Image 11-12) against the Lens Holder front plate without disturbing the projected image.

Note:
Ensure that the edges of the projected test pattern remain in place on the screen. Any
movement of the image will affect the Scheimpflug adjustment.

until the Scheimpflug nut and set screw are completely tightened.

11.4 Back Focal Length adjustment
When to adjust the Back Focal Length?
If a lens is used with a throw ratio suited for the application, (lens selection depends on projection distance
and screen size) typically one would NEVER need to adjust the Back Focal Length of the projector.
A Back Focal Length adjustment is only required in case the Focus range of the installed lens does not
capture the projection screen either for FLAT and/or for SCOPE. In other words, when it is impossible to focus
the image on the screen for FLAT and/or for SCOPE. Note that the lenses for the Thor series series projector
are varifocal. So, switching between FLAT and SCOPE (zoom action) requires a readjustment of the focus.
What is Back Focal Length adjustment?
Back Focal Length adjustment means moving the lens plane (Lp), thus the Lens Holder front plate, closer to or
further from the DMD plane. The closer the lens plane to the DMD plane the further the focus range (Fr) of the
lens will be.
