an ILS auto calibration.

controls only.
The goal is to obtain good focus at the center and on all sides of the screen, including the
square patterns across the screen.

Adjusting the integrator rod and fold mirror

Understand how to adjust the integrator rod and fold mirror to control the illumination spot on the
DMD.
Extreme misalignment of projection optics can cause permanent damage to critical optical
components. Only Christie qualified technicians can perform internal optical adjustments.
The integrator rod and fold mirror adjustments are set by Christie. Make adjustments only if screen
shadows are visible.
When adjusting the fold mirror, set the light source to minimum power.
1. In the right toolbar, select Test Patterns.
2. Set the Red/Green/Blue power to less than 40%.
High power and misalignment can damage the DMDs.
3. Select the RGB-4K-Integrator Rod test pattern and display it full screen.
