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.
Specifications at a glance
| Held tolerance | edge chips < 15 um, chamfer +/-0.05 mm |
|---|---|
| Method | profiled diamond wheels + AOI |
| Reference standard | SEMI edge profile standards |
| RFQ inputs | PDF/DXF/STEP drawing, quantity brackets, surface and edge spec |
Specification advice
Before sending the RFQ, check these against your drawing:
- 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.
Typical applications
Orders for edge tolerance for glass wafers cluster in aerospace optics (sensor windows, star-tracker flats, radiation-tolerant ports); optical sensors (sensor windows, filter caps, lens covers); industrial displays (touch covers, gauge windows, printed bezels).

Buyer questions, answered
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.
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.
