Ultraviolet Light Head for the SFA

The Ultraviolet light head for the Stereo Microscope Fluorescence Adapter uses an LED that excites in the 360-380nm range and is combined with a UV-transparent focusing lens and a supplementary filter to eliminate any visible light interference. It is paired with a UV-blocking barrier filter and viewing shield.

Here are some examples of stereo microscope images made with the UV light-filter combination.
