BANDPASS FILTERS block all but a particular wavelength. The width of such a filter is expressed in the wavelength range it lets through and can be anything from much less Angstrom to a few hundred nanometers.

A SHORTPASS FILTER is an optical interference or colored glass filter. It attentuates longer wavelengths and transmits (passes) shorter wavelengths over the active range of the target spectrum (usually the ultraviolet or visible region).

A LONGPASS FILTER is an optical interference or colored glass filter. It attenuates shorter wavelengths and transmits (passes) longer wavelengths over the active range of the target spectrum (ultraviolet, visible, or infrared).

NEUTRAL DENSITY FILTERS have a constant attenuation across the range of visible wavelengths, and are used to reduce the intensity of light by reflecting or absorbing a portion of it.

A NOTCH FILTER is a filter that passes all frequencies except those in a stop band centered on a center frequency.
