2MASS bandpasses. The curve represents calculated total transmission as a function of wavelength including the atmosphere (modeled with precipitable ﹩\mathrm{water}\,=5﹩ mm), telescope optics, camera optics, and array quantum efficiency. This composite transmission is derived from witness measurements of mirror, dichroic, lens coating efficiency, and quantum efficiency measurements of similar arrays.
