| Targeted "surgical" filtering | Like an optical scalpel, it deeply truncates only a specific narrow wavelength band (such as a specific laser wavelength), while causing almost no damage to adjacent wavelengths. |
| Broad-spectrum high transmittance | Unlike traditional absorption filters, it has extremely high light energy utilization in non-target wavelength bands, ensuring the overall brightness of imaging or detection. |

What to specify when you request a quote
- Spectral target — state the centre or edge wavelength, the bandwidth and the minimum transmission in the passband.
- Blocking — listed as “Od2 to Od6”; 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 “Customized”; 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 “40/20, 60/40”; quote scratch-dig for imaging paths.
