Fused Silica With Edge Notches: Fused Silica (CTE 0.55 x 10^-6 /K, 185 nm – 2.5 um); notch width from 0.5 mm, positioned +/-0.05 mm. Single-piece prototypes to production volumes, quoted from your drawing.
Our fused silica with edge notches 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.

Design guidance
Three items decide most of the cost and lead time on this work:
- Material note: its hardness and brittleness demand diamond tooling and controlled feeds.
- Feature rule: radius every internal notch corner – sharp corners crack.
- 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.
Manufacturing capability
One material, many routes: on Fused Silica we also quote drilling, cnc machining, lapping, ultrasonic machining, and multi-step drawings are the norm rather than the exception.
These features are produced by cnc machining or laser cutting. Capability: notch width from 0.5 mm, positioned +/-0.05 mm. Design rule worth copying onto the drawing: radius every internal notch corner – sharp corners crack.
Typical applications
Orders for fused silica with edge notches cluster in ccd inspection equipment (CCD cover plates, reference grids, stage glass); optical sensors (sensor windows, filter caps, lens covers); medical diagnostics (flow cells, slides, microplate bottoms, cuvette windows).

Buyer questions, answered
How does Fused Silica behave under heat?
CTE is 0.55 x 10^-6 /K and continuous service reaches 1,100 C continuous, which is what drives its use where near-zero thermal expansion matters.
What is the design rule for edge notches?
Radius every internal notch corner – sharp corners crack.
Is there a minimum order for fused silica with edge notches?
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.
