(1) See Section 7.5 for more information.

(2) See the package mechanical characteristics for details regarding the size and location of the window aperture.

(3) The active area of the DLP471TP 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.

(4) Angle of incidence (AOI) is the angle between an incident ray and the normal to a reflecting or refracting surface.
