6.10 Micromirror Array Optical Characteristics

PARAMETER TEST CONDITIONS MIN NOM MAX UNIT
Micromirror tilt angle DMD landed state(1) 11 12 13 degree
DMD efficiency(2) 420 nm – 700 nm 66%
(1) Measured relative to the plane formed by the overall micromirror array at 25°C
(2) DMD efficiency is measured photopically under the following conditions: 24° illumination angle, F/2.4 illumination and collection apertures, uniform source spectrum (halogen), uniform pupil illumination, the optical system is telecentric at the DMD, and the efficiency numbers are measured with 100% electronic micromirror landed duty-cycle and do not include system optical efficiency or overfill loss. This number is measured under conditions described above and deviations from these specified conditions could result in a different efficiency value in a different optical system. The factors that can influence the DMD efficiency related to system application include: light source spectral distribution and diffraction efficiency at those wavelengths (especially with discrete light sources such as LEDs or lasers), and illumination and collection apertures (F/#) and diffraction efficiency. DLPA083A describes the interaction of these system factors, as well as the DMD efficiency factors that are not system dependent.
