Geology
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.
Fluorescence plays an important role in the analysis of rock cuttings as oil wells are being drilled. Read how a consulting geologist has added the NIGHTSEA system to his toolbag.
NIGHTSEA collaborated with a professional geologist in an investigation of the fluorescence of minerals under blue light excitation.
-
- Norbergite and corundum fluorescence, blue light
-
- Prehnite and pectolite fluorescence. longwave ultraviolet light
-
- Unknown fluorescence observed in scoop of sand from the intertidal zone, California
