Quick answer: Fused Silica for Medical Diagnostics covers Fused Silica (CTE 0.55 x 10^-6 /K, 185 nm – 2.5 um). Prototypes ship in 5-10 working days.
fused silica for medical diagnostics programs need biocompatible, autoclavable optical components. Fused Silica is the fit here because it offers near-zero thermal expansion. Typical parts: flow cells, slides, microplate bottoms, cuvette windows.

Manufacturing capability
One material, many routes: on Fused Silica we also quote drilling, edge grinding, grinding, sandblasting, and multi-step drawings are the norm rather than the exception.
Design guidance
Before sending the RFQ, check these against your drawing:
- Material note: its hardness and brittleness demand diamond tooling and controlled feeds.
- 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.
Who orders this
fused silica for medical diagnostics shows up across laser systems (windows, beam splitters, debris shields); ccd inspection equipment (CCD cover plates, reference grids, stage glass); microfluidic devices (chips, manifolds, via plates, bonded stacks). Background reading on the underlying material science: RP Photonics: fused silica.
The fastest route to a quote is geometry: use the 3D builder below, draw a dimensioned 2D drawing from it, or open the site-wide custom glass machining 3D + 2D builder for fully custom parts.

Frequently asked questions
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 do medical diagnostics programs usually order?
Flow cells, slides, microplate bottoms, cuvette windows. Typical spec: USP Class VI compatible processing, no cerium residue.
Is there a minimum order for fused silica for medical diagnostics?
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.
