Fluorescence filter sets include an Excitation and Emission filter from our TECHSPEC® Fluorescence Bandpass Filters and a Dichroic filter from our TECHSPEC® Dichroic Filters. Excitation filters are placed within the illumination path of fluorescence microscopes to pass only wavelengths within the excitation range of the fluorophore under inspection. Emission filters are placed within the imaging path of a fluorescence microscope to pass only wavelengths within the emission range of the fluorophore. Dichroic filters are placed in between the excitation filter and the emission filter to reflect the excitation signal towards the fluorophore while transmitting the emission signal to the detector.
Filter sets are listed with the most common fluorophores. For a full list of compatible fluorophores with each set, view Fluorophores and Optical Filters for Fluorescence Microscopy. TECHSPEC Fluorescence Filter Sets are available pre-mounted in Olympus or Nikon Filter Cubes.
