JGS2 Quartz Glass Machining Services – JGS2 Quartz Glass (CTE 0.55 x 10^-6 /K, 220 nm – 2.5 um). No minimum order; DFM review included with every RFQ.
Buyers come to jgs2 quartz glass machining services with two kinds of parts: catalog-adjacent blanks that need accurate finishing, and genuinely custom geometry. We quote both from the same dataset – Optical grade, bubble class 1 stock in 0.20 – 40 mm, blanks to 300 mm diameter.

Beyond this page, JGS2 Quartz Glass routinely runs through lapping, etching, drilling, sandblasting in our shop – most real parts combine two or three of these steps.
Specification advice
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.

Buyer questions, answered
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.
Is there a minimum order for jgs2 quartz glass machining services?
No. Single prototypes are accepted, and pricing steps down at 10, 100 and 1,000 pieces.
How fast can prototypes ship?
Machined prototypes ship in 5 – 10 working days. Coated or bonded parts add 1 – 2 weeks depending on queue slots.
