POSITIONING THE SCREEN AND PROJECTOR
Positioning The Screen And Projector
Notes
Calculation
The lens should only be used on
flat surfaces and must be aligned
parallel to the screen.
Positioning is determined by:
•
•
throw - the distance between the projector and the screen, and
offset - the distance between the ground and the bottom edge of the screen.
The throw formula on this page
uses easy to measure reference
points: the screen surface and the
front of the projector. In reality the
throw is measured from a point
inside the lens which is 196 mm
away from the front of the projector.
These figures are calculated using the screen width in millimeters, using the following formulae:
throw = screen width (in millimeters) x 0.35134 - 196 mm
offset = screen width (in millimeters) x 0.2586 + 140 mm
Throw
Likewise, the offset formula uses
a correction of 140 mm because
in reality the offset begins 140 mm
above the ground.
Offset
The screen width must be in mm.
For screen widths below 2223
mm, the rear of the projector is in
line with the screen wall. Space
must be left behind the projector
for ventilation: for E-Vision Laser
7500 and E-Vision Laser 8500 the
minimum distance should be 500
mm. For further information, see the
projector user manual.
Lens tolerance can be up to 5%.
Offset is also dependent on lens
shift
