StellarNet has a variety of UV-VIS light sources available for spectroscopy applications.
The SL5-DH UV-VIS Light Source is a miniature Deuterium and tungsten halogen light source that covers the 190-2500nm range. The lamp combines the Deuterium Spectrum with the Tungsten Halogen spectrum to form a single optical path. The deuterium and halogen lamps can be individually turned on or off and have a front and rear panel shutter control. The SL5- DH lamp connects via fiber optic cable to cuvette holders, dip probes, and flow cells, with the return signal routed to the spectrometer via SMA 905 input connector.
Dual Lamps & Shutter – The deuterium and halogen lamps can be individually turned on/off and have a front panel shutter control button for taking a quick dark spectra reference. The lamps can also be adjusted for maximum signal.
Miniature Size – Its small size of 1.5 x 2.5 x 6″ makes it a perfect match for our BLUE-Wave or BLACK-Comet spectrometers. A small footprint makes this a great lamp for bench top applications.
Portability – The combination of both lamps into one small enclosure saves money and reduces complexity to provide the ultimate UV-VIS light source for portability. 12VDC power requirements easily allow you to run off our battery pack accessories for hours of field work.
Great for applications that only require low output power like absorbance and transmission measurements
Options and Upgrades
SL5-CUV – adds an external cuvette holder that is ideal for transmission and absorbance measurements for liquids using standard 1cm UV grade cuvettes.
SL5-Filter – adds a nose cone to allow insertion of 0.5 inch diameter UV/VIS/NIR filters for special excitation applications. DCX lens option for x2 signal gain
DCX Lens Upgrade – Lens DCX add-on for 2x gain (SL5-FILTER only)
* Please note the SL5 cannot be used with a reflectance probe as it has low signal power. >> See the SL3 deuterium or SL4 deuterium plus halogen light sources.
