Fused Silica With Grooves – Fused Silica (CTE 0.55 x 10^-6 /K, 185 nm – 2.5 um); depth from 0.2 mm, V, U or square section. No minimum order; DFM review included with every RFQ.
Buyers come to fused silica with grooves with two kinds of parts: catalog-adjacent blanks that need accurate finishing, and genuinely custom geometry. We quote both from the same dataset – JGS1 (UV), JGS2 (standard), JGS3 (IR) stock in 0.10 – 50 mm, blanks to 450 x 450 mm.

Getting the drawing right
Before sending the RFQ, check these against your drawing:
- Material note: its hardness and brittleness demand diamond tooling and controlled feeds.
- Feature rule: depth under 50% of thickness preserves strength.
- 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 drilling, double-side polishing, edge grinding, laser cutting in our shop – most real parts combine two or three of these steps.
These features are produced by cnc machining or ultrasonic machining. Capability: depth from 0.2 mm, V, U or square section. Design rule worth copying onto the drawing: depth under 50% of thickness preserves strength.
Where these parts end up
Orders for fused silica with grooves cluster in medical diagnostics (flow cells, slides, microplate bottoms, cuvette windows); machine vision (camera windows, ring-light diffusers, calibration plates); mems devices (cap wafers, TGV substrates, motion-sensor lids).

Buyer questions, answered
How does Fused Silica behave under heat?
CTE is 0.55 x 10^-6 /K and continuous service reaches 1,100 C continuous, which is what drives its use where near-zero thermal expansion matters.
What is the design rule for grooves?
Depth under 50% of thickness preserves strength.
Is there a minimum order for fused silica with grooves?
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.
