The Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) is an upcoming all-sky near-infrared spectroscopic survey satellite designed to address all three primary science goals of NASA’s Astrophysics Division. SPHEREx employs a series of Linear Variable Filters (LVFs) to create 102 spectral channels across the wavelength range of 0.75 to 5 μm, with spectral resolutions R between 35 and 120. This paper presents the spectral calibration setup used for SPHEREx and discusses the various challenges encountered during the measurement process. Ultimately, we demonstrate the spectral responses for all 25 million pixels in SPHEREx.
