The Multi-Spectral Imaging (MSI) diagnostic is a new instrument that captures simultaneous spectrally filtered images of atomic line radiation from a common sight view while maintaining a large etendue and high spatial resolution.  In short, the diagnostic can be thought of as a 2D spectrometer.  By observing atomic emission in 2D, we may infer the temperate, density, and transport along the divertor.   The MSI was installed at CMOD in Fall 2016 and was installed at TCV in Summer 2017.  This talk will review the relevance of atomic physics to MFE and the work currently being done with the MSI at TCV.
