AR Coating Glass – R < 0.5% per face, 400 – 700 nm (custom bands 193 nm – 2 um). No minimum order; DFM review included with every RFQ.
Specify ar coating glass when the bare substrate falls short: anti-reflective multilayer, processed by ion-assisted e-beam deposition, brings the substrate you specify to R < 0.5% per face, 400 – 700 nm (custom bands 193 nm – 2 um).

DFM notes from the shop floor
Before sending the RFQ, check these against your drawing:
- Sequence matters: all machining happens before ar coating; 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.
The full rules live in our tolerance design guide and holes and edges design guide.
Typical applications
The recurring buyers of ar coating glass: medical diagnostics (flow cells, slides, microplate bottoms, cuvette windows); aerospace optics (sensor windows, star-tracker flats, radiation-tolerant ports); optical sensors (sensor windows, filter caps, lens covers).

Frequently asked 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.
What does ar coating add?
Raises transmission from ~92% to above 99%. Applied by ion-assisted e-beam deposition to R < 0.5% per face, 400 – 700 nm (custom bands 193 nm – 2 um).
Is there a minimum order for ar coating glass?
No. Single prototypes are accepted, and pricing steps down at 10, 100 and 1,000 pieces.
