Claim:
A stereomicroscope fluorescence system for use with a stereomicroscope having two eyepiece receivers for viewing a sample, the stereomicroscope fluorescence system comprising: a light source; an excitation filter adapted to be operably mounted between the light source and the sample; a light guide operably attached to receive light from the light source; and two eyepiece assemblies, each adapted to engage one of the two eyepiece receivers of the stereomicroscope, each eyepiece assembly having at least one eyepiece lens and a barrier filter, the barrier filter being adapted to only allow the fluorescent light from the sample through the eyepiece assembly, wherein each of the eyepiece assemblies includes a housing that includes a first end and a second end, the second end defining an internal chamber shaped to removably receive the barrier filter so that the barrier filter is positioned on the same optical path as the at least one eyepiece lens.
