VIS-NIR LED LIGHT SOURCE: STN-SL1-LED (STELLARNET)

The STN-SL1-LED includes a nose cone assembly with a LED kit consisting of 5 LEDs plus a white LED (390, 470, 502, 590, 660nm and 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, for example: 470nm LED works best for Riboflavin (vitamin D). Other wavelengths can be found more optimal for use with different species chemistry.

Key features:

- 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

Options and Upgrades:

STN-SL1-LED	Miniature fiber optic light source with replaceable LEDs. Includes LED-Kit with set of 6 LEDs: LED-390, LED-470, LED-502, LED-590, LED-660, LED-white. LEDs can be swapped without any wiring changes, just pull one out and push the next one in.
STN-UV-LED KIT	Add on a set of 3 UV LEDs: 295, 345, & 365nm to STN-SL1-LED
STN-UV-LED	1 additional UV LED (choose one between 295, 345, 365, and 390nm) for STN-SL1-LED
STN-SL1-BAT	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 STN-SL1-BAT.
STN-SL1-Blue	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.
