What to specify when you request a quote
- Spectral target — listed as “Per Customer Spec (Tbd)”; 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 — interference filters shift with angle, so specify the operating angle and cone.
- Size and thickness — give outline, thickness and tolerance, and whether the filter is mounted.
- Substrate — listed as “Fused Silica”; name the substrate glass if thermal or UV behaviour matters.
- Surface quality — listed as “20-10 Scratch-Dig”; quote scratch-dig for imaging paths.
