AR Coating JGS1 Quartz Glass – JGS1 Quartz Glass (CTE 0.55 x 10^-6 /K, 185 nm – 2.5 um (UV grade)); R < 0.5% per face, 400 – 700 nm (custom bands 193 nm – 2 um). No minimum order; DFM review included with every RFQ.
Specify ar coating jgs1 quartz glass when the bare substrate falls short: anti-reflective multilayer, processed by ion-assisted e-beam deposition, brings JGS1 Quartz Glass to R < 0.5% per face, 400 – 700 nm (custom bands 193 nm – 2 um).

Process window
Beyond this page, JGS1 Quartz Glass routinely runs through etching, lapping, dicing, double-side polishing in our shop – most real parts combine two or three of these steps.
Getting the drawing right
The shop-floor rules that matter here:
- Material note: UV-grade surfaces must be polished without subsurface damage that scatters below 250 nm.
- Sequence matters: all machining happens before ar coating; post-coating rework is not economical.
- 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.

Frequently asked questions
Is there a minimum order for ar coating jgs1 quartz glass?
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.
