Fused Silica Glass Plates With Holes – Fused Silica (CTE 0.55 x 10^-6 /K, 185 nm – 2.5 um); Holes 0.15 – 100 mm in plates to 40 mm thick. No minimum order; DFM review included with every RFQ.
We build fused silica glass plates with holes to print – Holes 0.15 – 100 mm in plates to 40 mm thick – primarily in Fused Silica. Typical use: mounting plates, feedthroughs and manifolds.

What the process holds
Beyond this page, Fused Silica routinely runs through double-side polishing, polishing, grinding, drilling in our shop – most real parts combine two or three of these steps.
Production route: drilling, coring, laser cutting – selected per geometry and volume. Edge condition: optional chamfered hole entry.
Specification advice
Before sending the RFQ, check these against your drawing:
- Material note: its hardness and brittleness demand diamond tooling and controlled feeds.
- Hold the controlling dimension (position +/-0.02 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.
Application context
Orders for fused silica glass plates with holes cluster in ccd inspection equipment (CCD cover plates, reference grids, stage glass); laboratory instruments (cuvettes, sight glasses, stir-cell windows); microfluidic devices (chips, manifolds, via plates, bonded stacks).

Frequently asked questions
Is there a minimum order for fused silica glass plates with holes?
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.
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 Fused Silica parts?
Ground features hold +/-0.01 mm and lapped thickness reaches +/-0.003 mm. Its hardness and brittleness demand diamond tooling and controlled feeds.
