Flatness Tolerance for Glass Components: flatness to lambda/8 per 25 mm polished. Single-piece prototypes to production volumes, quoted from your drawing.
flatness tolerance for glass components is a measurable claim, so here is the number: flatness to lambda/8 per 25 mm polished, achieved with interferometer-verified polish and reported against ISO 10110-5 form tolerancing.
Specification envelope
| Held tolerance | flatness to lambda/8 per 25 mm polished |
|---|---|
| Method | interferometer-verified polish |
| Reference standard | ISO 10110-5 form tolerancing |
| RFQ inputs | PDF/DXF/STEP drawing, quantity brackets, surface and edge spec |
Design guidance
Before sending the RFQ, check these against your drawing:
- Cite ISO 10110-5 form tolerancing 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.
The full rules live in our tolerance design guide and holes and edges design guide.
Where these parts end up
flatness tolerance for glass components shows up across laboratory instruments (cuvettes, sight glasses, stir-cell windows); mems devices (cap wafers, TGV substrates, motion-sensor lids); optical sensors (sensor windows, filter caps, lens covers).
If the part is easier to draw than describe, the custom glass machining 3D + 2D builder turns dimensions into an RFQ in a few minutes.

Common questions
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?
ISO 10110-5 form tolerancing, verified by interferometer-verified polish.
Is there a minimum order for flatness tolerance for glass components?
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.
