## What to specify when you request a quote

- **Spectral target** — listed as “355-1064nm”; 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 “45°”; interference filters shift with angle, so specify the operating angle and cone.
- **Size and thickness** — listed as “±0.1mm”; 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** — quote scratch-dig for imaging paths.
