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. Use the lens calculator to calculate actual values for the projectors used in your setup. For more info on the lens calculator tool, see “Lens selection”.

Different motor block orientations

On older Barco rental projectors (HDX and HDF) there was a different lens holder, when compared to Barco’s current rental projectors (including this projector). 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 our current projectors (including this projector), 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 the older HDX and HDF projectors 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 directions (e.g. downwards) may cause interference of the projector housing/rigging frame in the light path of the projected image.

A new Short Throw 90° zoom lens is delivered with the motor block mounted in the orientation for left projection of the current generation projectors in table mount. To change the motor block orientation, see “Change the motor block orientation”.
