nozzle on a lateral face opposed to the substrate.
摘要:
In a method of manufacturing a thin film, evaporated particles are generated by a vapor source and are clustered. The clustered evaporated particles are deposited onto a substrate in a vacuum atmosphere without ionizing the particles. A partial pressure of water in the vacuum atmoshpere is controlled to not more than 5.times.10.sup.-6 Torr. A temperature of the substrate is maintained to be 150.degree. C. or lower. A film according to this method has a high adhesion characteristics and a high mechanical strength without heating the substrate to a high temperature and without damaging the substrate by ions.

In an optical recording medium having an optical recording layer provided on a substrate, a carbide film of a substance selected from among tungsten, boron, molybdenum, hafnium, niobium, titanium, chromium, vanadium, tantalum and silicon is formed on one or each side of the recording layer.
摘要:
A magnetooptical recording medium is provided which comprises (a) a light-transmissive substrate formed of a material selected from the group consisting of plastic and glass, (b) a multilayer film disposed on said light-transmissive substrate, and multilayer film being formed by alternate lamination in three or more odd number of a high-refractive film composed of a high-refractive material and a low-refractive film containing SiO.sub.2 as the main constituent and the film in contact with said light-transmissive substrate being a high refractive film, and (c) a recording magnetic layer disposed on said multilayer film, recording on said magnetic film being performed by a light beam transmitting said substrate and said multilayer.
摘要:
A far ultraviolet dielectric multilayer film is disclosed which is composed of a first group of films on a substrate and a second group of films overlaid on the first group of films. The first group of films comprises alternate layers of a high refractive index dielectric which absorbs rays in the ultraviolet region and a low refractive index dielectric. The second group of films comprises alternate layers of an intermediate refractive index dielectric which does not absorb rays in ultraviolet region and a low refractive index dielectric.
