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.

Capabilities and limits
One material, many routes: on Quartz Glass we also quote sandblasting, grinding, edge grinding, drilling, 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.
Specification advice
Before sending the RFQ, check these against your drawing:
- 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
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 microchannels?
Isotropic etch widens channels ~2x depth – masks are compensated.
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.
