What to specify when you request a quote
- Spectral target — listed as “8-32nm”; state the centre or edge wavelength, the bandwidth and the minimum transmission in the passband.
- Blocking — listed as “Od2-Od6”; give the blocking range and optical density (OD) the system needs.
- Angle of incidence — listed as “45°”; interference filters shift with angle, so specify the operating angle and cone.
- Size and thickness — listed as “0.3-4.0mm”; give outline, thickness and tolerance, and whether the filter is mounted.
- Substrate — listed as “K9, Bk7, B270, D263t, Fused Silica, Quartz Glass”; name the substrate glass if thermal or UV behaviour matters.
- Surface quality — listed as “40-20”; quote scratch-dig for imaging paths.
