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).

Design guidance
Three items decide most of the cost and lead time on this work:
- 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.
Application context
Orders for ar coating glass cluster in medical diagnostics (flow cells, slides, microplate bottoms, cuvette windows); microfluidic devices (chips, manifolds, via plates, bonded stacks); mems devices (cap wafers, TGV substrates, motion-sensor lids).

Frequently asked questions
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.
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.
