Aligning the integrator module
The integrator module is located early in the light path, between the UV filter and cold mirror.
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. Therefore,
when 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.
Warning! Failure to comply with the following could result in death or serious injury.
•
UV EXPOSURE! Protective UV safety glasses with side shields and Christie approved protective
safety clothing must be worn when performing optical adjustments or servicing the product.
Caution! Failure to comply with the following could result in minor or moderate injury.
1. Display a full white field.
2. Loosen the integrator assembly so that it can be manually moved.
3. Adjust the focus.
Corners should be equal in focus, although they may 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 the perimeter shadows with a full black field.
4. Center the white field.
Confirm that all shadowy edges cast by the integrator are projected off the screen, with the
white field fully visible and centered between shadows. 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.
