Abstract

A constant output monochromator has been developed that produces a power of 100 ± 2 μW over a wavelength range from 375 nm to 1400 nm with a spectral bandpass of 20 nm. The output is regulated by controlling the source intensity and the monochromator transmission. A thermopile is incorporated into the instrument for calibrating the output of the open loop system.
