This talk will cover recent technological advances enabling the construction of a microscope capable of measuring broadband transient absorption images, ultrafast 2D white-light spectra with sub-micron spatial resolution, and correlating those images to an atomic force topological images.  The microscope operates at 100 kHz, with delay trains created by a shot-to-shot pulse shaper and a fast readout detector.  Data will be show on a singlet fission material in which the slip-stack geometries have been identified and their population imaged across microcrystals. Spatially resolved transient absorption data reveals that these slip-stacked geometries impact singlet fission kinetics.  The data reveals interesting new physics in singlet fission and illustrates the capabilities of this new microscope.  <br/>
