(1) Measured relative to the plane formed by the overall micromirror array
(2) Represents the variation that can occur between any two individual micromirrors, located on the same device or located on different devices.
(3) For some applications, it is critical to account for the micromirror tilt angle variation in the overall system optical design. With some system optical designs, the micromirror tilt angle variation within a device may result in perceivable nonuniformities in the light field reflected from the micromirror array. With some system optical designs, the micromirror tilt angle variation between devices may result in colorimetry variations, system efficiency variations, system contrast variations, and optical power variations.
(4) When the micromirror array is landed (not parked), the tilt direction of each individual micromirror is dictated by the binary contents of the CMOS memory cell associated with each individual micromirror. A binary value of 1 results in a micromirror landing in the ON State direction. A binary value of 0 results in a micromirror landing in the OFF State direction. See Figure 6-10.
(5) The time required for a micromirror to nominally transition from one landed state to the opposite landed state.
(6) The minimum time between successive transitions of a micromirror.
(7) An out-of-specification micromirror is defined as a micromirror that is unable to transition between the two landed states within the specified micromirror switching time.
(8) Efficiency numbers assume 35-degree illumination angle, F/2.4 illumination and collection cones, uniform source spectrum, and uniform pupil illumination.
  • Window Transmission 94% (double Pass, Through Two Window Surfaces)
  • Micromirror Reflectivity 88%
  • Array Diffraction Efficiency 84% (@f/2.4)
  • Array Fill Factor 93%
Efficiency numbers assume 100% electronic mirror duty cycle and do not include optical overfill loss. Note that this number is specified under conditions described above and deviations from the specified conditions result in decreased efficiency.
