The B-se ries p rojector is equipped with a motorized lens shift f unctionality and a m oto rized zoom & focus functionality.
Maximum shift range
The lens can be shifted with respect to the DM D wh ich result in a shifted image on the screen ( Off-Axis). A 100% s hift means that
the centre point of the projected image is shifted by half the s creen 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 DP 2K lenses ha ve a shift range of 50% u
p/down and 30% left/right. T his range is valid for all throw ratios.
