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

Check here for news, updates, anouncements, and events from DOTI. WE DO WHAT WE LOVE, AND LOVE WHAT WE DO. CALL US < Back New Products Jun 1, 2006 Increases to LS3 product line. Introducing PERMA - Performance Enhanced Replacement of Mylar Applications. DOTI increases the LS3 product line with the option to laminate with acrylic. The LS3 product line is a great option for customers who are looking for quality optical components with the added benefit of structural strength and safety. DOTI pioneers an ultra lightweight mirror product called PERMA . PERMA stands for Performance Enhanced Replacement of Mylar Applications. PERMA mirrors were developed as an improvement over Mylar mirrors which can stretch, sag, lose reflectivity, and quickly show signs of handling and use. PERMA mirrors employ a thin first surface mirror permanently bonded to a lightweight rigid panel. These lightweight panels include custom mounting points on either the backside or sides of the panel.

DOTI has manufactured many optics which allow aggressive light-weighting while providing good structural rigidity of the finished optic through use of integral support ribs. LIGHTWEIGHT SUBSTRATES CONTACT A SALES ASSOCIATE Lightweight Substrates 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 optic through use of integral support ribs. The largest cast lightweight mirror we have ground to date is a 42" diameter. Product Applications Astronomy Projection Solar Simulation Scientific Entertainment KEY BENEFITS With lightweight mirrors, one may retain the structural rigidity of a solid piece of glass with, in most cases, 50% or greater weight reduction. Fixed mounting points can be molded into the non-imaging surface for precise alignment. How can we serve you? CONTACT US

SPHERICAL MIRRORS CONTACT A SALES ASSOCIATE Spherical Mirrors Advances in projection technology and rising simulator specifications require the most precise collimating display surfaces. Exceed current and future specifications with DOTI's Large Area Spherical Mirrors. DOTI produces the hightest quality optical components available, allowing pilots to train in the most realistic environment and giving them an immersive, "out-the-window" view, with depth and realism. Product Applications Used in a variety of industries from solar energy to aerospace research development, precision spherical mirrors are a great way to get spectacular and accurate results. With minimal deviation from sphere RoC (Radius of Curvature) and available sub-wave surface accuracy, our spherical mirrors continue to exceed customer expectation. An array of materials, sizes, thickness, coatings, etc. are available to meet every need. Simulation Military / Civil Aviation Automotive Maritime Gaming / Entertainment Construction CONCAVE SPHERICAL MIRRORS 1 Simulation / Remote Operation As the demand for more realistic simulation increases, so does the need for collimated displays. Collimation within the visual display is the one key aspect of a system that gives the user the most realistic simulation experience. Training with a true depth of field allows for increased performance in the field when compared to zero depth systems. 2 Solar Power Increase energy collection concentration efficiency, reduce system footprint, and improve overall system performance with DOTI precision spherical mirrors. CONVEX SPHERICAL MIRRORS 1 Convex Spherical Mirrors Widely used to expand light paths, convex mirrors can reduce the total number of mirrors needed within a visual system of display. Utilizing DOTI precision spherical mirrors for light path expansion will ensure the most accurate and uniform expansion of light. How can we serve you? CONTACT US

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!
