Remove lens
It’s recommended to place the Lens caps of the original Lens packaging, back on both sides of the removed
Lens to protect the optics of the Lens.
It’s recommended to place the foam rubber of the original projector packaging, back into the Lens opening to
prevent intrusion of dust. Note that this foam rubber is packed in a plastic bag to prevent the dust, emitted by
the foam, from entering the projector.
7.5 Lens shift, zoom & focus
Motorized lens adjustment
The DPxK BLP series projector is equipped with a motorized lens shift functionality and a motorized zoom & focus functionality.
Maximum shift range
The lens can be shifted with respect to the internal optics of the projector (DMD) which 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 screen size. In other words, the
centre point 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 limited as well.
All lenses have a shift range of 50% up, 50% down, 30% left, and 30% right. This range is valid for all throw ratios. Within these shift
ranges the projector and lens perform excellently. Con
fi guring the projector outside these shift ranges will result in a slight decline
of image quality.
