“Sunrise” over the Arctic Ice
Balloon flight for solar telescope equipped with
lightweight “Zerodur” mirror begins
Esrange Space Center, near Kiruna (Sweden) / Mainz
(Germany), June 10, 2009 — On Monday, “Sunrise” began
its roughly five-day passage over the Arctic Circle. The
solar telescope with a 1.1 meter aperture contains a mirror
substrate made of the zero expansion glass ceramic
“Zerodur” from SCHOTT. Lightweight structures made it
possible to reduce the weight of the mirror substrate by
around 85 percent. More

Magic Moments in the Himalayas
SCHOTT supplies “Zerodur” mirror substrate for
India’s largest astronomical telescope
Mainz (Germany), April 7, 2009 –The emerging nation India
is building Asia’s largest imaging telescope at the foot of
the Himalaya Mountains, northeast of New Delhi. It should
be ready for use and set its focus on the universe over the
northern hemisphere by 2012. With a 3.7 meter mirror
made of the glass ceramic “Zerodur” from SCHOTT, the
telescope developed by the Belgian company AMOS will
rank among the world’s top 30. ARIES, an autonomous
research institution under the Department of Science and
Technology of the Government of India, is the nodal
organization for this international project.

Protection when lasers catch the eye
SCHOTT optical glass filters ensure safer vision
Lasers with a superior beam quality can be set at power densities that are sufficient to evaporate metal or ceramics. However, the intense light that turns lasers into powerful tools in more and more applications also poses a major threat to the human eye. When integrated into protective eyewear and window frames, special optical filters protect the laser engineer’s vision. More

SCHOTT sets standards for quality
New testing system for measuring the stress birefringence of optical materials and components
“It takes only 30 seconds to record how stress is distributed across the entire object. This allows us to control the quality of our optical materials extremely quickly and with great precision,” explains Dr. Ralf Jedamzik, Application Manager for Advanced Optics at SCHOTT. SCHOTT plans to use the new testing device to optimize its manufacturing of larger, extremely homogeneous optical materials and components even further. More

Well prepared for major “Zerodur” projects
Process innovations and expansion of mass manufacturing are paying off for SCHOTT
Since 2003, we have invested more than 15 million euros to expanding and optimizing our manufacturing. By increasing our melting capacities, optimizing processes, achieving increases in quality and new technologies, we’ve been successful in improving our international competitiveness, as well, even despite the strength of the euro,” explains Dr. Thomas Westerhoff, Director of the Product Division “Zerodur” at SCHOTT. “At our main site in Mainz, Germany, we are able to rely on resources and know-how in various fields of technology. This not only increases our power of innovation, but also the flexibility that one needs in order to remain successful in the project business. We are now in an excellent position to be able to benefit from the global demand for Zerodur in the required quality and volumes,” he adds. More

DAWN Space Probe Set for First Light
Mainz (Germany) / Los Angeles (USA), October 19, 2007—It will be dark when the protective lid that covers the camera eye of the space probe DAWN opens for the first to set its sight on two almost pixel-sized light dots: the asteroids Vesta and Ceres. During the mission to the two planetoids in the asteroid belt of our solar system, the cameras on board will be used for the navigation of the scientific probe for the five billion-kilometer long journey through space in addition to the scientific exploration of the celestial bodies.

Glass beats plastic
Until now, diffractive optical elements for mass production could only be manufactured out of plastic, with all of its known weaknesses, including high scattering losses, low resistance to temperature, moisture, lasers and chemicals. Now, SCHOTT has come up with an alternative. The international technology group based in Mainz is now manufacturing diffractive optical elements from optical glass. These elements are extremely precise and efficient and can be manufactured in larger quantities using the precision blank molding technique. More

SOFIA Takes Off With SCHOTT Mirror Substrate
SOFIA (Stratospheric Observatory For Infrared Astronomy), the aircraft-mounted observatory developed by the US space agency NASA (National Aeronautics and Space Administration) and the German Aerospace Center (DLR), was presented to the media in a debut event on June 27, 2007 at Dryden Flight Research Center on Edwards Air Force Base in California. The modified Boeing 747 SP jumbo jet was on show with its high performance infrared telescope built by the German partners. At the heart of the telescope is a 2.7 meter mirror substrate manufactured by the German technology company SCHOTT AG using its “ZERODUR®“ glass ceramic. More

New optical glasses from SCHOTT to reduce volume and weight of optical systems
SCHOTT has expanded its product range by adding two new highly refractive index glass types that address the need for more compact lens systems. The use of highly refractive glasses reduces the monochromatic aberration and allows thinner lenses to be implemented and shorter lens systems to be obtained. Volume and weight of the optical system is reduced, whereas the performance of the optical system does not suffer. More
