Tungsten halogen sources are the standard VIS-NIR light sources for absorbance, reflectance of solid objects, and color measurement. The workhorse of the absorption and reflection spectroscopy, the visible region has the most experiments for everything from enzyme kinetics measurements to colorimetric protein analysis. For these routine measurements, lamp power and stability are critical specifications.
