UV Fused Silica Windows: JGS1, 185 nm – 2.5 um, lambda/8 option. Single-piece prototypes to production volumes, quoted from your drawing.
We supply uv fused silica windows to JGS1, 185 nm – 2.5 um, lambda/8 option – and because we are a machining house first, non-standard outlines, notches and mounting holes are part of the normal order, not an exception.

DFM notes from the shop floor
The shop-floor rules that matter here:
- 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.
Typical applications
The recurring buyers of uv fused silica windows: industrial displays (touch covers, gauge windows, printed bezels); laboratory instruments (cuvettes, sight glasses, stir-cell windows); aerospace optics (sensor windows, star-tracker flats, radiation-tolerant ports).
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
Is there a minimum order for uv fused silica windows?
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.
