UV & Visible LED Excitation Sources for SpectroscopySL1-LED Source
UV & Visible LEDs – 390, 470, 502, 590, 660nm, & white available 
Popular Systems: Fluorimetry, UV-VIS Absorbance, Optical Metrology
StellarNet has a variety of UV & Visible LED sources available for spectroscopy applications.
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.
Extensive Life – LEDs have extremely long life.
Flexibility – user replaceable LEDs take less than a few seconds to replace
Small Footprint – only 1.5” x 3” x 3.5” makes it a perfect match for our compact spectrometers
LEDs continually being evaluated and introduced as LED technology improves
Great for fluorescence spectroscopy applications!
Options and Upgrades
UV-LED KIT– Add on a set of UV LEDs for 295, 345, & 365nm
UV-LED – Add on individual UV LEDs. Contact our team for specific wavelength availability
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 pack for the spectrometer and the SL1-BAT.
SL1-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. If you only want one LED permanently installed in similar fashion contact your local representative to discuss further.
