Block glass


N-BK7 Optical Glass

N-BK7 is an optical bor-crown glass with high optical transmission and a very pure and bright appearance. It is a very high-quality standard material used for any optics. The raw material is in stock as unprocessed glass blocks and requires processing with glass processing techniques. More...


Synthetic Quartz Glass, UV-Grade Fused Silica

Synthetic optical quartz glass offers an excellent UV transmission down to about 180 nm and has a very low expansion coefficient. It is temperature-resistant up to 1000 °C and exceptionally chemically resistant. More...


ULE® Zero Expansion Titania Silicate Glass

ULE® is a transparent glass with an extremely low thermal expansion coefficient, used for high-tech applications in space technology. From ULE®, for example, we can produce length standards, laser resonators, or components for space technology. More...


PYREX® (Code 7740) Borosilicate Glass

PYREX® 7740 is a borosilicate glass composition with good temperature stability and excellent acid resistance. It has a relatively low thermal expansion coefficient and excellent energy transmission from the ultraviolet to the infrared range. More...


VYCOR® (Code 7913)

VYCOR 7913 is a quartz glass substitution material with a 96 % SiO2 content made by CORNING, USA. It has similar properties as natural quartz glass, high optical transmission in the ultraviolet up to the IR, and high chemical resistance. More...


The glasses mentioned above have to be optically processed before they can work as optics. They are ground, polished, and shaped to the customer's specifications, and we can deposit them with an optical coating if required.

We make optical windows, optical substrates, or virtually any other optical component from these glass materials. Please follow the above links to the datasheets of the respective optical glass.


Is the block, drawn, or rolled glass you are looking for not listed above?

If you can't find the optical glass, block-, drawn-, rolled-, or bar-glass you need, please send us an inquiry. We stock and process almost all optical glasses from SCHOTT, CORNING, OHARA, and many other well-known glass manufacturers.
