15.5 Scheimpflug adapters
The Scheimpflug adapters for Ranger3 make it possible to create a camera setup
where the plane of focus is parallel to the laser line. This means that a subject that is
not parallel to the image plane can be rendered sharply. Adapters with three different
tilt angles are available, see "Accessories", page 75.
Scheimpflug adapters are based on the Scheimpflug principle, which decribes a situa‐
tion where the lens plane is not parallel to the image plane of the sensor. When a line is
extended from the image plane, and another is extended from the lens plane, they
meet at a point through which the plane of focus also passes.
