> The SLl-Blue is a miniature light source with a very bright 470nm LED installed. A collimating lens is installed just in front of the SMA fiber optic connector output used for fluorescence excitation. > The SL1-LED includes a nose cone assembly with an LED kit consisting of 6 LEDs plus a White LED. LEDs can be swapped without any wiring changes, just pull one out and push the next one in. Each LED can be used to induce fluorescence in many experiments. 470nm LED works best for Riboflavin (vitamin D). Other wavelengths can be found more optimal for use with different species chemistry. > SL1-BAT is a unique option that adds a jack to the SL1 so it can be powered from 5VDC. Users can achieve complete portability with the BP1 battery Spectral Range- LED dependant, optional white. Extensive Life- LEDs have extremely long life. Flexibility- user replaceable LEDs take less than a few Small Footprint- only 1.5" x 3" x 3.5". Maximum Flexibility- Swappable LED option.
