Quick answer: Edge Tolerance for Glass Wafers covers edge chips < 15 um, chamfer +/-0.05 mm. Prototypes ship in 5-10 working days.
edge tolerance for glass wafers is a measurable claim, so here is the number: edge chips < 15 um, chamfer +/-0.05 mm, achieved with profiled diamond wheels + aoi and reported against SEMI edge profile standards.

Getting the drawing right
Three items decide most of the cost and lead time on this work:
- Cite SEMI edge profile standards on the drawing so both sides measure the same way.
- 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.
Application context
The recurring buyers of edge tolerance for glass wafers: medical diagnostics (flow cells, slides, microplate bottoms, cuvette windows); laser systems (windows, beam splitters, debris shields); optical sensors (sensor windows, filter caps, lens covers).

Buyer questions, answered
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.
Which standard governs this?
SEMI edge profile standards, verified by profiled diamond wheels + aoi.
Is there a minimum order for edge tolerance for glass wafers?
No. Single prototypes are accepted, and pricing steps down at 10, 100 and 1,000 pieces.
