SL5-CUV SL5 190-2500nm Spectral Range - Combines two light sources into one small package with deuterium bulb plus tungsten-halogen bulb in one fiber optic connection. 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. Dual Lamps - 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. 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. > The SL5 Deuterium Tungsten Halogen Light Source-is a miniature Deuterium and 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. > 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.
