5.5 Lens shift, zoo m & focus
Motorized lens adjustment
The D P2K SLP- series is equipped with a motorized lens shift and zoom & focus functionality.
Maximum shift range
The lens can be shifted with respect to the internal optics of t he p rojector (DMD) whic h results in a shifted image on the screen
(Off-Axis). A 100% shift means that the centre point of the projected image is shifted by half the sc reen size. In other words, the
centre p oint of the projected image falls together with the outline of the image in an On-Axis projection. Due to mechanical and
optical limitations the shift range is lim ited as well.
All lenses have a shift range of 50% u p, 50% down, 30% left, and 30% right. This range is valid for all throw ratios. Within these shift
ranges the projector a nd lens perform excellently. Configur ing the projector outside these s hift ranges will result in a slight decline
of image quality.

It’s mec hanical possible to shift outside the reco mm ended field of view (±90% UP/DOW N and ±50%
LEFT/RIGHT), but this will result in a decline of image quality depending on the used lens and the zoom
position of the used lens. Furthermore, shifting too much in both directions will result in a blurred image
corner.
