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
- Spectral target — listed as “T>90%”; state the centre or edge wavelength, the bandwidth and the minimum transmission in the passband.
- Blocking — give the blocking range and optical density (OD) the system needs.
- Angle of incidence — listed as “0°”; interference filters shift with angle, so specify the operating angle and cone.
- Size and thickness — listed as “100mm”; give outline, thickness and tolerance, and whether the filter is mounted.
- Substrate — listed as “Glass”; name the substrate glass if thermal or UV behaviour matters.
- Surface quality — listed as “60/40”; quote scratch-dig for imaging paths.
