Custom Glass With Internal Cutouts: Internal windows with R0.5 mm minimum corner. Single-piece prototypes to production volumes, quoted from your drawing.
custom glass with internal cutouts are ordered for display apertures and multi-window panels. The geometry envelope is Internal windows with R0.5 mm minimum corner, held to cutout +/-0.05 mm, in fused silica, Borofloat 33, quartz and soda-lime.

Capabilities and limits
Production route: cnc machining, laser cutting, ultrasonic machining – selected per geometry and volume. Edge condition: chamfered 0.1 – 0.5 mm as standard.
Specification advice
Three items decide most of the cost and lead time on this work:
- Hold the controlling dimension (cutout +/-0.05 mm) and let secondary dimensions carry standard tolerance – it is the single biggest cost lever.
- 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.
Where these parts end up
The recurring buyers of custom glass with internal cutouts: scientific instruments (reference flats, cells, prism mounts, stage inserts); machine vision (camera windows, ring-light diffusers, calibration plates); industrial displays (touch covers, gauge windows, printed bezels).
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.

Common 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 sizes are available for glass with internal cutouts?
Internal windows with R0.5 mm minimum corner, held to cutout +/-0.05 mm.
Is there a minimum order for custom glass with internal cutouts?
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.
