ITO Coated Glass Machining Services – ITO Coated Glass (CTE substrate dependent, >85% visible @ 100 ohm/sq). No minimum order; DFM review included with every RFQ.
When a drawing calls out ITO Coated Glass, three numbers matter before any machining starts: CTE of substrate dependent, service temperature to 350 C (coating stable), and a transmission window of >85% visible @ 100 ohm/sq. ito coated glass machining services here begin with those numbers and end with dimensional reports.

Process window
Beyond this page, ITO Coated Glass routinely runs through coring, cnc machining, edge grinding, dicing in our shop – most real parts combine two or three of these steps.
Specification advice
Three items decide most of the cost and lead time on this work:
- Material note: machining happens film-side-aware: scribing, edge deletion and contact zones are defined before cutting.
- 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.
Who orders this
Orders for ito coated glass machining services cluster in laser systems (windows, beam splitters, debris shields); machine vision (camera windows, ring-light diffusers, calibration plates); optical sensors (sensor windows, filter caps, lens covers). Background reading on the underlying material science: ScienceDirect: indium tin oxide.
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.

Buyer questions, answered
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 tolerances are achievable on ITO Coated Glass parts?
Ground features hold +/-0.01 mm and lapped thickness reaches +/-0.003 mm. Machining happens film-side-aware: scribing, edge deletion and contact zones are defined before cutting.
