Abstract
In one embodiment, a radiation based analysis system comprises a first radiation source to generate first radiation having a wavelength outside the visible spectrum, a second radiation source to generate second radiation having a wavelength within the visible spectrum, and a waveguide coupler to couple a portion of the first radiation and a portion of the second radiation into a combined radiation beam such that the first radiation and the second radiation follow a path that is substantially coaxial.
