8.3 Configuring the lens, dynamic focus
About focus drift and dynamic focus
Due to the design of TLD + lenses and ultra-short throw lenses (UST lenses), these type of lenses tends to
heat up over time when used in projectors. This has the side-effect of a slight shift in focus between the lens in
its cold state and the lens in its heated state, which is referred to as "focus drift".
While there are external solutions available that perform a "focus drift compensation", a dynamic focus feature
has been implemented from Pulse software version 2.0 onward that handles this focus drift. While enabled,
the projector will perform the necessary calculations in order to handle this drift in focus.
The amount of focus drift can differ between lenses. For that reason it is important to calibrate the
focus drift when a new lens is mounted in the projector.
Use the calibration wizard in the Projector Toolset to calibrate focus drift. For more info on the focus
drift calibration, consult the Projector Toolset user guide.
