3.5 Tilt Angle

The Tilt Angle input follows the table below for a majority of applications. The user is given the flexibility to test the efficiency in the mirror on-state and the various maximum and minimum tilts. Table 3-1 shows typical DMD pixel models with the associated pixel pitch, tilt angles, and illumination angle.

Note: Please visit the specific DMD data sheet for more information regarding tilt angle min and max ranges.
