The Desmid Micrasterias thomasiana.
This microbe is a green algae found in acidic water. I illuminated it with light of a short wavelength (UV 360 nm ) which is absorbed by the molecular structure of the cell, and which is then re-radiated at longer wavelengths , namely, red light. Several filters are needed in order to form barriers against the UV radiation. Fluorescence microscopy works well on green algae. Steve Durr.
