Section 2: Installation and Setup

2.6 MAXIMIZING LIGHT OUTPUT

Upon powering with a newly-installed/replaced lamp, adjust

lamp position to help ensure optimized operation, as well as peak

brightness at the screen. Once you have done this LampLOC™

adjustment, the lamp will be well-centered and distanced

correctly from the remainder of the illumination system.

At the TPC, automatically optimize lamp position by pressing

the DO AUTO button in the Advanced:Lamp menu. Watch the

gauge on this menu. After 2-3 minutes, the best lamp position

will be established (using an internal light sensor) and the DO

AUTO button will no longer be disabled. At this point, light

output is optimized.

NOTE: The lamp must be ON and the douser (shutter) open

during LampLOC™ adjustment; however, the projector does not need to be displaying an image.

2.6.1 DETERMINING SCREEN BRIGHTNESS (FL)

In order for the TPC to display screen brightness in footlamberts (fL), you must measure screen

brightness at both extremes of lamp power (minimum and maximum) for a given lamp type, and

record these two readings in the TPC Admin:Lamp menu. These measurements establish a range

(stored in memory) from which the TPC can interpolate all other lamp power settings, converting them

to approximate footlamberts for display in the menus. Repeat the calibration when switching to a

different lamp type/size.

2.7 BASIC IMAGE ALIGNMENT

NOTE: Assumes projector is fully assembled and powered up in its final location.

This procedure ensures the image reflected from the DMDs is parallel to and well-centered with both

the lens and screen. This initial optical alignment is the foundation for optimizing images on the screen

and must be completed before final boresight adjustments. Before beginning the CP2000 must be

properly positioned relative to the screen.

2.7.1 BASIC OPTICAL ALIGNMENT PROCEDURE

1. Display a good test pattern appropriate for analyzing image focus and geometry, such as a single

crosshair centered across the image.

2. Coarse focus: Do a quick preliminary focus and (if available) zoom adjustment with the primary

lens only. Do not worry about consistency across the image at this point, just center focus.

3. Center the image in the lens: Holding a piece of paper at the lens surface, adjust offsets until the

image is centered within the lens perimeter. A full white field works best.

4. Re-check side-to-side leveling: Using a good test pattern, double-check projector leveling (2.4

Adjust Tilt and Leveling) so the top edge of the image is parallel to the top edge of the screen.
