LS-1 Series Tungsten Halogen Light Sources
LS-1 Series Tungsten Halogen Light Sources
9
Spectral Output: LS-1 and R-LS-1
The graph on the left represents normalized blackbody curves for tungsten halogen light sources with 2800K and
3100K color temperatures. The observed spectral output of the LS-1 will vary due to bulb type, spectrometer
configuration, sampling optics in use, and inherent fluctuations in LS-1 output.
The graph on the right represents the Scope mode signal from the LS-1 with and without the BG-34 filter.
