lamp replacement and lamp safety may handle the lamp. High-pressure lamp may explode if
improperly handled. Always wear Christie approved protective safety clothing (P/N: 598900-
095) whenever the internal lamp door is open or while handling the lamp.
The integrator module is located early in the light path, between the cold mirror and fold mirror 1. Its chief
component, the internal solid silica pipe, efficiently converts the initial round light beam supplied from the
lamp into a uniform rectangle that passes through the remainder of the optical system and eventually
illuminates the three DMDs at the opposite end of the light path. Whenever the integrator module is moved or
replaced, its end-to-end position, as well as its rotation, must be correct for proper focus and full illumination
of the three DMDs.
1. Display a full white field.
2. Loosen the integrator assembly so that it can be freely moved by hand.
3. Focusing: Corners should be equal in focus, although they may all appear slightly blurry. As necessary,
move the integrator forward or backward along its axis for an equal level of focus in all corners. For best
results, double-check perimeter shadows with a full black field. (Figure 3-2)
4. Centering: Confirm all shadowy edges cast by the integrator are projected OFF the screen, with the white
field fully visible and centered between shadows (Figure 3-3). If necessary, use the fold mirror adjustment
screws to precisely direct the white field between all edge shadows. Centering signifies that the rectangle
of light passed from the integrator completely illuminates the DMDs.
