Wavelength transmittance for DLP DMD window
The digital micromirror device (DMD) efficiency observed in a specific application depends on applicationspecific design variables such as illumination wavelength, illumination angle, projection aperture size, overfill of the DMD micromirror array, and so on. Overall optical efficiency of each DMD can generally be estimated as a product of window transmission (2 passes), diffraction efficiency, micromirror surface reflectivity, and array fill factor. The first three factors depend on wavelength of the illumination source. This application report provides information specifically on transmittance of DMD windows in different regions of the electromagnetic spectrum.
