Near-infrared (NIR) spectra that have an angular resolution of ~ 0.15 arcsecare used to examine the stellar content of the central regions of the nearbyelliptical galaxy Maffei 1. The spectra were recorded at the Subaru Telescope,with wavefront distortions corrected by the RAVEN Multi-Object Adaptive Opticsscience demonstrator. The Ballick-Ramsey C_2 absorption bandhead near 1.76microns is detected, and models in which 10 - 20% of the light near 1.8 micronsoriginates from stars of spectral type C5 reproduce this feature. Archival NIRand mid-infrared images are also used to probe the structural and photometricproperties of the galaxy. Comparisons with models suggest that an intermediateage population dominates the spectral energy distribution between 1 and 5microns near the galaxy center. This is consistent not only with the presenceof C stars, but also with the large HBeta index that has been measuredpreviously for Maffei 1. The J-K color is more-or-less constant within 15arcsec of the galaxy center, suggesting that the brightest red stars arewell-mixed in this area.
