Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
•
Distances calculated with the above equations will include a slight error.
minimum
L (m) = (diagonal screen size in inches) × 0.025700 - 0.055800
maximum
L (m) = (diagonal screen size in inches) × 0.035000 - 0.054000
minimum
L (m) = (diagonal screen size in inches) × 0.033900 - 0.055300
maximum
L (m) = (diagonal screen size in inches) × 0.057600 - 0.048000
minimum
L (m) = (diagonal screen size in inches) × 0.057640 - 0.114200
maximum
L (m) = (diagonal screen size in inches) × 0.094060 - 0.112900
minimum
L (m) = (diagonal screen size in inches) × 0.094210 - 0.213200
maximum
L (m) = (diagonal screen size in inches) × 0.149700 - 0.210900
(fixed focus)
L (m) = (diagonal screen size in inches) × 0.016500 - 0.058500

Shift range
Optical axis shift function allows to shift
the position of a projected image as
shown on the right.
Installable angle
Install the projector at an angle within the range shown below.
• Vertical direction
The projector may be installed at a vertical
angle of 360°.
• Horizontal direction
The projector may be installed at a horizontal
angle of ±10°.
•
The ET-ELW21 is a fixed short-focus lens.
Therefore, the lens shift function provided in the
main unit cannot be used.
