Optical filters

Filters with a bandwidth up to 5% of the center wavelength

Filters with a bandwidth of 5% to 10% of the center wavelength

Filters with a bandwidth greater than 10% of the center wavelength

Long/Shortpass cutoff filters

Filters with a given level of optical density in a wide range

Inverse bandpass filter

Several filters combined on the same substrate, but separated into separate zones

Multiple bandwidths in a single coverage

Filters whose spectral properties change linearly
