20100007964 | LIGHT INTEGRATING DEVICE FOR AN ILLUMINATION SYSTEM AND ILLUMINATION SYSTEM USING THE SAME - A light integrating device for an illumination system and an illumination system. The illumination system includes a first light source module and a second light source module providing a first light and a second light, respectively. The device includes first and second light collecting elements and a beam splitting element. The first light travels into the first light collecting element and is split into a plurality of light groups by the beam splitting element. At least one light group travels into the second light collecting element from the beam splitting element. The second light travels into the second light collecting element, is reflected by the beam splitting element and emits out from the second light collecting element along the principle axis of the light integrating device together with the at least one light group which is split from the first light and travels into the second light collecting element. | 01-14-2010 |
20110026129 | PRISM BEAMSPLITTERS - Embodiments of the present invention are directed to single prism beamsplitters and compound beamsplitters formed from combining one or more of the single prism beamsplitters. In one embodiment, the beamsplitters can be configured to produce one or more split beams of light that can emerge at angles other than 90° to one another. The prisms of the beamsplitter embodiments are configured so that light propagating through prisms encounter one or more intermediate planar surfaces at various angles with respect to the path of the light. A certain number of the intermediate planar surfaces can be angled so that the light transmitted along a particular path undergoes total internal reflection within the prism. A number of other intermediate planar surfaces are angled so that the light transmitted along a particular path does not undergo total internal reflection. | 02-03-2011 |
20140111866 | OPTICAL ASSEMBLY AND LASER ALIGNMENT APPARATUS - An optical assembly is provided for use with a laser alignment system that has a laser emitter and at least one photosensitive target. The optical assembly includes first and second 90° pentaprisms disposed for receiving an input beam produced by the laser emitter. The first and second 90° pentaprisms are oriented to produce first and second reflected beams that are parallel to one another. The optical assembly further includes first and second beam diverters disposed and oriented to receive the reflected beams from the first and second 90° pentaprisms and to produce first and second output beams that are mutually perpendicular. The first and second 90° pentaprisms may be see-through pentaprisms to produce a third output beam that is colinear with the input beam and perpendicular to the first and second output beams. | 04-24-2014 |
20140168786 | VIDEO WALL AND MULLION ELIMINATION STRUCTURE THEREOF - An exemplary video wall includes two display panels and a mullion elimination structure. The display panels each include a main body and a bezel. The mullion elimination structure includes a triangular prism and two transparent quadrangular prisms. The triangular prism includes a first bottom and two opposite first sides. The first bottom is attached to and covers two adjacent bezels of the display panels. The transparent quadrangular prisms each include a second bottom attached to the main body of one display panel, a second side, and an opposite third side . The third side is attached to the corresponding first side of the triangular prism. The second side is coated with a transflective film for partially transmitting and partially reflecting light incident thereon. A reflective surface is formed between the first sides of the triangular prism and the second sides of the quadrangular prisms for reflecting light incident thereon. | 06-19-2014 |
20140218805 | PATTERN CONTROLLED BONDING - Disclosed is fixation by means of any type of adhesive of two- or more parts in an assembly consisting of one or more inhomogeneous part internally joined rigid together, e.g. lenses buildup as doublets or higher—or as the detailed example; Polarizing beam splitters. | 08-07-2014 |
20150370077 | BEAM SPLITTING SYSTEM FOR LASER RANGING - A beam splitting system for laser ranging includes a roof half-pentaprism, an isosceles prism and a compensating prism. Due to different compensating prisms, there are four light splitting combinations in total. Light of a certain wavelength is incident from one side of the roof half-pentaprism, and is reflected therein for several times and finally emergent into the isosceles prism where it is reflected for several times and finally emergent in a direction consistent with an incident light axis. Light of another wavelength is incident from one side of the compensating prism, and finally emergent from one side of the roof half-pentaprism or one side of the isosceles prism. Different light splitting ways may be caused due to different positions of both prisms and data LCDs. A number of different optical ranging systems will be provided if a laser rangefinder employs different light splitting combinations. | 12-24-2015 |
