6.5.3 Illumination Overfill

The active area of the device is surrounded by an aperture on the inside DMD window surface that masks

structures of the DMD chip assembly from normal view and is sized to anticipate several optical operating

conditions. Overfill light illuminating the window aperture can create artifacts from the edge of the window

aperture opening and other surface anomalies that may be visible on the screen. The illumination optical system

should be designed to limit light flux incident anywhere on the window aperture from exceeding approximately

10% of the average flux level in the active area. Depending on the particular system optical architecture, the

overfill light on the window aperture may have to be further reduced below the suggested maximum 10% level in

order to be acceptable.
