Yellow Notch Filter Adjustment

UV HAZARD! When servicing the projector with the top lid removed anyone within the
immediate vicinity must wear safety glasses with side shields.
The angle at which light passes through the yellow notch filter affects the final color of light arriving at the
light engine, which in turn affects color accuracy in projected images. By carefully adjusting the yellow notch
filter angle while using a spectrophotometer (such as the SpectraScan PR650) to measure the CIE 1931 color
coordinates of a full green image, the precise green color coordinates, which are crucial for producing accurate
colors for the final display, can be obtained. Adjust the yellow notch filter whenever it is moved or replaced, or
when a new Illumination Optics System (IOS) is installed.
1. Set up a spectrophotometer, such as the SpectraScan PR650, at the image in the theatre.
2. With the top lid removed, display a full green field.
3. Measure the green coordinates using a spectrophometer.
4. Locate the adjustment screw on the center of the yellow notch filter frame and adjust as necessary to obtain
the following coordinates:
• x = 0.265 (±0.02)
• y = 0.690 (±0.02)
