D263 Thin Glass for Medical Diagnostics: D263 Thin Glass (CTE 7.2 x 10^-6 /K, 350 nm – 2.0 um). Single-piece prototypes to production volumes, quoted from your drawing.
What d263 thin glass for medical diagnostics actually buys from a glass shop: flow cells, slides, microplate bottoms, cuvette windows. The requirement underneath is biocompatible, autoclavable optical components. D263 Thin Glass is the fit here because it offers down-drawn fire-polished surfaces.

Getting the drawing right
Three items decide most of the cost and lead time on this work:
- Material note: ultra-thin stock cannot take conventional clamping; parts are machined on wax or UV-tape carriers.
- 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.
Manufacturing capability
One material, many routes: on D263 Thin Glass we also quote drilling, double-side polishing, edge grinding, grinding, and multi-step drawings are the norm rather than the exception.
Typical applications
The recurring buyers of d263 thin glass for medical diagnostics: medical diagnostics (flow cells, slides, microplate bottoms, cuvette windows); led packaging (groove covers, phosphor carriers, package windows); oled packaging (cover lids, frit-seal frames, fill-port plates).

Common questions
How does D263 Thin Glass behave under heat?
CTE is 7.2 x 10^-6 /K and continuous service reaches 400 C (Tg 557 C), which is what drives its use where down-drawn fire-polished surfaces 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 d263 thin glass 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.
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.
