    Abstract: A system for generating and transmitting energy including prisms, lenses, mirrors, optical conduits, heat filters, light filters, and electricity filters. The lenses comprise lens systems to capture electromagnetic signals coming from any source of radiant energy. Upon receiving the electromagnetic signals, the lens system multiplies n times the intensity of the signals by a method of infinitesimal folding of signals, a method basically consisting of an overconcentration of signals folding onto themselves multiple times in order to produce substantially concentrated signals and to project the substantially concentrated signals into one single optical cable. These substantially concentrated signals are transmitted long distances as they are reflected through the interior of these optical conduits (in a conceptual manner similar to signal reflection in Tiber optics cables). At the distal ends of the optical cable three filters will extract heat, white light and electricity.

  • Publication number: 20130148195
    Abstract: The invention provides a light-transfer imager that can be incorporated into a hyperspectral line-scanner, a spectrograph or a non-diffractive image relay device, and more particularly, to a design having a simpler optical design that is easier to fabricate, and has superior imaging quality than most previous designs. The invention includes a generic first optical assembly to deliver incoming light onto a slit or pinhole, a second optical assembly operating as a refractive corrector that directs incoming light onto a curved reflective diffraction grating or curved mirror such that the spectrally dispersed or reflected light (dependent upon the particular embodiment) passes back through the same second optical assembly which focuses that light onto a focal plane array (FPA) in approximately the same plane as the slit. The slit and the FPA are preferably displaced symmetrically on opposite sides of the optical axis of the refractive corrector.

  • Patent number: 8456745
    Abstract: A first embodiment is a lens system having a plurality of refractive and reflective spherical elements that work as a magnifier to produce a distortion free, less than 1%, image with optical correction over a wide field of view. The system has at least one concave reflecting surface, and at least three convex refracting surfaces with the sign of the radius of one of the convex refracting surfaces being opposite of the sign of the radius of remaining two convex refracting surfaces. A second embodiment is a lens having a concave reflecting element which is on a substrate that is a negative lens by transmission with an index of refraction between 1.6<nd >2.0 and a dispersion 49<?d>15. This is used in combination with at least 3 positive refracting surfaces with less dispersive power than the negative element and with the sign of the radius of one of the positive elements being opposite from the sign of the radius of the remaining positive elements.

  • Patent number: 8419191
    Abstract: An optical system with short total length to project a high quality large image. The system projects an image onto a projection surface, and includes a lens system having a plurality of lenses, and one or more curved mirrors. Light flux of an enlarged image shooting out from the lens system to the projection surface is incident onto a mirror surface of the one of the curved mirrors first of all. Distances OAL and Y satisfy a requirement 20 <OAL/Y <30. OAL is between the image surface and the surface of the curved mirror nearest the projection surface and along an optical path shared by the most lenses of the lens system, and on the image surface. Y is between the optical axis shared by the most lenses and an edge of the image surface which is farthest from the optical axis shared by the most lenses.

    Abstract: A mirror (1) for a microlithography projection exposure apparatus including a substrate (3) and a reflective coating (5). A functional coating (11) between the substrate (3) and the reflective coating (5) has a local form variation (19) for correcting the surface form of the mirror (1), wherein the local form variation (19) is brought about by a local variation in the chemical composition of the functional coating (11) and wherein a thickness of the reflective coating (5) is not changed by the local variation in the chemical composition of the functional coating (11). The local variation in the chemical composition of the functional coating (11) can be brought about by bombardment with particles (15), for example with hydrogen ions.

    Abstract: An LED module includes an LED having a central axis I, and a lens. The lens has an incident face for incidence of the light of the LED and an opposite emitting face for refracting the light of the LED out of the lens. The emitting face of the lens has a central axis II. The central axis II is offset from the central axis I and located at one side of a plane ZOX of an XYZ coordinate with an original O which is located at a center of the LED, in which the central axis I is coincident with the Z axis. The light beams emitted from the one side of the plane ZOX are stronger than the light beams emitted from the another side of the plane ZOX after the light beams emitted from the LED pass through the lens.

  • Patent number: 8259398
    Abstract: Disclosed are high numerical (NA) catadioptric objectives without a central obscuration, and applications thereof. Such objectives can operate through a wide spectral bandwidth of radiation, including deep ultraviolet (DUV) radiation. Importantly, refractive elements in the catadioptric objectives can be manufactured from a single type of material (such as, for example, CaF2 and/or fused silica). In addition, the elements of such catadioptric objectives are rotationally symmetric about an optical axis. The catadioptric objectives eliminate the central obscuration by (1) using a polarized beamsplitter (which passes radiation of a first polarization and reflects radiation of a second polarization), and/or (2) using one or more folding mirrors to direct off-axis radiation into the pupil of the catadioptric objective. An example catadioptric objective is shown in FIG. 2.

  • Patent number: 8254039
    Abstract: A variable magnification optical system projects an image onto a screen with a sufficient magnification without requiring a large-sized mirror. The variable magnification optical system includes a first optical system through which a light beam modulated with an image signal corresponding to the image is passed; a second optical system disposed downstream of the first optical system in a direction of travel of the light beam along an optical axis; and a reflective optical element having a magnification power that is configured to reflect the light beam from the second optical system toward the screen. A magnification of the image projected on the screen is changed by moving the reflective optical element relative to the object plane, thus changing a distance between the screen and the reflective optical element, while an incident angle of the light beam on the screen is maintained substantially constant.
