Technical data
| Technical Indicator | Parameter Specification | Indicator Description |
| Dimensional Tolerance | +0.0/-0.2mm | High-precision size control, suitable for automated equipment assembly, reducing assembly gaps |
| Surface Finish | 60-40 | Strict control of surface scratches and pits, stray light suppression rate >98%, improving optical imaging quality |
| Clear Aperture | >90% | High proportion of effective light-transmitting area, avoiding reduced light utilization caused by edge blocking |
| Parallelism | <1 arc min (Angular Minute) | Minimal parallelism error between the two light-transmitting surfaces, reducing optical axis deviation, suitable for high-precision optical systems |
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 “Customize as Per Demand”; state nominal thickness and tolerance; thinner windows need tighter flatness control.
- Surface quality and flatness — 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.
