Type Ia supernovae have emerged as excellent cosmological tools. Near infrared photometry becomes increasingly important as observations are pushed to higher redshifts. In particular, near-IR observations can be used to estimate reddening and assess systematic effects such as grey dust. We present infrared photometry of five supernovae obtained using the NICMOS detector on HST. The observed supernovae range in redshift from 0.35 to 0.86. The low background in these images provides more precise photometry than is possible from the ground and the higher resolution allows for a more reliable estimate of host galaxy contamination. We will present data reduction techniques, cosmological implications, and summarize the difficulties of doing absolute photometry using NICMOS. This research is supported by the Department of Energy and by the NASA Space Telescope Science Institute.
