Sets of LWP and SWP filters offer wavelength coverage over the 400nm to 1000nm spectrum. These filters are quite diverse, and are used in any application requiring the re-direction of a particular band of light. A few such applications are: as trim filters to remove unwanted sideband radiation, color enhancement for maximum contrast in color applications, color combining for photographic use, and as order sorting filters in photometry.
