Manufacturing capability
One material, many routes: on JGS1 Quartz Glass we also quote etching, grinding, laser cutting, lapping, and multi-step drawings are the norm rather than the exception.
DFM notes from the shop floor
Before sending the RFQ, check these against your drawing:
- Material note: UV-grade surfaces must be polished without subsurface damage that scatters below 250 nm.
- 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.

Frequently asked questions
How does JGS1 Quartz Glass 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 deep-UV transmission to 185 nm matters.
What do aerospace optics programs usually order?
Sensor windows, star-tracker flats, radiation-tolerant ports. Typical spec: fused silica preferred, full material certs.
Is there a minimum order for jgs1 quartz glass for aerospace optics?
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.
