Wavelength control is the capability to select and attenuate individual wavelengths. Specific wavelengths can then be analyzed in a spectrometer or filtered in an optical add-drop multiplexer, two of the most common applications.
With DLP technology, a dispersive optical element is used to spread an input light source into spatially separated wavelengths on the surface of the DMD chip. The number of mirrors turned on/off on each column of the DMD is used to select and attenuate the corresponding wavelength. This results in flexible and robust systems that are efficient across a large segment of the electromagnetic spectrum.
