Deuterium/Tungsten light source

 StellarNet has announced a new, miniature Deuterium/Tungsten light source covering the 200-1700nm range in a single unit. Its high output power enables use for reflectance measurements, where lower power light sources (like SL5-DH) are too weak.

A shutter button on the front panel blocks light output of both lamps, necessary for dark reference spectrums without turning off the source. Additional filters and optics allow the D-alpha line (654nm) to be eliminated in the deuterium source.

The small size (72 x 40 x 90mm) makes it a perfect match for StellarNet miniature UV-VIS spectrometers and also reduces complexity allowing it to be connected to a battery pack for field applications.
