A compact light source
LS-DW is a compact light source that combines the continuous spectrum of deuterium and tungsten lamps into a single optical fiber SMA connector. The combined spectrum produces a stable output and delivers the ideal light intensity for most absorbance and transmittance measurements ranging from 185 to 1100 nm.
Granted flexibility
The local shutter with integrated controller included in the DW light source, in addition to allowing simple operation for dark measurements, reduces sample exposure to UV light without the need to turn off the light source, resulting in a more stable and extended lifetime of the lamps. The lamp controller makes it easy to select between individual or combined deuterium and tungsten-halogen lamp operation.
Key features
Select only the lamp you need
The DW light source has an integrated lamp selector that allows you to choose between a single and combined deuterium and tungsten-halogen lamp operation, according to your spectral region of interest.
Shutter control for maximum performance
The built-in shutter controller included on the DW light source enables a simple operation for dark measurements or reducing the exposure of samples to UV light without the need for shutting off the light source, resulting in a more stable and extended lamps lifetime.
Control your light source remotely
The DW light source can be remotely controlled by using our SPEC Hub. Creating event tables for turning on/off the light source, selecting individual or combined lamp illumination, and enabling/disabling the shutter has never been so easy!
