L Dwarfs span the transition between stars and brown dwarfs, while T Dwarfs are all brown dwarfs. The MIPS program on these objects has two goals. The first is to obtain measurements of the 24 micron brightness of ~30-40 `L' and ~8 `T' Dwarfs, and of a comparable number of M stars with spectral types later than M5. To the extent possible, the targets will be selected to overlap with the IRAC and IRS programs. The photometry will provide the longest wavelength point in the spectra of these objects, in a region of the spectrum which is relatively uncomplicated compared to the visible through 15mum region, having only very broad absorptions by molecular hydrogen. As such, our photometry will serve as an anchor for determinations of the relationship between radius and luminosity. The photometry of late-type M stars will also be the first ever at such long wavelengths, and the data will also complement IRAC and IRS measurements which will be obtained for the same objects. The second goal emphasizes observations at 24mm (overlap with IRAC and IRS is not required, but is generally desirable). Since the 24mm luminosity of an L dwarf is only weakly dependent on its temperature, mass, or atmospheric parameters, flux measurements can be converted to distances in a straightforward way.
