Fused Silica With Beveled Edges: Fused Silica (CTE 0.55 x 10^-6 /K, 185 nm – 2.5 um); bevel angle 30 – 60 degrees, face width to 5 mm. Single-piece prototypes to production volumes, quoted from your drawing.
Our fused silica with beveled edges cover the full route from blank to inspected part: sawing, CNC profiling, drilling, grinding, polishing and edge finishing under one roof. Fused Silica stands out for near-zero thermal expansion and deep-UV transmission, and both properties survive our processing because every step is tuned to the material.

Getting the drawing right
The shop-floor rules that matter here:
- Material note: its hardness and brittleness demand diamond tooling and controlled feeds.
- Feature rule: polished bevels double as light-guide entry faces.
- 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.
Capabilities and limits
One material, many routes: on Fused Silica we also quote etching, lapping, dicing, double-side polishing, and multi-step drawings are the norm rather than the exception.
These features are produced by edge grinding or polishing. Capability: bevel angle 30 – 60 degrees, face width to 5 mm. Design rule worth copying onto the drawing: polished bevels double as light-guide entry faces.
Who orders this
Orders for fused silica with beveled edges cluster in aerospace optics (sensor windows, star-tracker flats, radiation-tolerant ports); semiconductor equipment (view ports, wafer carriers, plasma rings, chamber windows); microfluidic devices (chips, manifolds, via plates, bonded stacks).

Buyer questions, answered
Is there a minimum order for fused silica with beveled edges?
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.
