The lens calculator will be displayed.
The lens calculator allows you to have an overview of which lenses are suitable for your specific projector
setup. Just make your selection of parameters and all possible configurations are displayed.

Take into account that when the projector is tilted the Screen Width you have to fill in should be
larger than the physical screen width due to the keystone distortion of the projected image. How
much larger depends on the amount of tilt.
Due to production tolerances the real distances can differ by 2% from the calculated values.
For critical situations (fixed installs that use the lens at one of its extreme zoom positions) this
should be taken into account.
6.3 Lens installation
How to install a lens into the Lens Holder?
1. Remove the foam rubber in the opening of the Lens Holder if not removed yet.
2. Take the lens assembly out of its packing material and remove the lens caps on both sides.
Caution: Do not touch the glass of the lens!
3. Ensure that the Lens Holder stands in the On-Axis position (horizontal and vertical mid position).
4. Place the Lens Holder in the “ locked ” position by moving the lens lock handle (1) downwards, away from the
lens power supply socket (2).
5. Gently insert the lens in such a way that the lens connector matches the socket. To prevent collision of the
lens with the critical electronics inside the projector, ensure you centre the lens and keep it on-axis while
approaching.
Caution: Do not accidentally bump with the lens against the electronic boards inside the Lens Holder.
Warning: Do not release the Lens yet, as the Lens may fall out of the Lens Holder.
