Projection distance (L)

Max (telephoto)
Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 4:3
minimum
L (m) = (diagonal screen size in inches) x 0.0305 - 0.049
maximum
L (m) = (diagonal screen size in inches) x 0.0604 - 0.050
NOTE:
Distances calculated with the above equations will include a slight error.
*
This distance is especially recom-
mended for ceiling-mounted use and
other permanent installations.
NOTE:
Values shown are approximate. The value
for L (distance to screen) varies slightly
depending on the zoom lens characteris-
tics.
When the shortest projection distance is
used, a small amount of distortion may
occur in the image due to the zoom lens
characteristics.
The value for H (the height from the edge
of the screen to the centre of the lens) is
the value when the horizontal optical axis
shift function is not used. The value
decreases when the horizontal optical
axis shift function is used. For details,
see Shift range on page 7.
