Deuterium Tungsten / LS-DW
LS-DW is a complete UV/VIS/NIR light source with a deuterium and a tungsten-halogen lamp in shine-through configuration, shutter and SMA 905 connector. Due to it’s high stability and reliability is the perfect solution for absorbance and transmittance measurements.
In all supplied sources is also included a shutter that allows a simple operation for dark measurements and eliminates the need to turn off the lamps resulting in more stability and extended lifetime.
The remote control allows lamp selection and shutter operation via D-SUB connection.
The useable wavelenght range from this Light Source is from 200 to 1100 nm but can be extended to 185 nm with a Deep UV optional Deuterium lamp. Both lamps can work independently in the spectral region of interest for extended life time. The lamps are easily replaceable due to a simple connection and to a pre-aligned mounting ring.
