  • Page 80 EzPro735 EzPro735 Note 1 : Tilt Angle Tolerances Limits on variability of mirror tilt half angle are critical in the design of the accompanying optical system. Variations in tilt angle within a device may result in apparent non- uniformities, such as line pairing and image mottling, across the projected image. Variations in the average tilt angle between devices may result in colorimetry and system contrast variations.
  • Page 81 EzPro735 EzPro735 Note 6 : Thermal Performance The DMD is designed to conduct residual heat energy to the back of the package where it can be removed by an appropriate heat sink. A device configured for a particular application can be manufactured with a thermal stud designated for that application.
