Fluorescence Microscopy Light Sources

Fluorescence microscopy techniques are now prevalent throughout the life sciences and many of the physical sciences. These techniques are often dependent on white light sources that have evolved from the more traditional mercury arc lamp to metal halide sources to the more recent light emitting diodes (LEDs). The newer light sources show more uniform power across the visible light spectrum, allowing for the use of fluorophores and fluorescent proteins outside of the peak wavelengths associated with the more traditional light sources.
