Quartz Glass With Micro Holes: Quartz Glass (CTE 0.59 x 10^-6 /K, 260 nm – 2.5 um); diameter 0.10 – 0.5 mm, arrays past 10,000 holes. Single-piece prototypes to production volumes, quoted from your drawing.
Buyers come to quartz glass with micro holes with two kinds of parts: catalog-adjacent blanks that need accurate finishing, and genuinely custom geometry. We quote both from the same dataset – GE214-equivalent, semiconductor grade stock in 0.20 – 60 mm, blanks to 450 mm diameter.

Design guidance
The shop-floor rules that matter here:
- Material note: natural-quartz batches vary in metallic ppm, so semiconductor lots need certs per melt.
- Feature rule: aspect ratio to 10:1 in a single laser pass.
- 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.
Process window
Beyond this page, Quartz Glass routinely runs through lapping, edge grinding, ultrasonic machining, coring in our shop – most real parts combine two or three of these steps.
These features are produced by laser cutting or etching. Capability: diameter 0.10 – 0.5 mm, arrays past 10,000 holes. Design rule worth copying onto the drawing: aspect ratio to 10:1 in a single laser pass.

Frequently asked questions
Is there a minimum order for quartz glass with micro holes?
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.
What files do you need for a quote?
A dimensioned PDF plus DXF or STEP geometry. If only a sketch exists, our drawing review service formalizes it before quoting.
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 Quartz Glass parts?
Ground features hold +/-0.01 mm and lapped thickness reaches +/-0.003 mm. Natural-quartz batches vary in metallic ppm, so semiconductor lots need certs per melt.
