DOTI manufactures custom mirrors and optics from a wide variety of glass and composite materials in sizes up to 134+". YOU DESIGN. WE BUILD. CONTACT US PRODUCTS DOTI manufactures custom mirrors and optics from a wide variety of glass and composite materials in sizes up to 134+". We are currently in the process of expanding to part sizes of up to 144", with in-house coatings available for parts of up to 108", and can work with customers on coatings for larger parts. DOTI's innovative techniques utilize specialized materials such as Optical Composites, Soda Lime Float Glass, Quartz, Fused Silica, ULE®, Starphire®, Borofloat®, and BK-7®. DOTI supplies optical coatings customized for specific tasks and wavelengths, using superior Enhanced Aluminum, Protected Aluminum, Gold, Silver, UV Coatings utilizing Hafnium, and others. Coatings can be engineered to perform over a broad spectral range. Products Collimators Our STAAG and WAC collimated display systems feature industry leading Fields of View, offering a wide range of capabilities for the simulation and gaming industries. More Info Tessellated Arrays DOTI has supplied mirrors for tessellated arrays to multiple, significant programs. Our quality, rate of production, accuracy and willingness to address customers' design needs had established DOTI as the supplier of choice for such projects. More Info Spherical Mirrors DOTI has the capabilities to manufacture a wide range of the highest quality mirrors required by today's demanding simulation industry. These mirrors include large spherical, flat, and beam splitters. More Info PERMA Mirrors DOTI has pioneered an ultra lightweight mirror product that we have named PERMA. PERMA stands for Performance Enhanced Replacement of Mylar Applications. Our mirrors employ very thin first surface mirrors, permanently bonded in a proprietary manner to very thin lightweight rigid panels. More Info Lightweight DOTI has manufactured many optics utilizing our ability to bend ("slump") glass, as well as from cast substrates, which allow aggressive light-weighting while providing good structural rigidity of the finished optics through use of integral support ribs. The largest cast lightweight mirror we have ground to date is a 42" diameter. More Info LS3 Lone Star Shatter Shield (aka LS3) is a proprietary lamination process which allows us to laminate glass, acrylic, etc. This laminating process is a custom application that we have been successful in applying to various requirements, including laminating collimating mirrors to create mirrors that are nearly impossible to rupture.

VERITAS, 1ES 1218 + 30.4 and the Extragalactic Background Light by Luis Valcarcel - Centre for High-Energy Physics, Department of Physics - McGill University VERITAS, 1ES 1218 + 30.4 and the Extragalactic Background Light VERITAS, 1ES 1218 + 30.4 and the Extragalactic Background Light by Luis Valcarcel - Centre for High-Energy Physics, Department of Physics - McGill University Montreal, Quebec, Canada November 11, 2008 BACK From Abstract : Blazars are extremely powerful astrophysical objects that emit radiation up to the TeV regime. 1ES 1218 + 30.4 is one such object. It was observed from December 20, 2006, to March 20, 2007, by the γ-ray experiment VERITAS (Very Energetic Radiation Imaging Telescope Array System), an array of four 12-m atmospheric Cerenkov telescopes located in southern Arizona. These observations are analyzed and 1ES 1218 + 30.4 is detected with high significance. The observed spectrum is also found to be in agreement with previous results and is here measured to be (2.2 ± 0.3stat. ± 0.4sys.)×10−12cm−2s−1 TeV−1(E0.8 TeV )−2.8±0.2stat.±0.2sys.in the 350 GeVto 1.9 TeV energy range. The spectrum is used to constrain the extragalactic background light by unfolding the intrinsic spectrum for many possibilities and keeping only the ones that lead to physically permissible intrinsic spectra. The direct measurements of the extragalactic background light at near infrared wavelengths are challenged by the limits derived in this work. Connect with us! How can we serve you? CONTACT US

DESIGN AND PERFORMANCE OF A TRIPLE SOURCE AIR MASS ZERO SOLAR SIMULATOR by Phillip Jenkins and David Scheiman (Ohio Aerospace Institue), and David Snyder (NASA Glenn Research Center). (NASA) Design and Performance of a Triple Source Air Mass Zero Solar Simulator DESIGN AND PERFORMANCE OF A TRIPLE SOURCE AIR MASS ZERO SOLAR SIMULATOR by Phillip Jenkins and David Scheiman (Ohio Aerospace Institue), and David Snyder (NASA Glenn Research Center). BACK From Abstract: "Simulating the sun in a laboratory for the purpose of measuring solar cells has long been a challenge for engineers and scientists. Multi-junction cells demand higher fidelity of a solar simulator than do single junction cells, due to a need for close spectral matching as well as AM0 intensity. A GaInP/GaAs/Ge solar cell for example, requires spectral matching in three distinct spectral bands (figure 1). A commercial single source high-pressure xenon arc solar simulator such as the Spectrolab X-25 at NASA Glenn Research Center, can match the top two junctions of a GaInP/GaAs/Ge cell to within 1.3% mismatch, with the GaAs cell receiving slightly more current than required. The Ge bottom cell however, is mismatched +8.8%. Multi source simulators are designed to match the current for all junctions but typically have small illuminated areas, less uniformity and less beam collimation compared to an X-25 simulator. It was our intent when designing a multi source simulator to preserve as many aspects of the X-25 while adding multi-source capability." Connect with us! How can we serve you? CONTACT US
