12 Positioning the projector
The projector should be installed at right angles (horizontally and vertically) to the screen at a distance PD.
Note the distance (A) between lens centre and table surface is slightly variable. This distance (A) is nominal
223 mm in case all feet are turned in completely and the vertical lens shift is set to zero (0).
On axis / off axis projection
The position of the projector with reference to the screen may also be different depending on the installation.
Basically the projector can be positioned in On-Axis or Off-Axis configuration. On-Axis configuration means
that the projector is positioned so as to have the centre of the lens coinciding with the centre of the screen.
Off-Axis projection is obtained by shifting the lens up, down, left or right. Several parameters can be calculated
determining the position in any installation.
Formula to calculate the distance CD for On-Axis projection:
CD = SH/2 + B - A
Maximum shift range
All lenses have a shift range of 50% up, 70% down, 30% left, and 30% right. This range is valid for all throw
ratios. Within these shift ranges the projector and lens will perform excellently.
These are the mechanical limits of the B-Lens holder. It is not possible to configure the projector
outside of these shift ranges.
