5.4 UST lenses
5.4.1 About UST lenses
About the TLD+ 90° Ultra Short Throw (UST) lenses
The UST lenses are exclusively designed to be used on Barco projectors. The lens output is turned 90°. This
allows for an optimal use of the vertical shift range when projecting to the left seen from the rear side of the
projector.
This lens is designed for ultra short throw video performance.
The lens shift can be +/-150%, depending on projector type. Please use the Barco Lens calculator to calculate
actual values for the projectors used in your setup.
Different motor block orientations
The previous generation rental projectors (HDX and HDF) had a different lens holder when compared to
Barco’s current generation rental projectors (UDX, UDM and XDM with C-lens holder). One of the big
differences between these two types of lens holder is that the socket for the electrical connection has a
different orientation.
For this reason the UST lenses that can be used on both generations rental projectors are designed with a
motor block that can easily be rotated around the lens body. This allows that the lens output direction remains
the same while the electrical plug on the motor block can be turned to matches the electrical plug on the lens
holder front plate. See the following example illustrations.

For UDX, UDM and XDM projectors, the motor block must always be located above the lens body (ref. 1)
when facing the projector from the front side in table mount. For HDX/HDF series the motor block must always
be located at the right side (ref. 2) of the lens body when facing the projector from the front side in table mount.

The lens body can be rotated per 90° relative to the motor block. However, the most common configuration is
probably with the lens output oriented to the left seen from the rear side of the projector in table mount. Other
