Abstract

Two spectrometers, utilizing interference filter wedges, have been constructed for measurements under field conditions. One, operating from 1.6 μ. to 5.4 μ, has been flown unpressurized in an airplane to 12.2 km; the other, operating from 7.4 μ to 14.6 μ has been flown in a balloon to 33.3 km. Both instruments performed well, proving the interference filter wedge as a valuable tool for spectral measurements, especially in hostile environments.
