An '''excitation filter''' is a high quality optical-glass filter commonly used in [[Fluorescence microscope|fluorescence microscopy]] and [[Spectroscopy|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 <math>E = hc/ \lambda</math>). The excitation filters used may come in 2 main types — '''short pass filters''' and '''band pass filters'''. Variations of these filters exist in the form of '''notch filters''' or deep blocking filters (commonly employed as [[emission filters]]). Other forms of excitation filters include the use of monochromators, wedge prisms coupled with a narrow slit (for selection of the excitation light) and the use of holographic diffraction gratings, etc. [for beam diffraction of white laser light into the required excitation wavelength (selected for by a narrow slit)].
