  We present the design and lab performance of a prototype lenslet-slicer
hybrid integral field spectrograph (IFS), validating the concept for use in
future instruments like SCALES/PSI-Red. By imaging extrasolar planets with IFS,
it is possible to measure their chemical compositions, temperatures and masses.
Many exoplanet-focused instruments use a lenslet IFS to make datacubes with
spatial and spectral information used to extract spectral information of imaged
exoplanets. Lenslet IFS architecture results in very short spectra and thus low
spectral resolution. Slicer IFSs can obtain higher spectral resolution but at
the cost of increased optical aberrations that propagate through the
down-stream spectrograph and degrade the spatial information we can extract. We
have designed a lenslet/slicer hybrid that combines the minimal aberrations of
the lenslet IFS with the high spectral resolution of the slicer IFS. The slicer
output f/\# matches the lenslet f/\# requiring only additional gratings.
