AR Coated Optical Windows – R < 0.5% per face, custom bands, 20/10 surfaces. No minimum order; DFM review included with every RFQ.
We supply ar coated optical windows to R < 0.5% per face, custom bands, 20/10 surfaces – and because we are a machining house first, non-standard outlines, notches and mounting holes are part of the normal order, not an exception.
The numbers
| Optical specification | R < 0.5% per face, custom bands, 20/10 surfaces |
|---|---|
| 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:
- 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
The recurring buyers of ar coated optical windows: machine vision (camera windows, ring-light diffusers, calibration plates); optical sensors (sensor windows, filter caps, lens covers); mems devices (cap wafers, TGV substrates, motion-sensor lids).
The fastest route to a quote is geometry: use the 3D builder below, draw a dimensioned 2D drawing from it, or open the site-wide custom glass machining 3D + 2D builder for fully custom parts.
Engineers scoping this work usually also review infrared windows, precision glass grinding, glass-bottom microplates.
Common questions
Is there a minimum order for ar coated optical windows?
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.
Do parts ship with inspection data?
Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.
