High Quality Sheet-Glass

Specialty flat glasses for technical use

On this page you will find information about our technical grade flat glass and microsheet materials. Sheet-glass materials are fabricated by using advanced float-glass processes or they are drawn into glass-sheets. They offer a high optical quality that is far beyond what normal glass can offer. The materials are clear and transparent and feature high grade smooth and mostly fire-polished surfaces. All our sheet glass types are available at various standard thicknesses and with a low nominal glass thickness tolerance. If you are in search for even thinner transparent glass materials please take a look on our thin glass web site. Please follow the links to each data-sheet to view the respective specifications and to display the typical optical transmission curves of each of the glass materials listed below:

Selected White Float Glass

Our selected float glass is a universal high quality low-cost flat sheet glass with a reduced iron content. It is a technical grade glass with very good optical properties. We sort and select this glass for best surface quality and flatness. The glass is available at 0,40 mm up to 3 mm thickness. more...


BOROFLOAT® Borosilicate Glass

BOROFLOAT® is a clear and highly transparent technical borosilicate glass material with very good optical transmittance, great thermal properties, plus a very good chemical resistance. It even is highly transparent in the upper UV-wavelength range. more...


B 270® - Superwite

The very clear crown glass B 270 is a drawn sheet glass material with a very high purity used for universal optical applications. It offers a high and steady transmission in the visible and reaches optical quality after mechanical polishing. more...


1737F Low Alkali Glass

1737F aluminosilicate glass has a virtually alkali-free glass composition. The technical glass can withstand the rigorous thermal cycles of poly-silicate transistor processes. Hence, it is often used for semiconductor applications. It is the replacement- and successor material for the display sheet glass 7059F. more...


EAGLE2000 Lightweight Low Alkali Glass

EAGLE2000 is a lightweight alkaline earth boro-aluminosilicate glass which has a virtually alkali-free material composition. The technical glass is often used for AMLCD and COG (chip on glass) applications. It features a very good surface quality and a good flatness. more...


7059 Barium-Borosilicate Glass

7059 is a baria-alumina-borosilicate sheet-glass that contains near zero alkali. The glass composition offers special electrical characteristics required in the semi-conductor industry. more...



In order to use our high quality sheet-glass for optical applications in most instances these glass types often do not even require an additional expensive mechanical polishing process because most of them offer an excellent natural surface quality and flatness. Almost any of these transparent glasses can be cut with CNC-machines very precisely which is resulting in considerable cost savings to the customer and therefore lower the cost of the end-product. Nearly all of the listed flat glass types with technical quality feature a very smooth surface, a good optical flatness, display grade surface quality, plus a very low micro roughness. The micro roughness of these glasses is often better than what is achievable by a standard optical polishing finish. Hence, the glass types in this category are the best choice for many demanding applications at large production series. They offer both, a superior glass quality while keeping the cost control required.
