4.7 Installation of a lens on a B-Lens holder
Take into account that when using an XDM projector with a B-lens holder, you will also need the
optical adapter for the B-lens holder, which is provided with the projector. If the optical adapter is not
used, it will not be possible to achieve a perfect focus on your projected image.
Take into account the limited range of available lenses for an XDM projector with a B-lens holder.
For the full list of available lenses, refer to
“ Available lenses ” , page 39 .
Why use the optical adapter?
In order to reuse as many older lenses as possible on this new generation of projectors, a secondary lens
holder has been created for the XDM projector. This B-Lens holder has been designed to reuse lenses from
the legacy B-Series cinema projectors. But in order to do obtain a correctly focused image, you will also
require an optical adapter. This adapter is included with all projectors with B-Lens holder.
While the adapter does not lock onto the lens barrel, it is held in place by tightening the screw of the clamping
ring.
CAUTION: Make sure you have removed the lens cap from the lens before mounting the optical
adapter.
Required tools
Torque wrench with hex bits
Required parts
• Optical adapter for B-Lens holder
• Ring 1 or 2 for the optical adapter (depending on the used lens)
• 3 M3 Screw inserts (in case ring 1 is used)
• 3 M3x5 hex screw (in case ring 1 is used)
• 3 M4 screw inserts (in case ring 2 is used)
• 3 M4x8 hex screws (in case ring 2 is used)
Preparing a B-series lens for installation on a B-lens holder
1. Check the list of the position of the optical adapter for B-Series lenses to see which adapter ring to use for
your lens. For more info, see
“ Position of the optical adapter for the B-lens holder ” , page 94 .
2. Place the appropriate adapter ring (ring 1 or ring 2) on the back of the lens.
Tip: Pay attention to the orientation of the ring while mounting it . Make sure the bottom of the
printed number and the pins point outwards (reference 1, Image 4 – 18 ).
Also pay attention to the lips of the adapter ring (reference 2, Image 4 – 18 ). They need to snap in
place and will prevent the ring from falling off. Be careful not to break these while mounting the
ring.
