What to specify when you request a quote
- Material and grade — listed as “Glass”; name the glass or crystal grade (for example JGS1, N-BK7, Borofloat 33, sapphire) because it fixes the transmission band and thermal limits.
- Diameter or outline — give the nominal size and the tolerance you can accept.
- Thickness — listed as “1mm-2mm”; state nominal thickness and tolerance; thinner windows need tighter flatness control.
- Surface quality and flatness — listed as “as Required”; quote scratch-dig and flatness over the clear aperture, not the whole part.
- Coating — list the wavelength band and the maximum reflectance per surface for any AR coating.
- Clear aperture and edges — define the usable aperture and the edge chamfer.
