Fluorescence can be a useful tool in examining geological specimens. While some minerals from particular locations are quite strongly fluorescent, even the weaker fluorescence of other specimens can aid in their detection and identification. The longwave ultraviolet and royal blue excitation wavelength sets of the Stereo Microscope Fluorescence Adapter are particularly useful for examining samples. NIGHTSEA collaborated with a professional geologist in an investigation of the fluorescence of minerals under blue light excitation.

The geology community knows a lot about mineral fluorescence under excitation by various wavelengths of ultraviolet light but when it comes to excitation by light in the visible portion of the spectrum, such as blue, … not so much.
Did you ever wonder how a new piece of equipment comes into existence? The Model SFA arose from a solution to our own marine biology research challenge.
