Laser Cutting JGS2 Quartz Glass: JGS2 Quartz Glass (CTE 0.55 x 10^-6 /K, 220 nm – 2.5 um); Laser Cutting to +/-0.02 mm contour. Single-piece prototypes to production volumes, quoted from your drawing.
laser cutting jgs2 quartz glass is a materials problem before it is a machining problem. JGS2 Quartz Glass has visible and near-ir clarity and a Knoop hardness of 500 kg/mm2, so the laser cutting recipe – feeds, coolant, tooling – differs from what works on ordinary float glass. The line runs picosecond and CO2 laser stations with vision registration and holds +/-0.02 mm contour.

DFM notes from the shop floor
Before sending the RFQ, check these against your drawing:
- Material note: thicker blanks need stress-relief annealing before tight-flatness grinding.
- Process boundary: aspect ratio in a single pass tops out near 10:1; thicker sections shift to coring or ultrasonic work.
- 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.
The full rules live in our tolerance design guide and holes and edges design guide.
Manufacturing capability
The core strength of Laser Cutting is chip-free free-form contours and dense hole arrays in thin and ultra-thin glass. The honest limit: aspect ratio in a single pass tops out near 10:1; thicker sections shift to coring or ultrasonic work. Both belong on the drawing before quoting, not after.
One material, many routes: on JGS2 Quartz Glass we also quote dicing, sandblasting, lapping, edge grinding, and multi-step drawings are the norm rather than the exception.

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.
What accuracy does laser cutting hold?
+/-0.02 mm contour with minimum features of 0.10 mm hole diameter. Aspect ratio in a single pass tops out near 10:1; thicker sections shift to coring or ultrasonic work.
What equipment runs the laser cutting work?
Picosecond and CO2 laser stations with vision registration.
