JGS1 Quartz Glass Glass Wafers – JGS1 Quartz Glass (CTE 0.55 x 10^-6 /K, 185 nm – 2.5 um (UV grade)). No minimum order; DFM review included with every RFQ.
A wafer is a specification bundle, not just a disc. jgs1 quartz glass glass wafers here mean UV-grade synthetic, bubble class 0 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: UV-grade surfaces must be polished without subsurface damage that scatters below 250 nm.
- 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.
Capabilities and limits
One material, many routes: on JGS1 Quartz Glass we also quote edge grinding, etching, polishing, dicing, and multi-step drawings are the norm rather than the exception.
Typical applications
The recurring buyers of jgs1 quartz glass glass wafers: laser systems (windows, beam splitters, debris shields); aerospace optics (sensor windows, star-tracker flats, radiation-tolerant ports). Background reading on the underlying material science: RP Photonics: fused silica.

Frequently asked 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 JGS1 Quartz Glass parts?
Ground features hold +/-0.01 mm and lapped thickness reaches +/-0.003 mm. UV-grade surfaces must be polished without subsurface damage that scatters below 250 nm.
What thickness range do you stock for JGS1 Quartz Glass?
Standard stock spans 0.10 – 30 mm, with blanks up to 300 mm diameter. Other formats are sourced per order.
How does JGS1 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 deep-UV transmission to 185 nm matters.
Is there a minimum order for jgs1 quartz glass glass wafers?
No. Single prototypes are accepted, and pricing steps down at 10, 100 and 1,000 pieces.
