With a current catalog of over 150 known TeV sources, it becomes increasingly important to be able to measure accurate spectra of these sources at and above TeV energies. Given applications ranging from: better constraining the extragalactic background light, to locating potential cosmic ray sources, to exploring variability across a broad range of energies for better understanding of active galactic nuclei, obtaining precise spectra out to multi-TeV energies is critical. My talk will focus on one of the current problems with reconstructing gamma rays at these energies with the VERITAS array caused by detector saturation effects, and a potential solution by bypassing the issue, followed by an exploration of one of the scientific applications, constraining the extragalactic background light.
