  • Assessment and potential use of concentrating solar power plants in Serbia and Republic of Srpska
    Flat mirrors with plastic reflectors are formed by stretching plastic foils over the firm frame [14]. Aluminum foil mirrors . For the manufacture of parabolic solar concentrators alumi- num foil is mostly used due to its lightness, high reflection coefficient and adhesive easily fixed to the supporting structure [12].
  • On creating multilayer X-ray focusing mirrors
    Depending on the cylindrical surface shape (ellip tic or parabolic ), the mirrors are used for light re col limation with a particular scale factor, or for making a parallel beam out of a divergent beam (collimation) and vice versa (focusing a parallel... We developed a method for manufacturing cylin drical mirrors [1–5] based on three methods: elastic bending, plastic bending, and replication.
  • Advanced PV concentrators
    This means that they can be manufactured with the same techniques (typically plastic injection molding or glass molding) and that their production cost is the same i.e., with a high potential for low cost and high optical efficiency. We have developed two different Kohler-based designs (1) Fresnel lens + secondary element (Fresnel-R); (2) Parabolic mirror + secondary reflective element + tertiary element (XXR).
  • Renewable energies
    By latter becomes the whole concentrator surface brought into a shaping process into a parabolically curved shape. The mirror segments can directly consist by it of verspiegeltem glass. But they can be manufactured also from facets that are covered with a verspiegelten film or thin... These facets are mostly carried out with prestressed membranes of metal or plastics (Stretched membrane technology).
  • Multivariate determination of 13 CO2 /12 CO2 ratios in exhaled mouse breath with mid-infrared hollow waveguide gas sensors
    The gas cell was manufactured from a solid aluminum block and optimized for minimum volume (approx. 100... The entire sensor system was encased in a flexible plastic housing and kept under pure nitrogen (MTI... Collimated MIR radiation from the FT-IR spectrometer (a) was deflected by a planar gold-coated mirror (diameter, 2 in.; Janos Technology Inc., Keene, NH, USA) onto an off-axis parabolic mirror (OAPM) (c) (diameter, 2 in.; focal length, 2 in.; Janos...
  • A prototype catalogue: DOE National Laboratory technologies for infrastructure modernization
    With this accessory, a collimated beam is tranferred several meters down a 2 in. diameter pyrex glass tube, and focused by a parabolic mirror mounted within the barrel. As a diagnostic tool, the device adds a new dimension to monitoring of manufactured items and R&D... Applications include monitoring the ageing of adhesives and plastics , determining the moisture and content of plastics and...
  • Industry News: Metals, Polymers, Ceramics (May 2012)
    news briefs A precision-extruded aluminum framing system manufactured by Norsk Hydro ASA, Oslo, Norway, was installed... It uses parabolic mirrors to concentrate sunlight onto crystalline silicon PV cells. BASF, Ludwigshafen, Germany, is partnering with Bekaert (Belgium) and voestalpine Plastics Solutions (Netherlands), to develop thermoplastic components...
  • The development of small concentrating PV systems
    Collector F - Multiple line-focus mirror parabolic troughs. with once per day manual tracking to follow the sun’s changing declination: concentration ratio6x. Mirror surfaces, particularlyof secondaries, should not be made of plastic , which can be damaged by overheating if... The design should lend itself to large-scale manufacture , and should minimise the mass of each material...
  • Rotational molding of thin parabolic products
    Thin-walled (film) products, such as headlamps, mirrors with a parabolic surface are manufactured by stamping in die molds. A liquid plastic film is applied to the mold fluid surface.
  • Atmospheric Cosmic Ray Detectors
    The reflector consists of 380 round facets with 60 cm diameter, manufactured from ground glass, aluminised and quartz... Each mirror facet is positioned with two motors to optimise the alignment for a narrow point spread... In the CANGAROO project, the 4 telescopes have parabolic reflectors of 10 m diameter with a 8 m focal... The reflector is formed by 114 spherical mirror facets of carbon fibre reinforced plastic .
