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