PYREX® is a borosilicate glass from CORNING with excellent thermal properties. A low expansion coefficient of only about one-third of that of soda-lime glass materials ensures high thermal shock resistance. PYREX® material has been used to manufacture temperature-resistant optics for a long time.

Unprocessed PYREX® borosilicate glass comes in unpolished large blocks or as rolled sheets. We can grind, polish, and further process these materials to meet customer-specific requirements. |
Glass wafers made of PYREX® are a standard for the semiconductor industry. They are a perfect solution for the anodic bonding of glass to silicon because the thermal expansion of PYREX® borosilicate glass closely matches that of silicon.
A much better chemical resistance than soda-lime materials and exquisite optical transmission over a wide wavelength range made PYREX® a versatile option for many optical applications that were not possible with ordinary soda-lime glass. PYREX® is ground, polished, shaped, and coated according to customer requirements.
PYREX SG3.3
PYREX® rolled sheets and block glass were discontinued many years ago. However, CORNING released PYREX SG3.3 in the meantime, now available in thicknesses of 0.3–2.3 mm. Please send us your inquiry if you are interested in more details about this new PYREX® borosilicate glass version.
Please use the button below to request a quotation for windows, substrates, wafers, or other optics made of PYREX® with individual dimensions.
Please look at our quartz and fused silica materials for higher-temperature requirements. Also we have fused quartz with sight-glass quality available.
Since PYREX® is not available as blank sheet glass, there are no standard thicknesses. The thickness must, therefore, always be specified individually.
Further detailed glass specifications are available on request.
