Technical-grade Sheet Glass

High quality flat glass and plate glass

Sheet glass, flat glass and plate glass materials are either fabricated by using the float-glass process, or they are drawn to sheets. They are usually clear and transparent and feature fire polished surfaces. All our sheet glasses are available at various standard thicknesses with low nominal thickness tolerances. For most applications, our technical grade sheet glass doesn't even require an additional polishing process to be used for an optical application. Most of these transparent glasses can be CNC-cut very precisely, which is resulting in considerable cost savings to the customer and lower cost of the end product. Almost all the listed technical quality flat glass types feature a very smooth surface, a good optical flatness, a display grade quality plus a low micro roughness. Especially the micro roughness of sheet glass often is better than what can be achieved by a standard mechanical polishing process. Some materials shown in this category are the best choice for bulk productions. They offer both, a superior glass quality and the cost control required. Below, please find the links to our technical grade sheet glass types that are part of our extensive glass delivery program. Just follow the links to the respective data-sheets to see the specifications and to view the typical transmission curves of each sheet glass below:


Sheet glass windows


Selected White Float Glass

Universal, low-cost quality flat sheet glass. Technical glass with good optical properties.

BOROFLOAT® Borosilicate Glass

Clear appearing technical glass material with very good optical transmittance, great thermal resistance plus very good chemical properties. Highly transparent even in the upper UV. Large sheets are available.


Very clear drawn technical optical sheet glass with very good performance and purity for universal optical use.

1737F Low Alkali Glass

Virtually alkali-free aluminosilicate glass composition. Technical glass, that for example can withstand the rigorous thermal cycles of poly-silicate transistor processes. Replacement- and successor material for 7059F sheet glass.

EAGLE2000 Lightweight Low Alkali Glass

Lightweight, virtually alkali-free material with an alkaline earth boro-aluminosilicate glass composition. Technical glass for AMLCD and COG (chip on glass) applications, with a very good surface quality and good flatness.

7059, 7059F Barium-Borosilicate Glass

Near-zero-alkali baria alumina borosilicate glass sheets. Technical glass composition with special electrical characteristics.
