I dont know anything about "fluorescent microscopi", but I can tell you everything and anything you need to know about Fluorescent Lighting.

 

A fluorescent lamp is actually an electronic device and functions through conduction in gas. The lamps are coated on the inside with a fluorescent chemical, usually of phosphates or magnesiums. The lamps are filled with argon gas, a small drop of mercury, and sealed with electrodes at each end. These electrodes act as cathodes or emitters of electrons within the lamp.

 

The lamps start with a high voltage ballast or starter that first heats the electrodes to begin vaporization of the mercury. Once the electrodes heat up enough (nearly instantly), the circuit is broken and a high voltage arc is created in the mercury-vapor gas that is stabilized by the argon gas. This mercury-vapor arc produces a large amount of ultraviolet-light radiation, which casues the fluorescent chemicals coated on the tube to glow very bright.

 

This is the basic nature of a fluorescent lighting. Is this what you are looking for?
