Generally this is done making use of expensive disturbance filters, and the disturbance filters are frequently utilized in combination with expensive dichroic mirrors. Colored glass filters are less costly than disturbance filters, but have much less "sharp" filtering attributes, where a "sharp" filter might have a high slope in the change in transmission or representation as a function of wavelength. Colored glass filters typically have some autofluorescence, where when a filter might be utilized to filter, for instance, an excitation light, the excitation light may produce fluorescence within the filter. Plastic filters usually are very inexpensive, but they normally have a lot more gradual filtering system qualities than tinted glass filters.
