Laser Cutting D263 Thin Glass – D263 Thin Glass (CTE 7.2 x 10^-6 /K, 350 nm – 2.0 um); Laser Cutting to +/-0.02 mm contour. No minimum order; DFM review included with every RFQ.
We laser-cut D263 Thin Glass daily, in thicknesses from 0.03 – 6 mm. The controlling numbers: +/-0.02 mm contour working tolerance, 0.10 mm hole diameter minimum features, and sealed edge, chip-free off the machine. Where the drawing asks for more, downstream lapping and polishing take over.

Capabilities and limits
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 D263 Thin Glass we also quote edge grinding, drilling, double-side polishing, cnc machining, and multi-step drawings are the norm rather than the exception.
Specification advice
Before sending the RFQ, check these against your drawing:
- Material note: ultra-thin stock cannot take conventional clamping; parts are machined on wax or UV-tape carriers.
- 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.
For the complete framework, see the tolerance design guide and the holes and edges design guide.

Buyer questions, answered
What tolerances are achievable on D263 Thin Glass parts?
Ground features hold +/-0.01 mm and lapped thickness reaches +/-0.003 mm. Ultra-thin stock cannot take conventional clamping; parts are machined on wax or UV-tape carriers.
What thickness range do you stock for D263 Thin Glass?
Standard stock spans 0.03 – 1.1 mm, with blanks up to 440 x 360 mm. Other formats are sourced per order.
How does D263 Thin Glass behave under heat?
CTE is 7.2 x 10^-6 /K and continuous service reaches 400 C (Tg 557 C), which is what drives its use where down-drawn fire-polished surfaces 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.
