What to specify when you request a quote
- Spectral target — listed as “200-1000nm,AOI:0deg”; state the centre or edge wavelength, the bandwidth and the minimum transmission in the passband.
- Blocking — listed as “2.8OD”; 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 “18.0+0.0/-0.3mm”; 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.
