JGS2 Quartz Glass Glass Wafers – JGS2 Quartz Glass (CTE 0.55 x 10^-6 /K, 220 nm – 2.5 um). No minimum order; DFM review included with every RFQ.
A wafer is a specification bundle, not just a disc. jgs2 quartz glass glass wafers here mean Optical grade, bubble class 1 material with certified CTE of 0.55 x 10^-6 /K, TTV controlled per format, and edges profiled for handler compatibility.

Getting the drawing right
The shop-floor rules that matter here:
- Material note: thicker blanks need stress-relief annealing before tight-flatness grinding.
- Over-specification is the quiet budget killer: a 20/10 scratch-dig face costs roughly three times an 80/50 face, so grade each surface individually.
For the complete framework, see the tolerance design guide and the holes and edges design guide.
Manufacturing capability
One material, many routes: on JGS2 Quartz Glass we also quote coring, etching, double-side polishing, polishing, and multi-step drawings are the norm rather than the exception.
Who orders this
jgs2 quartz glass glass wafers shows up across ccd inspection equipment (CCD cover plates, reference grids, stage glass); aerospace optics (sensor windows, star-tracker flats, radiation-tolerant ports); laboratory instruments (cuvettes, sight glasses, stir-cell windows). Background reading on the underlying material science: ScienceDirect: fused quartz.
The fastest route to a quote is geometry: use the 3D builder below, draw a dimensioned 2D drawing from it, or open the site-wide custom glass machining 3D + 2D builder for fully custom parts.
Engineers scoping this work usually also review fused silica wafers 2-12 inch, laser glass cutting, BF33 microfluidic chip.
Common questions
Do parts ship with inspection data?
Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.
What tolerances are achievable on JGS2 Quartz Glass parts?
Ground features hold +/-0.01 mm and lapped thickness reaches +/-0.003 mm. Thicker blanks need stress-relief annealing before tight-flatness grinding.
What thickness range do you stock for JGS2 Quartz Glass?
Standard stock spans 0.20 – 40 mm, with blanks up to 300 mm diameter. Other formats are sourced per order.
How does JGS2 Quartz Glass behave under heat?
CTE is 0.55 x 10^-6 /K and continuous service reaches 1,100 C continuous, which is what drives its use where visible and near-IR clarity matters.
