What to specify when you request a quote
Diameter and flat / notch — listed as “1mm-500mm”; state diameter, flat or notch and their tolerances.
Thickness and TTV — give thickness, its tolerance and total thickness variation.
Polish and roughness — listed as “40/20;60/40”; specify single- or double-side polish and roughness.
Flatness, bow and warp — listed as “1/4 Lambda”; quote flatness, bow and warp limits.
Material grade — listed as “Optical Glass”; name the grade (JGS1/JGS2, Borofloat 33, alkali-free, sapphire orientation).
What is the Synthetic Blue Sapphire Crystal Wafers made of? expand_more
It is listed as Optical Glass. Coating: UV. 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 1mm-500mm. Custom outlines and thicknesses are made to drawing; state the tolerance you need.
What optical or electrical performance does it have? expand_more
Listed values: transmittance >95%. Confirm the values at your operating wavelength, angle and temperature when you request a quote.
Where is this sapphire / specialty wafer used? expand_more
Listed applications: Optical.
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.
