Light diffraction device for separating excitation and emission light in confocal microscope e.g. laser scanning microscope, uses at least one diffraction element for diffraction of selected wavelength of excitation light
Light diffraction device for separating excitation and emission light in confocal microscope e.g. laser scanning microscope, uses at least one diffraction element for diffraction of selected wavelength of excitation light
The light diffraction device uses at least one light diffraction element, e.g. an acousto-optical tunable filter (AOTF), inserted in the light path of both the excitation and the emission beams in a confocal microscope, for selective diffraction of at least one selected wavelength of the excitation beam, the emission light passing through the diffraction element without being affected.
