(2) See the package mechanical characteristics for details
regarding the size and location of the window aperture.
(3) The active area of the DLP3310 device is
surrounded by an aperture on the inside of the DMD window surface that masks
structures of the DMD device assembly from normal view. The aperture is sized to
anticipate several optical conditions. Overfill light illuminating the area
outside the active array can scatter and create adverse effects to the
performance of an end application using the DMD. The illumination optical system
should be designed to limit light flux incident outside the active array to less
than 10% of the average flux level in the active area. Depending on the
particular system's optical architecture and assembly tolerances, the amount of
overfill light on the outside of the active array may cause system performance
degradation.
