Use the calculation program on WolfVision's internet homepage to calculate the exact position and
image sizes :
The distance is measured from
the bottom of the Ceiling
Visualizer to the working
surface. These figures may vary
a little in reality, because the
position of the focus influences
the size. Masking of the monitor
or projector should also be taken
into consideration (i.e. some
units cut off the edges of the
picture). Theoretically larger
distances than 4000mm (approx.
160") are possible, but the pick-
up size would be too large and
the light output too low.
The size of the smallest and largest image that the unit can pick up is not fixed. It depends on the
distance between the working surface and the bottom of the Visualizer. The tables below show the
relationship between mounting height and pick-up sizes:
INSTALLATION
In extremely high rooms the smallest image the unit can pick-up may not be small enough. In such
cases a standard ceiling mount or projector-lift can be used to suspend the Ceiling Visualizer further
from the ceiling.
