  • Patent number: 9140901
    Abstract: A system and method for scanning a wide band beam is presented. An apparatus includes a pair of prism triplets. Each prism triplet includes a first wedge prism, a second wedge prism and a third wedge prism all formed with different optical materials. In operation, a beam passing through the wide band team scanning apparatus first passes through the first, second and third wedge prisms of the first prism triplet. The beam then passes through the wedge prisms of the second prism triplet in a mirrored order (the third, then second, then first wedge prisms) than that of the first prism triplet. This apparatus with two prism triplets allows wide band light transmitted through it to emerge with its plurality of different wavelengths of light travelling in the same direction to equalize net dispersive effects each of different wavelengths.

  • Publication number: 20120327507
    Abstract: Light management film constructions contain a first optical film having a first major surface and a second major surface opposite the first major surface. The first major surface is a micro structured surface with asymmetrical structures. The asymmetrical structures form an ordered arrangement of a plurality of multi-sided refractive prisms, with the multi-sided refractive prisms having a cross section of 3 or greater sides. A second optical film contacts and is bonded to substantially all of the structures of the first major structured surface of the first optical film. The light management constructions can be incorporated into optical articles such as windows.

  • Patent number: 8264680
    Abstract: A biochip reader wherein spectroscopic information of a sample under analysis is arranged in spaces between images of the sample arranged on a biochip. The reader comprises a confocal microscope and the biochip comprises a transparent substrate to allow passage of the excitation light and fluorescent light from the sample with the excitation light being applied from the side opposite that on which the samples are arranged so that noise from dust and the like is avoided by the transmitted light avoiding contact with the dust. Another aspect is an electrophoresis system wherein different coloring material are used for each of a variety of target substances, so that the same lane and area are utilizable to concurrently detect a polychrome fluorescent pattern of the different targets. A confocal scanner or fluorescence imaging system is used with a plurality of filters to detect the multi-colored fluorescences of the target substance.

  • Patent number: 8157390
    Abstract: The invention discloses a projecting system. The projecting system includes two sets of lens. The first set of lens has a first focal length for focusing an incident ray of light to form a first image. The second set of lens has a second focal length for projecting the first image to form a second image. The two sets of lens are separated by a lens-apex distance relative to the light path between the two sets of lens. The second focal length is smaller than or equal to the lens-apex distance. A difference between the second focal length and the lens-apex distance is smaller than or equal to a half of the first focal length.

    Abstract: A spectrometer comprises a detector array and a prism. The prism comprises a first prism element comprising a substantially crystalline crown material, and a second prism element contacting the first prism element, the second prism element comprising a substantially crystalline flint material. The spectrometer further includes optics configured to direct light at least twice through the prism. The prism is configured to disperse light received from the optics at an incident angle therethrough into constituent spectra in visible and infrared wavelength bands that are dispersed from the prism at angles offset from the incident angle. The constituent spectra are directed onto the detector array with approximately equal dispersion across the visible and infrared wavelength bands. Among other things, desirable material selections for the first and second prism elements are also disclosed.
