Positioning 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 35 cm 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 con
fi
guration. On-Axis con
fi
guration 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
Shift range
The lens can be shifted with respect to the DMD (P) 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 and optical limitations it’s recommended to keep
the shift values within the
fi
eld of view (F) as illustrated below. 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.
