Custom Glass Frames: Window cutouts with 2 mm minimum web. Single-piece prototypes to production volumes, quoted from your drawing.
A drawing for custom glass frames is mostly a conversation about edges and datums. We produce them in fused silica, Borofloat 33, quartz and soda-lime at Window cutouts with 2 mm minimum web, with cutout +/-0.05 mm as the controlling tolerance, and finish the perimeter per spec.
Key parameters
| Geometry | Glass Frames |
|---|---|
| Size envelope | Window cutouts with 2 mm minimum web |
| Key tolerance | cutout +/-0.05 mm |
| RFQ inputs | PDF/DXF/STEP drawing, quantity brackets, surface and edge spec |
Design guidance
The shop-floor rules that matter here:
- 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.
The full rules live in our tolerance design guide and holes and edges design guide.
Manufacturing capability
Production route: cnc machining, laser cutting – selected per geometry and volume. Edge condition: chamfered 0.1 – 0.5 mm as standard.
Where these parts end up
custom glass frames shows up across laboratory instruments (cuvettes, sight glasses, stir-cell windows); semiconductor equipment (view ports, wafer carriers, plasma rings, chamber windows); microfluidic devices (chips, manifolds, via plates, bonded stacks).

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 sizes are available for glass frames?
Window cutouts with 2 mm minimum web, held to cutout +/-0.05 mm.
Is there a minimum order for custom glass frames?
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.
