Abstract: We are currently developing an instrument that mates TNTCAM2 (Klebe et al. 1998), an imaging polarimeter, with a Fourier transform spectrometer (FTS), that operates from 2 to 15 μm. The FTS component enhances TNTCAM2, giving the instrument a maximum resolution of 2000 at 10 μm, and 104 at 2 μm, while preserving the imaging capabilities. This enables both moderately high resolution imaging spectro-polarimetry of point sources, and the mapping of polarization vectors over an extended nebulous region as well. Potential scientific targets and discoveries will be discussed as well as the control of the FTS moving mirror as related to waveplate rotation and the observational technique of chopping & nodding necessary for ground based observations in the IR.
