SL3 Deuterium Light Source for UV UV Spectral Range - covers the deep UltraViolet spectral range from 190-450nm. Lifetime – 2000 or 4000 hour performance due to special air flow design and ultra quite fan operation. One of our U.K. customers has reported continuous operation for over a year! Exceptional Performance - designed for maximum stability with precision power control it is ideal for UV spectroscopy. Portability - small size allows for use in field or mobile spectroscopy applications. Worlds smallest long life & high power deuterium light source for CW (continuous wave) UltraViolet for the 190-450nm range. Ø The SL3 Deuterium Light Source - emits a deep UV spectral output over the 190- 450nm range and higher. When using the StellarNet concave grating spectrometers, the SL3 level is good past 550nm. See the comparison graph showing spectral curves from concave grating and CT grating spectrometers. DCX Lens Option - This add-on option increases the deuterium lamp intensity x7 times, and is highly recommended for highly absorbing samples and reflectance measurements. Filter Options - Integrated filter holder fits standard size 0.5 inch diameter disk filters. The U330-filter removes the deuterium spikes seen near 485nm. UV and Vis Light - The optional F400YB fiber optic bundle cable is used to combine the SL1 halogen and SL3 to cover wavelength ranges from 190–2200nm.
