The largest solar telescope in the world uses a mirror substrate made of the glass-ceramic ZERODUR® from SCHOTT
The first images from the Daniel K. Inouye Solar Telescope (DKIST) of the National Science Foundation (NSF) were published at the end of January. They show unprecedented details of the sun’s surface and offer a preview of the outstanding results that are expected from this 4-meter solar telescope. This imaging quality is made possible by a monolithic 4.26-meter mirror made of the glass-ceramic ZERODUR®. The huge mirror diameter and the extraordinary material properties make it possible to observe structures on the sun that are 25 kilometers in size, although the sun is almost 150 million kilometers away. This equates to observing a pea from a distance of 30 kilometers. The resolving power is thus 2.6 times higher than that of the largest solar telescope to date, the Big Bear Solar Observatory near Los Angeles, which also uses a primary mirror made of ZERODUR®.More

New ceramic material is a strong enabler for compact laser light applications
The trend of the worldwide lighting solutions market is more and more focusing on laser light. These technologies promise manufacturers applications with superior performance in a smaller package, but also – thanks to innovative materials - to optimize performance and reliability of the light sources. Especially for laser-pumped phosphor light sources, experts from the international technology group SCHOTT have developed unique phosphor ceramic converter assemblies, which offer high irradiance and superior luminance. After its successful launch at the CIOE in China last year, SCHOTT will present an advanced static ceramic converters product line at the SPIE Photonics West in San Francisco, California, Feb. 4- 6, 2020. (South Hall, Booth #841) . Integrated on a heat spreader, they enable innovative, compact light sources without moving parts. During the SPIE Photonics West conference program, Dr. Volker Hagemann, Senior Application Manager Ceramic Converters at SCHOTT, will talk about the product and its impact on laser pumped phosphor light sources used in digital projection and specialty lighting.More
Prominent Augmented Reality (AR) companies join forces to accelerate the journey to consumer-grade AR wearable devices. SCHOTT, Inkron, EV Group (EVG), and WaveOptics present the world's first waveguides made on glass substrate with a refractive index of 1.9 and a matching nanostructured polymer – produced on a 300 mm wafer platform ready for mass production.
SCHOTT, a leading international technology group and the inventor of optical glass, now unveils SCHOTT RealView™ high-index glass wafers with a refractive index of 1.9 and a diameter of 300 mm. These wafers are the basis for high-volume next-generation AR waveguide manufacturing at lower cost per unit, while also maintaining the extremely high precision standards that AR demands. The nanotech company Inkron manufactures the resin that matches the refractive index of 1.9. The resin was used to imprint as many as 24 waveguides on a single 300 mm SCHOTT RealView™ 1.9 wafer using the fully integrated and volume-proven EVG HERCULES® NIL nanoimprint platform. This product combines the glass expertise of SCHOTT and the formulation and resin innovation of Inkron with the standard-setting nanoimprint lithography (NIL) capabilities of EVG by using a renowned waveguide architecture of WaveOptics, the leading optical design house for high-performance waveguides. All companies are united by their aspiration to shape the future of AR. SCHOTT (booth 841), Inkron (booth 5279) and WaveOptics (booth #8 in Demo Hall) will display their parts of the story at the upcoming Photonics West 2020 in San Francisco, Feb. 1-6.More
Glass solutions play a key role in improving LiDAR sensors in self-driving cars
When it comes to autonomous driving, light detection and ranging (LiDAR) technologies are the foundation upon which a next-generation machine vision can be built. LiDAR sensors, together with radar and cameras, will be linked by artificial intelligence (AI) to enable the highest level of advanced driver assistance systems (ADAS 5) and allow for full automation of all driving functions. However, none of the existing LiDAR technologies on the market today meet the performance and reliability requirements to support fully autonomous driving at a competitive price level. SCHOTT is prepared to propel autonomous driving into the future with the broadest range of high-quality glass components and hermetic packaging available to LiDAR manufacturers and suppliers at scale.More

SCHOTT is excited to introduce CONTURAN® Tough AS at the “electronica” trade fair as an alternative for mechanically stressed display glazing.
Two letters, one big difference: AS stands for aluminosilicate glass. With this basic substrate, the SCHOTT technology group is not only expanding its range of anti-reflective CONTURAN® glasses, but also its list of positive properties. CONTURAN® Tough AS is 50 percent more break-resistant than comparable hardened float glass and is thinner and more lightweight. At the electronica trade fair from the 13th to 16th of November 2018 in Munich, display manufacturers can find out more exciting details about the new product (Hall B4, Stand 246).More
In Hamburg’s Elbphilharmonie, television mirror displays produce magical moments utilizing semi-transparent MIRONA®
The curved glass facade of Hamburg’s Elbphilharmonie looks like a massive wave floating 360 feet (110 meters) above the Elbe River. However, glass, a highly adaptable material, has done more than leave a lasting impression on passers-by admiring the concert hall’s exterior architecture. Inside, the semi-transparent MIRONA® glass from SCHOTT brings out surprising reactions: at first, it appears to be a mirror before it magically transforms into an information display.More
Precision material with practically zero expansion
Half a century ago, materials specialists from SCHOTT used an ingenious process technology to develop ZERODUR®, a special glass-ceramic with a coefficient of expansion of nearly zero. This property makes the material ideal for applications requiring the highest precision in fields such as astronomy, IC lithography, the semiconductor industry, metrology, and flat panel display production. In the material’s most recent milestone, the European Southern Observatory (ESO) selected ZERODUR® for the Extremely Large Telescope (ELT) project. SCHOTT will supply the ELT with 798 ZERODUR® blanks including spares to form its primary mirror out of 798 hexagonal tiles and will create its monolithic mirrors with ZERODUR® as well. SCHOTT is currently investing heavily in its glass-ceramic competence center in Mainz. With new melting capacities and post-processing options for a wide range of technical applications, the company is ideally positioned for the future.More

The SCHOTT melting team has started casting the first mirror segments that will make up the 39-meter primary mirror (M-1) of the European Large Telescope (ELT). To make the segments, liquid glass heated to over 1400 degrees Celsius will be poured directly into molds, and transferred into a cooling furnace and subjected to a ceramicization process lasting several weeks. The result is ZERODUR® glass-ceramic, a material with a thermal expansion of near zero that makes it especially suited to astronomy applications. The SCHOTT production facility in Mainz is expected to complete delivery of the segments by 2024.More
