Min FWHM     Max FWHM     

Note, for cut-on, cut-off and multi pass band (GG385 UG1) filters the FWHM has been set to 0. The Cenwave indicates the blue peak of the UG1 and GG375 filters and the cut wavelength for the rest of these filters.

Sort by clicking the column title, e.g. click on Cenwave to order the filters from blue to red
