Scratch-Dig Requirements for Optical Glass: 80/50 commercial to 10/5 precision. Single-piece prototypes to production volumes, quoted from your drawing.
Drawings fail at the tolerance block more than anywhere else. For scratch-dig requirements for optical glass the achievable envelope is 80/50 commercial to 10/5 precision – the method is mil-prf-13830b visual comparison.
Key parameters
| Held tolerance | 80/50 commercial to 10/5 precision |
|---|---|
| Method | MIL-PRF-13830B visual comparison |
| Reference standard | MIL-PRF-13830B / ISO 10110-7 |
| RFQ inputs | PDF/DXF/STEP drawing, quantity brackets, surface and edge spec |
Design guidance
Three items decide most of the cost and lead time on this work:
- Cite MIL-PRF-13830B / ISO 10110-7 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.
Typical applications
scratch-dig requirements for optical glass shows up across aerospace optics (sensor windows, star-tracker flats, radiation-tolerant ports); industrial displays (touch covers, gauge windows, printed bezels); microfluidic devices (chips, manifolds, via plates, bonded stacks).

Common questions
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?
MIL-PRF-13830B / ISO 10110-7, verified by mil-prf-13830b visual comparison.
Is there a minimum order for scratch-dig requirements for optical glass?
No. Single prototypes are accepted, and pricing steps down at 10, 100 and 1,000 pieces.
