One of the most basic tasks in spectroscopy is to characterize the spectrum of a light source: how much light is emitted at each different wavelength. The most straightforward way to measure a spectrum is to pass the light through a monochromator, an instrument that blocks all of the light except the light at a certain wavelength (the un-blocked wavelength is set by a knob on the monoc… WebbThe k-weighting is controlled by the bank of check buttons labeled 0, 1, 2, 3, and kw, and located just beneath the purple plot buttons.
