It’s recommended to place the plastic cover of the original projector packaging, back into the Lens opening
to prevent intrusion of dust.

Lens shift, zoom & focus
Motorized lens adjustment
The Athena 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 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.

It’s mechanical possible to shift outside the recommended
fi
eld of view (±90% UP/DOWN 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.
