Quick answer: Custom Special-Shaped Glass covers Any DXF/STEP outline within 600 x 400 mm. Prototypes ship in 5-10 working days.
A drawing for custom special-shaped glass is mostly a conversation about edges and datums. We produce them in fused silica, Borofloat 33, quartz and soda-lime at Any DXF/STEP outline within 600 x 400 mm, with contour +/-0.05 mm as the controlling tolerance, and finish the perimeter per spec.
Specifications at a glance

Capabilities and limits
Production route: cnc machining, laser cutting, edge grinding – selected per geometry and volume. Edge condition: chamfered 0.1 – 0.5 mm as standard.
Design guidance
The shop-floor rules that matter here:
- Hold the controlling dimension (contour +/-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.
Where these parts end up
custom special-shaped glass shows up across scientific instruments (reference flats, cells, prism mounts, stage inserts); machine vision (camera windows, ring-light diffusers, calibration plates); laboratory instruments (cuvettes, sight glasses, stir-cell windows).

Buyer questions, answered
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 special-shaped glass?
Any DXF/STEP outline within 600 x 400 mm, held to contour +/-0.05 mm.
Is there a minimum order for custom special-shaped glass?
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.
