An elegant and economical way to add fluorescence to stereo microscopes for evidence examination. I love it!
– Skip Palenik, Microtrace
The NIGHTSEA Model SFA Stereo Microscope Fluorescence Adapter is an economical way to turn any existing stereo microscope into a go-to tool for screening trace evidence. Not everything has fluorescence, but when it is present it can make all the difference in detection. You can’t analyze something until you find it, and fluorescence can help in that critical step. The SFA makes it easy to add this method to your suite of screening tools.

Trade-offs between the longpass and bandpass (green-only) filters for use with the Royal Blue excitation.
There are two types of approaches to answering the question of whether something fluoresces – empirical (try it and see) vs scientific (make careful measurements). Read to learn the difference.
Fluorescence microscopy imaging trials with the NIGHTSEA Model SFA and Unitron and Zeiss microscopes with digital cameras.
With fluorescence, what you see depends on how you excite and view the subject – the interaction of the excitation wavelength, the fluorescing substance, and the barrier filter.
