* Includes the Model 141WLS and power pack.
The Model 141WLS provides a reference white light source with warm and cool light outputs to be used with the Model 141 Visual Spectrometer. The adjustable-temperature broad-band white light source is for observation and photography of absorption spectra of colored solutions. The cooler temperature (black push-button) helps students visualize the effect of change in the Boltzman energy distribution—the loss of high-energy blue light with decrease in source temperature. The light source is powered by a UL-rated 12VAC wall-mount power block. The Model 141WLS can be purchased separately or in a Model 141V package.
