What to specify when you request a quote
- Spectral target — listed as “>95%”; 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 “±2''~±10''”; interference filters shift with angle, so specify the operating angle and cone.
- Size and thickness — listed as “±0.10mm”; give outline, thickness and tolerance, and whether the filter is mounted.
- Substrate — listed as “Optical Glass, Colored Glass”; name the substrate glass if thermal or UV behaviour matters.
- Surface quality — listed as “1/10lambda”; quote scratch-dig for imaging paths.
