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.
Specification envelope

| Key tolerance | cutout +/-0.05 mm |
| RFQ inputs | PDF/DXF/STEP drawing, quantity brackets, surface and edge spec |
Manufacturing capability
Production route: cnc machining, laser cutting, ultrasonic machining – selected per geometry and volume. Edge condition: chamfered 0.1 – 0.5 mm as standard.
Getting the drawing right
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.
Who orders this
The recurring buyers of custom glass with internal cutouts: led packaging (groove covers, phosphor carriers, package windows); mems devices (cap wafers, TGV substrates, motion-sensor lids); machine vision (camera windows, ring-light diffusers, calibration plates).
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 beam splitter glass, optical glass options, AR coating process.
Common 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 sizes are available for glass with internal cutouts?
Internal windows with R0.5 mm minimum corner, held to cutout +/-0.05 mm.
