Reference 1, 2 and 3 are adjustment points. Reference 4 is a locking point and NOT used during
Scheimpflug adjustment.
When to apply Scheimpflug?
Only apply a Scheimpflug correction in case the overall focus of the projected image is not equally sharp (can
be caused if the projector is
NOT in parallel
with the screen or a previous misaligned Scheimpflug) . Take into
account that the consequence of applying Scheimpflug correction upon a screen not in parallel with the
projector is that the projected image differs from the rectangle shaped image. In other words
“
distortion
”
of
the projected image occurs.
Masking
will be required to solve the distortion.
The disadvantage of Masking is loss of content. Therefore it is strongly
recommended
to place the projector
in parallel
with the projection screen and use the
SHIFT
functionality of the Lens Holder to match the
projected image with the projection screen. In case the SHIFT range is not sufficient then the projector can be
tilted and Scheimpflug can be applied.
11.2 Scheimpflug adjustment
Required tools
•
3mm Allen wrench.
•
13mm nut driver.
•
10mm nut driver.
Preparation steps:
1.
Ensure that the throw ratio of the installed lens matches the requirements of the application (projection
distance and screen size).
2.
Ensure that the correct lens parameters are activated. (See user guide of the
