摘要： A phase difference element capable of reducing reflection of incident light and a manufacturing method for the phase difference element are disclosed. The phase difference element includes a transparent substrate 11, an interface anti-reflection film group 12 and an obliquely vapor deposited film 13. The interface anti-reflection film group is composed by one or more of alternately high and low refractive index films, with the film thicknesses of the respectively films being equal to or less than the wavelength of light in use. The obliquely vapor deposited film is formed by a plurality of layers of a dielectric material. These layers are alternately obliquely vapor deposited from two directions differing by 180° from each other. The refractive index of the interface anti-reflection film group 12 is higher than the refractive index of the transparent substrate 11 and lesser than that of the obliquely vapor deposited film 13 (FIG. 1).

摘要： A highly pure hexagonal boron nitride single crystal not influenced by impurities and capable of high-luminance short wave ultraviolet light emission reflecting inherent characteristics is provided; a high-luminance ultraviolet light emitting element is provided by using the above single crystal; and utilizing the above element, a simple compact low-cost long-lived far ultraviolet solid-state laser and far ultraviolet solid-state light emitting apparatus are provided. A highly pure hexagonal boron nitride single crystal having a single light emission peak in the far ultraviolet region of up to a wavelength of 235 nm is produced by melting said boron nitride crystal as raw material in the presence of a highly pure solvent under high-temperature and high-pressure, followed by crystallization. A light emitting element or a light emitting layer comprised of the obtained crystal is excited with electron beams, and the thus generated far ultraviolet light resonated or without resonation is taken out.

摘要： An objective lens is configured of a first crown-glass lens and a second flint-glass lens, whereby it can exhibit substantially identical optical properties at a plurality of recording/reproducing light source wavelengths, particularly, in both 650 nm and 405 nm wavelength bands. Also, by maximizing the difference in glass transition point between the first and second lenses, one of the first and second lenses having a higher glass transition point is molded first, to allow that first molded lens to serve as a mold tool for molding the other lens. This dispenses with the steps of aligning and adhesive bonding the two lenses, whereby this objective lens can be used at a plurality of wavelengths as a single objective lens, and thus an information recording/reproducing apparatus can be of a simple configuration.

摘要： The improved silver halide photographic material comprises a support having an antistatic coating thereon that contains a water-soluble conductive polymer, hydrophobic polymer particles and a curing agent which is a bifunctional ethylene oxide type curing agent that is to be cured by exposure to electron beams or X-rays. This silver halide photographic material may contain a tetrazolium compound or a hydrazine compound in order to prevent desensitization due to aging. At least one hydrophilic colloidal layer may be provided on the antistatic coating, which colloidal layer contains an epoxy curing agent having a hydroxy group.
