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. 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.

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.

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. 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. Product Applications Collimating systems are an invaluable part of any industry that needs realistic, immersive simulation. We offer customization of size, materials, projectors, etc. Simulation Military Gaming S.T.A.A.G. - Simulation Training and Advanced Gaming A perfect balance of size, realism, and affordability.

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

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
