Fused Silica Perforated Glass Plates: Fused Silica (CTE 0.55 x 10^-6 /K, 185 nm – 2.5 um); Hole grids from 0.15 mm diameter, pitch from 0.5 mm. Single-piece prototypes to production volumes, quoted from your drawing.
A drawing for fused silica perforated glass plates is mostly a conversation about edges and datums. We produce them in Fused Silica at Hole grids from 0.15 mm diameter, pitch from 0.5 mm, with hole position +/-0.02 mm as the controlling tolerance, and finish the perimeter per spec.

Specification advice
Three items decide most of the cost and lead time on this work:
- Material note: its hardness and brittleness demand diamond tooling and controlled feeds.
- Hold the controlling dimension (hole 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.
What the process holds
Beyond this page, Fused Silica routinely runs through polishing, etching, edge grinding, sandblasting in our shop – most real parts combine two or three of these steps.
Production route: drilling, laser cutting, ultrasonic machining – selected per geometry and volume. Edge condition: optional chamfered hole entry.
Typical applications
fused silica perforated glass plates shows up across optical sensors (sensor windows, filter caps, lens covers); mems devices (cap wafers, TGV substrates, motion-sensor lids); aerospace optics (sensor windows, star-tracker flats, radiation-tolerant ports).

Common questions
Is there a minimum order for fused silica perforated glass plates?
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.
