WebThere are basically two types of fluorescence spectroscopy instrument configurations – transmissive and reflective as shown on the figures below. The only real difference between the two is that in the reflective version a dichroic mirror is used to direct the excitation light to the sample and collect the emission light from the sample ... WebIn fluorescence spectroscopy, a beam with a wavelength varying between 180 and ∼800 nm passes through a solution in a cuvette. We then measure – from an angle - the light that is emitted by the sample. In fluorescence spectrometry both an excitation spectrum (the light that is absorbed by the sample) and/or an emission spectrum (the light ...
