SL4-DT Deuterium & Tungsten Light for UV-VIS-NIR • • Dual Lamps – Shutter button on the front panel blocks the light output of both lamps, necessary for taking dark reference spectrums without turning off the source. • Portability - The combination of both lamps into one small enclosure reduces complexity and can be connected to the BP2 battery pack for field applications. SL4-DT Deuterium & Tungsten Light is a miniature Deuterium and Tungstenhalogen light source that covers the 2001700nm range in a single light source for spectroscopy measurements. It’s high output power enables use for reflectance measurements, where other low power light sources like SL5-DT are too weak. • D-alpha line (654nm) eliminated in deuterium source. • • 200-1700nm Spectral Range - Combines two light sources into one small package with Deuterium bulb plus Tungsten-halogen bulb that has one SMA 905 fiber optic connection. Miniature Size - Small size of 72 mm x 40 mm x 90 mm makes it a perfect match for StellarNet miniature spectrometers: Concave 190-850nm & CSR 220-1100nm EPP2000-UVN-SR 200-1100nm GREEN-Wave UVNb 200-1050nm BLUE-Wave UVNb 200-1050nm Item SL4-DT SL4-B-UV SL4-B-VIS Paper, leaf, powder, and rock spectra obtained with the SL4-DT and concave grating spectrometer Description High output Deuterium/Tungsten Lamp for UV-VIS Deuteruim replacement bulb for UV Halogen replacement bulb for VIS Weight Power consumption Spectral Range Time to stabilize output Optical power in Watts/m2 VIS Bulb Color Temp 200 grams 10 VA 200-1700nm 5 min 15 UV – 45 VIS 2800K +1-813-855-8687 • Price $ 2800 $ 595 $ 295 Output to bulb Output fluctuation Deuterium bulb lifetime Tungsten bulb lifetime Spectral attenuation Connector Internal 0.004 %p-p 800 hours 1000 hours 450nm dip SMA 905 www.StellarNet-Inc.com
