What to specify when you request a quote
- Material and grade — 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 — listed as “≤ 550 mm × 250 mm × 8 mm”; give the nominal size and the tolerance you can accept.
- Thickness — state nominal thickness and tolerance; thinner windows need tighter flatness control.
- Surface quality and flatness — listed as “20/10 (Scratch-Dig)”; quote scratch-dig and flatness over the clear aperture, not the whole part.
- Coating — listed as “Dual-Sided Anti-Reflection (Ar) Coating”; list the wavelength band and the maximum reflectance per surface for any AR coating.
- Clear aperture and edges — listed as “< 3"/ Standard Protective Chamfer”; define the usable aperture and the edge chamfer.
