Quartz Glass With Microchannels: Quartz Glass (CTE 0.59 x 10^-6 /K, 260 nm – 2.5 um); width from 10 um etched, 100 um machined. Single-piece prototypes to production volumes, quoted from your drawing.
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 microchannels here begin with those numbers and end with dimensional reports.

Manufacturing capability
One material, many routes: on Quartz Glass we also quote polishing, dicing, sandblasting, ultrasonic machining, and multi-step drawings are the norm rather than the exception.
These features are produced by etching or laser cutting. Capability: width from 10 um etched, 100 um machined. Design rule worth copying onto the drawing: isotropic etch widens channels ~2x depth – masks are compensated.
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: isotropic etch widens channels ~2x depth – masks are compensated.
- 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
Is there a minimum order for quartz glass with microchannels?
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.
