What if my part does not match any standard builder?

Use the custom glass builder: choose shape (including ring or drawing-defined), size, thickness, optional holes, coating and edge/surface finish, set a tolerance, preview it in 3D and attach a drawing to the RFQ.

Which materials can the custom builder use?

Fused silica, quartz, JGS1/JGS2, Borofloat 33, alkali-free and borosilicate glass, optical and soda-lime glass, or a named custom material such as sapphire or Zerodur.
