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® rolled sheets and block glass were discontinued for many years. However, CORNING recently released PYREX SG3.3, 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® version.
Please consider using the button below to request a quotation for windows, substrates, wafers, or other optics made of PYREX® with individual dimensions.
Since PYREX® is not available as blank sheet glass, there are no standard thicknesses. The thickness must, therefore, always be specified individually.
