Sheet Glass

High-quality flat glasses for technical applications

On this page, please find information about our technical grade clear flat glass and microsheet materials. Technical sheet glass is fabricated using advanced float-glass processes, or it is directly drawn into glass sheets. It offers a high optical quality that is far beyond what ordinary glass can provide. These glasses are clear and transparent and feature high-grade smooth and mostly fire-polished surfaces, which often give a better flatness, surface quality, and microroughness than a conventional mechanical polishing process could offer. All our sheet glass types are available at various standard thicknesses and with a low nominal glass thickness tolerance. If you are searching for even thinner transparent glass, please take a look at our thin-glass website. We cut and process these materials to any size and shape required. Please follow the links to each datasheet to view the respective specifications and to display the typical optical transmission curves of each of the glass material listed below:

Selected White Float Glass

Our selected float glass is a universal, high-quality, cost-effective flat glass with reduced iron content. It is a technical-grade glass with excellent optical properties. We sort and select this glass for the best surfaces and flatness. The materials are available at 0,40 mm up to 3 mm thickness and as large sheets. More...


BOROFLOAT® Borosilicate Glass

BOROFLOAT® is a technical borosilicate glass material with excellent optical transmittance, outstanding thermal properties, and superb chemical resistance. It is highly transparent in the upper UV-wavelength range at the smaller thicknesses and can be used instead of much more expensive quartz glass in some instances. More...


B 270® - Superwite

The water-white crystal clear crown glass B 270 is a drawn sheet plate glass material with very high purity for universal optical applications. It offers high and steady transmission in the visible and even reaches optical grade after mechanical polishing. More...


1737F Low Alkali Glass

1737F aluminosilicate glass has a virtually alkali-free glass composition. The clear specialty 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 that has a virtually alkali-free material composition. The sheet glass is an ideal choice for AMLCD and COG (chip on glass) applications. It features an outstanding surface quality, excellent flatness, and a low mechanical density. More...


7059 Barium-Borosilicate Glass

7059 is a baria-alumina-borosilicate sheet-glass that contains near zero alkalies. The glass composition offers unique electrical characteristics that are critical for applications in the semiconductor industry. More...


To use our high-grade sheet-glasses for optical applications, they do not even require expensive mechanical polishing processes in most instances because they offer an excellent optical surface quality and flatness by nature. Almost any of the listed transparent glasses can be cut with CNC machines very precisely, resulting in considerable cost savings to the customer's end-product. Nearly all of the listed flat glass types feature a very smooth surface, superior optical flatness, display grade performance, plus a very low micro-roughness, which is often better than what is achievable by a standard optical polishing process. Hence, the glass types in this category are the best choice for many demanding bulk applications. They offer a superior glass grade while keeping the cost control required.


Can't find the technical sheet glass material you are looking for in this overview?

If you cannot find the flat-glass type you are looking for in the list above or need help selecting the appropriate material, please use our inquiry form, send us your inquiry by e-mail, or give us a call. We stock and process many more exotic technical flat glasses that might not be part of the list above.

Note: We do not offer acrylic or other plastic sheets. Those plastic and acrylic sheets often cannot provide the performance usually required for optical applications.
