摘要： The present invention relates to a separation prism assembly, comprising a plurality of optical lenses and a base. These optical lenses are assembled with a cross shape to form the separation prism and further to split incoming light into red, green and blue, by selectively reflecting and filtering, and these three colors are guided into each propagation direction. The base is formed by several mutually independent positioning components. These positioning components have trapezoid contours and are pasted onto the bottom of the separation prism to define the included angle between the optical lenses for setting up the relative positions thereof. An opening is formed by the surrounding area of the trapezoid's top contour and the optical lenses in order to further improve the separation prism's heat dissipation.

摘要： A beam splitter for a digital camera splits light passed through a photographing lens into beams directed to a CCD and a finder optical system. The beam splitter includes at least one optical element provided with a beam splitting surface that is inclined with respect to an optical axis of the photographing lens, and a multi-layer film including a plurality of layers of dielectric materials is formed on the beam splitting surface. The multi-layer film is configured such that the beam splitting surface exhibits a substantially constant reflectivity at least for visible light that is incident on the beam splitting surface at any incident angle within a predetermined range.

摘要： In an optical pickup device, a first light source and a second light source, light emission points of which are not on an identical optical axis, are provided. A first laser light beam and a second laser light beam, wavelengths of which are different from each other, are respectively emitted from the first and second light sources. The first and second laser light-beams reflected from an optical recording medium are diffracted based on different diffraction order, such that the diffracted first and second laser light beams are received by a common light receiving element.

摘要： In a field sequential display device, a desired chromaticity of the white level can be easily achieved and fluctuations in the white level caused by fluctuation factors such as temperature characteristics can be suppressed. A light source comprises red, green, and blue LEDs and a white LED. The white LED includes a blue LED covered with a yellow fluorescent material. One field is divided into display subfields of red, green, blue and white. Only the red LED turns on in the red display subfield, only the green LED turns on in the green display subfield, only the blue LED turns on in the blue display subfield, and only the white LED turns on in the white display subfield. A shutter is controlled in each subfield based on sub-image data of each color.

摘要： An optical head assembly, method, and procedure which generates and then precisely positions multiple light beams onto a target. The system diffracts an input light source into a multiple light beam pattern, or initially generates a multiple light beam pattern, in which individual beams of the multiple light beam pattern are precisely spaced, corrected, focused and directed through a two axis plane to the target with minimal movement of any components of the optical head assembly. Such individual beams can also be individually modulated.
