What to specify when you request a quote
Diameter and flat / notch — listed as “150mm ± 0.2mm”; state diameter, flat or notch and their tolerances.
Thickness and TTV — listed as “500±25µm”; give thickness, its tolerance and total thickness variation.
Polish and roughness — listed as “Scratch-Dig 40/20”; specify single- or double-side polish and roughness.
Flatness, bow and warp — listed as “≤25µm”; quote flatness, bow and warp limits.
Material grade — listed as “Borosilicate Glass (Borofloat 33)”; name the grade (JGS1/JGS2, Borofloat 33, alkali-free, sapphire orientation).
What is the in Stock 12 Inches 300mm with Notch 0.7mm Thickness Corning Eagle Xg Glass Wafer made of? expand_more
It is listed as Borosilicate Glass (Borofloat 33). Other grades can be quoted if your application needs different transmission, thermal or chemical properties.
What sizes and thicknesses are available? expand_more
The listing gives diameter 150mm ± 0.2mm, thickness 500±25µm. Custom outlines and thicknesses are made to drawing; state the tolerance you need.
What should I include in a quote request? expand_more
Include diameter and flat / notch, thickness and ttv, polish and roughness, flatness, bow and warp and material grade, plus quantity and a drawing if the part is custom.

FREQUENTLY ASKED QUESTIONSWhich fused silica grade should I choose — JGS1, JGS2 or JGS3?
JGS1 offers deep-UV transmission from about 185 nm (best for DUV lithography and UV laser optics). JGS2 transmits well from about 220 nm for standard UV-visible use at lower cost. JGS3 is optimized for visible-to-infrared and high-power laser work. The builder exposes a transmission-band requirement so you can specify the grade by application.
What wafer diameters and thicknesses are supported?
Common diameters are 2, 3, 4 and 6 inch (note 1 inch = 25.0 mm for quartz wafers, so a 4 inch wafer is 100 mm). Typical thicknesses are 200, 500, 700 and 1000 µm, with tighter thickness tolerance and TTV specifiable for polished optical grades.
Can I specify TTV, surface quality and a flat or notch?
Yes. You can set total thickness variation, scratch-dig surface quality (down to 40/20 or 20/10 for optical grade), single- or double-side polish, and a primary flat or notch for orientation.
