Mar 04, 2020 · Although dichroic mirrors play a crucial role in fluorescence microscopy, they are not perfect when it comes to blocking unwanted light; typically, ~90% of the light at wavelengths below the cutoff wavelength value are reflected and ~90% of the light at wavelengths above this value are transmitted by the dichroic mirror.

Oct 29, 2020 · The working of fluorescence microscopy is explained below: Firstly a light source falls onto the excitation filter. The function of the excitation filter is to only pass the light of a particular wavelength that can excite the fluorescent molecules tagged the specimen. The excitation light will then fall onto the dichroic mirror.
