What is a dual monochromator spectrofluorometer system?
Some fluorescence microplate readers use dual monochromators instead of filters to select the wavelength of light that excites the sample, as well as the wavelength that is emitted by the sample. Monochromators use a diffraction grating to spatially separate the colors of light and can select a wide range of wavelengths without the need to install a separate filter for each wavelength required by an application.
Our SpectraMax Gemini dual-monochromator spectrofluorometer uses two scanning monochromators for selection of the optimal excitation and emission wavelengths.
