Abstract Multispectral aerosol absorption and scattering measurements with photoacoustic spectrometers and nephelometers are typically performed by multiple instruments or by combining the output from multiple light sources. Currently, our groups are developing a photoacoustic aerosol light absorption and albedo spectrometer (PALAAS) using a supercontinuum light source with continuous wavelength-coverage from 400nm to 2500nm. This system critically depends on the beam characteristics of its supercontinuum light source. Here, we discuss the characterization and evaluation of beam properties of supercontinuum light sources utilizing mirror- and lens-based collimators.
