An excitation filter is a high quality optical-glass filter commonly used in fluorescence microscopy and spectroscopic applications for selection of the excitation wavelength of light from a light source. Most excitation filters select light of relatively short wavelengths from an excitation light source (as light with shorter wavelengths have higher energy, according to the Planck equation ). The excitation filters used may come in 2 main types - short pass filters and band pass filters.
