WebThe dichroic filter is placed between the excitation filter and emission filter at a 45° angle and reflects the excitation signal towards the fluorophore while transmitting the emission signal toward the detector. WebWhy fluorescence microscopy uses filters. For epifluorescence microscopes, the excitation filter, dichroic beam-splitter, and emission filter will usually all be housed in the same cube and will be designed to match the spectra of a specific fluorophore or fluorescent protein. Occasionally the filters will not be in a cube, but will be on a wheel, referred to as a turret.
