摘要:
While one side of a lens L is held by a suction-holding member 17 and the suction-holding member 17 is moved by the moving mechanism, a coating process, a drying process, and a curing process are sequentially performed in respective receptacles disposed independently of each other. A suction force applied to the lens L by the suction-holding member 17 is controlled by a control section 22 in accordance with each of the receptacles in which the suction-holding member 17 is positioned.
摘要:
An optical component for an optical pick-up for converging a laser beam having a particular wavelength onto a recording layer of an optical disc. The optical component comprises a base material formed of a resin composition, an undercoating which is formed of three layers of thin films having a same main constituent and is formed on a top surface of the base material, and a functional thin film formed on a top surface of the undercoating. In this configuration, each of a first layer and a third layer of the undercoating is a thin film formed without introducing oxygen, and a second layer is a thin film formed while introducing oxygen. A film thickness of the undercoating falls within a range of 160 nm to 270 nm, and film thicknesses of the thin films constituting the undercoating are substantially equal to each other.
摘要:
Hybrid films, such as those having good abrasion-resistance and defogging properties, antireflection films including it, optical products, and methods for restoring the defogging property of the hybrid films are disclosed. The hybrid films having a defogging property may be obtained through vapor deposition of an organic compound having a hydrophilic group and a reactive group along with silicon dioxide or with silicon dioxide and aluminum oxide. The antireflection film may be formed on a substrate having the hybrid film as the outermost layer opposite to the substrate. The optical product may comprise a plastic substrate and the antireflection film having the hybrid film. A method for restoring the defogging property of the hybrid film of the optical product may include washing the hybrid film.
摘要:
The present invention is directed to an optical element having an antireflection film formed on a plastic substrate, wherein the reflectance of the antireflection film is low while the transmittance thereof is high. The impact resistance, the adhesiveness, the heat resistance, the abrasion resistance and the alkali resistance of the antireflection film on the plastic substrate are superior.The optical element having an antireflection film has at least one layer of the antireflection film that is a hybrid layer made of an inorganic substance and an organic substance.
