    The value of collimated light in simulation and gaming is that it provides the viewer with the most accurate and realistic depiction of the simulation activity, unlike flat panel trainers. COLLIMATORS CONTACT A SALES ASSOCIATE Collimators Collimated light is a bundle of light rays traveling parallel to one another which implies the light will not disperse with distance. Collimating Displays have been in existence for at least 30 years. Some credit Singer-Link with developing the first collimating display for training a pilot with a more realistic visual display system that included a television monitor being reflected off a beam splitter and onto a concave spherical mirror, the positioning of which provided the observer with light rays that were essentially collimated.

  • LS3 | Displays & Optical Technologies, Inc.

    Lone Star Shatter Shield is a DOTI first-surface mirror product laminated for added structural strength and safety. LS3 - LONE STAR SHATTER SHIELD CONTACT A SALES ASSOCIATE Fine optics manufactured with robust durability and safety in mind. Lone Star Shatter Shield is a DOTI first-surface mirror product laminated for added structural strength and safety. DOTI has developed the ability to laminate to glass, acrylic, metals, etc. This laminating process is a custom DOTI-developed application that we have already been successful in applying to various requirements including techniques for laminating collimating mirrors to create mirrors that are nearly impossible to rupture. DOTI's original laminating process was developed to meet a customer's need to laminate together dissimilar materials in a highly customized manner. The laminated optical components needed to meet specific transmission characteristics, internal quality requirements, and certain rigidity standards. DOTI successfully developed the product line not only to meet this customer's requirement; we then applied its many successes to several other application areas. A significant benefit of this process is that the laminated materials become highly break and shatter resistant. Even if a customer were to damage this mirror, it will probably be able to be used without compromising its utility, while ordering a replacement mirror. This process has been tested to ANSI Z97.1 (L) Level B. We have verified this process. Verification of process runs or required changes can be accomplished. Product Applications LS3 was developed for use in systems and displays that may be in direct public contact, displays with extreme vibration and sudden stops, or any application where safety is paramount. Simulation Military POS LS3 OPTIONS 1 Hand Selected Glass DOTI provides permanent lamination of the highest quality glass available (without grinding and polishing) as our "standard" LS product. 2 Highest Optical Quality DOTI is able to control it's grinding and polishing processes to an incredible degree and is able to provide customers with extremely flat laminated mirror substrates that are immensely rupture resistant. 3 Laminated Beam Splitters DOTI has laminated beam splitter coated substrates for use where the beam splitters would be used in a public setting. The customers wanted to mitigate risk. DOTI has laminated beam splitting coatings inside a "sandwich" which gives the customer the added safety benefit, as well as having the additional advantage of ensuring that the optical coatings would not be rubbed off with the repeated cleanings needed when optics are subject to public exposure.

  • Mirrors and Lasers in Astroparticle Phys | Displays & Optical Technologies, Inc.

    Mirrors and Lasers in Astroparticle Physics Infrastructures 2nd ASPERA Technology Forum 20-21 October 2011 - EGO/Virgo Site (Cascina), Pisa BACK From Forward : "To some extent, Astroparticle Physics (ApP) can be considered as the science of rare events, arising in some cases from the most violent phenomena in the Universe, happening fortunately far away! Nonetheless, detecting such weak signals and understanding their nature / origin are of paramount importance in our understanding of the fundamental laws governing the Universe. Identifying rare and weak signals requires imagining appropriate experiments and then going from conceptual design to the realisation of sophisticated and large size facilities with technical performances often beyond the exciting technological abilities. Accordingly, to constitute the indispensable large spectrum of expertise, close collaboration / cooperation between academia and industry is a must. ASPERA, a European ERA-Net project started within FP6 (2006 – 2009) and being continued in FP7 (2009 – 2012), has been developing an ambitious approach for i) facilitating the creation of large enough collaborations in ApP in Europe, ii) strengthening / creating bridges between public research institutions and companies, especially via the organisation of Technological Forums. The present event is focused on lasers and mirrors. Actually, new generation of facilities for the detection of Gravitational Waves (GW) and (very) high energy gamma rays (HEGR) are in R&D phases. The first topic deals with one of the most fascinating predictions of the General Relativity, going back to 1916 and still undiscovered! Detectable signals are expected resulting from merging / collision between black holes, binary neutron stars… The third generation interferometic detectors is planned to be constructed underground and use cryogenics technology, with unprecedented requirements on the characteristics and performances of lasers and mirrors. The realm covered by the second topic spans phenomena due to supernovae, pulsars, merging galaxies… Hunting rare events requires a very high selectivity and hence minimised background. The Cherenkov Telescope Array project anticipates various sized telescopes in order to pin down the sources of the HEGR and uncover the mysteries of underlying mechanisms. Here also, the required characteristics and performances go far beyond the state-of-the-art in the ground-based telescopes. In summary, the ApP community needs to impulse highly challenging R&D in optics, lasers and mirrors. Innovations in all those areas will certainly also allow companies to apply the gained expertise in other fields at the heart of social needs and concerns: energy, environment, health…" Connect with us!

    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

    Mirror Facets for the VERITAS Telescopes by E. ROACHE, R. IRVIN, J. S. PERKINS, K. HARRIS, A. FALCONE, J. FINLEY AND T. WEEKES Smithsonian Astrophysical Observatory, 670 Mount Hopkins Road, Amado, AZ BACK From Harvard Abstract : Each of the VERITAS telescopes has 345 adjustable glass facets which were manufactured by D.O.T.I., Roundrock, Texas with slumping and grinding to get the optical figure. The facets were aluminized and anodized at the Whipple Observatory. The parameters (reflectivity, focal length and blur circle) were measured. The design specifications for focal length (12.00 m +/- 1%) and spot size (< 10 mm) were surpassed by a factor of two. The anodizing process will be described and the effect of exposure at the VERITAS site on the reflectivity described.

    (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
