5. Lenses & lens holder
5.6 Lens shift, zoom & focus
Motorized lens adjustment
The DP2K-32B 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 DMD which result 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 an optical limitations the shift range is limited as
well.
All DP2K lenses have a shift range of 50% up/down and 30% left/right. This range is valid for all throw ratios.
How to shift the lens of the DP2K-32B?
