3. CENTER THE IMAGE IN

THE LENS: Holding a piece

of paper at the lens surface,

adjust offsets as necessary

until the image is centered

within the lens perimeter. A

full white field works best for

this.

4. RE-CHECK SIDE-TO-SIDE LEVELING: With a good test pattern on screen,

double-check projector leveling (see 2.3, Projector Position and Mounting)

so that the top edge of the image is parallel to the top edge of the screen. See

Figure 2.32.

NOTES: 1) Projector must be

fully assembled and powered up in

its final location. Install the

anamorphic lens, if it will be used

at the site. 2) You will need a

3/16” allen wrench.

To ensure proper offset for your

site and consistently good focus in

all areas of the screen, a primary

lens must be installed and its lens

mount precisely adjusted in

relation to internal optics as

described below. If desired, an

anamorphic lens can then be added

to widen images for “scope”

cinema displays. Once adjusted, boresight should remain stable until the lens is

replaced.

Refer to lens mount components illustrated in Figure 2.33. for these adjustments.

Project an image with the primary lens only. The optional auxiliary lens, if

present, can be mounted but swung aside.

Adjust horizontal and vertical

offsets as necessary (Figure 2.34)

so that the image is square on

screen. Always adjust offset before

boresight. NOTE: For best

performance and minimum

keystoning, particularly in long

throw theatres, make sure to

minimize offsets by “aiming” the

projector lens at the center of the

image. Refer back to Vertical &

Horizontal Position. In short throw theatres with stadium seating, use a

combination of offset and aiming.
