Quick answer: Metallization Glass covers films 50 nm – 2 um, patterned to 10 um lines. Prototypes ship in 5-10 working days.
The point of metallization glass is simple: solderable pads, mirrors and electrodes on glass. We deposit it by sputter + lift-off or shadow mask onto the substrate you specify and verify films 50 nm – 2 um, patterned to 10 um lines on every lot.
The numbers
| Treatment | Metallization – Cr/Au, Ti/Pt or Al thin films |
|---|---|
| Specification | films 50 nm – 2 um, patterned to 10 um lines |
| Deposition / method | sputter + lift-off or shadow mask |
| RFQ inputs | PDF/DXF/STEP drawing, quantity brackets, surface and edge spec |
Specification advice
Three items decide most of the cost and lead time on this work:
- Sequence matters: all machining happens before metallization; post-coating rework is not economical.
- 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
metallization glass shows up across oled packaging (cover lids, frit-seal frames, fill-port plates); scientific instruments (reference flats, cells, prism mounts, stage inserts); optical sensors (sensor windows, filter caps, lens covers).

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.
What does metallization add?
Solderable pads, mirrors and electrodes on glass. Applied by sputter + lift-off or shadow mask to films 50 nm – 2 um, patterned to 10 um lines.
Is there a minimum order for metallization glass?
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.
