Spectral response of pressure-modulator-radiometer cell measured with help of lead-salt tunable diode laser. Laser chosen because of narrow bandwidths {2 x 10 to negative 4th power (cm) to negative 1st power} and relatively high powers (up to 1 mW continuous) of such lasers and because available for wavelengths from 3 to 30 micrometers. Direct measurement of spectral response enables formulation of more-precise atmospheric-transmission functions, enabling extraction of better information from readings taken with instrument.
