Deuterium Tungsten HPower / LS-DWHP

With 30 W Deuterium and 20 W Tungsten-Halogen lamps, the LS-DWHP is the most complete high power UV/VIS/NIR light source. Configured in shine-through design, with 12.7 focusing lens for maximum light collection, local or remote operation and SMA 905 connector. Both lamps can work independently in the spectral region of interest for extended life time, and are easily replaceable.

In all supplied sources is also included a shutter which allows a simple operation for dark measurements and eliminates the need to turn off the lamps.

The remote operation allows lamp selection and shutter control via D-SUB connection with a TTL compatible signal.

This light source includes a slot filter holder which makes the  change between Sarspec’s slide filters quite easy. This feature is also very convenient for fluorescence measurements. By adding neutral density filters it’s also possible to perform Absorbance and Transmittance measurements.

The spectral irradiance for both Deuterium (left) and Tungsten (right) lamps are in the images below.
