Quartz Glass With Through Holes: Quartz Glass (CTE 0.59 x 10^-6 /K, 260 nm – 2.5 um); 0.15 – 100 mm diameter through plates to 40 mm. Single-piece prototypes to production volumes, quoted from your drawing.
Buyers come to quartz glass with through 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: exit-side chipping held under 0.1 mm with backing.
- 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.
Capabilities and limits
One material, many routes: on Quartz Glass we also quote grinding, coring, cnc machining, polishing, and multi-step drawings are the norm rather than the exception.
These features are produced by drilling or coring. Capability: 0.15 – 100 mm diameter through plates to 40 mm. Design rule worth copying onto the drawing: exit-side chipping held under 0.1 mm with backing.

Frequently asked questions
How does Quartz Glass behave under heat?
CTE is 0.59 x 10^-6 /K and continuous service reaches 1,050 C continuous, which is what drives its use where fused from natural quartz crystal matters.
What is the design rule for through holes?
Exit-side chipping held under 0.1 mm with backing.
Is there a minimum order for quartz glass with through 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.
