  We present phase-resolved low resolution infrared spectra of AM Her and ST
LMi, two low-field polars that we observed with SPEX on the IRTF. Optical/NIR
lightcurves are also published to help constrain the viewing geometry and
brightness of the objects at the time they were observed. Currently, only
limited IR spectra have been published for these objects, and none with the
phase-coverage presented here. In both cases, the resulting spectra are
dominated by emission from the secondary star in the NIR. However, the emission
regions are also self-eclipsed, allowing us to isolate the cyclotron emission
through subtraction of the dim-phase spectrum. We use a ``Constant Lambda''
prescription to model the changing cyclotron features seen in the resulting
data. For AM Her, we find a best fit model of: B = 13.6 MG, kT = 4.0 keV, and
logLambda = 5.0. The cyclotron derived accretion geometry is consistent with an
orbital inclination of 50 degrees and a magnetic co-latitude of 85 degrees. For
ST LMi, B = 12.1 MG, kT = 3.3 keV, and logLambda = 5.7 with an orbital
inclination of 55 degrees and a magnetic co-latitude of 128 degrees.
