The Barco R9862005 TLD+ Ultra Short Zoom lens is a specialized, high-brightness optical assembly engineered for flagship 3-chip DLP projectors within Barco's large-venue and installation series. This lens is characterized by its ultra-short throw capability, with a zoom ratio ranging from 1.26:1 to 1.61:1 when used with projectors featuring a native SXGA+ (1400x1050) resolution. This optical design allows for the projection of very large images from an exceptionally short distance between the projector and the screen, making it an indispensable solution for spaces with severe physical constraints. It is ideally suited for control rooms, simulation facilities, boardrooms, and immersive environments where the projector must be mounted close to the display surface to avoid shadows, minimize presenter interference, or fit within tight architectural confines, all while delivering a massive, brilliant picture.

Constructed with precision-ground glass elements and advanced multi-layer coatings, the TLD+ Ultra Short Zoom lens maximizes light throughput and ensures exceptional image fidelity. Its optical formula is meticulously corrected to minimize geometric distortion, color fringing, and focus falloff at the edges, which are common challenges with ultra-short-throw designs. The result is edge-to-edge sharpness, uniform brightness, and accurate color reproduction across the entire projected canvas. The lens supports the high luminous output of its companion laser phosphor or xenon-based projectors without introducing thermal focus drift, ensuring stable performance during continuous 24/7 operation. The housing is sealed to protect the delicate internal optics from dust, a critical feature for maintaining performance in demanding environments.

The lens incorporates motorized zoom, focus, and lens shift functions, allowing for remote or automated adjustments via the projector's control system. This capability simplifies installation and calibration, enabling fine-tuning of image size, sharpness, and position after the projector is mounted. As part of Barco's comprehensive lens ecosystem, the R9862005 TLD+ offers system designers a powerful tool to overcome spatial limitations without compromising on image quality or brightness. It enables creative installation possibilities, such as rear projection in shallow cabinets or front projection in rooms with low ceilings, providing the flexibility needed to meet the exacting requirements of high-stakes professional visualization applications.
