Quick answer: Quartz Glass With Precision Holes covers Quartz Glass (CTE 0.59 x 10^-6 /K, 260 nm – 2.5 um); position +/-0.02 mm, diameter from 0.15 mm. Prototypes ship in 5-10 working days.
When a drawing calls out Quartz Glass, three numbers matter before any machining starts: CTE of 0.59 x 10^-6 /K, service temperature to 1,050 C continuous, and a transmission window of 260 nm – 2.5 um. quartz glass with precision holes here begin with those numbers and end with dimensional reports.

Capabilities and limits
One material, many routes: on Quartz Glass we also quote edge grinding, drilling, grinding, etching, and multi-step drawings are the norm rather than the exception.
These features are produced by drilling or laser cutting. Capability: position +/-0.02 mm, diameter from 0.15 mm. Design rule worth copying onto the drawing: keep hole-to-edge distance above 1.5x thickness.
Getting the drawing right
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: keep hole-to-edge distance above 1.5x thickness.
- 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.

Frequently asked questions
Is there a minimum order for quartz glass with precision 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.
