The Barco R9862000 HB TLD+ lens is a specialized, high-brightness, short-throw optical assembly engineered for high-performance DLP projectors within Barco's professional installation and large-venue series. This lens is designed to work specifically with high-lumen laser phosphor or xenon-based light sources, facilitating the projection of large, brilliant images from a relatively short distance to the screen. Featuring a throw ratio of 0.67:1 (with a variant ratio of 0.73:1 when used with SXGA+ native resolution projectors), it is classified as a short-throw lens, enabling it to produce expansive displays in space-constrained environments such as control rooms, corporate lobbies, simulation facilities, and auditoriums where the projector cannot be positioned far from the screen. Its optical design is meticulously corrected for geometric distortion and color fringing, ensuring edge-to-edge sharpness and uniform brightness across the entire projected image, which is critical for multi-projector blended arrays and mission-critical visualization applications.

Constructed with precision-ground glass elements and multi-layer anti-reflective coatings, the TLD+ lens maximizes light throughput and minimizes internal reflections that could reduce contrast or cause flare. The lens supports high native resolutions, including SXGA+ and WUXGA, and is optimized to handle the intense light output of its companion projectors without compromising focus stability or image integrity over time. The robust, sealed housing protects the delicate internal optics from dust and particulate contamination, a vital feature for maintaining performance in 24/7 operational environments like network operation centers or command and control rooms. The lens is designed for integration into motorized lens shift systems, allowing for remote or automated adjustment of the projected image's position (vertical and horizontal shift), which greatly simplifies installation and calibration, especially in challenging or inaccessible mounting locations.

As a key component within a professional projection ecosystem, the Barco HB TLD+ 0.67:1 lens is part of a family of interchangeable optics that provide system designers with flexibility. Its specific throw characteristic allows for creative installation solutions, such as placing projectors closer to the screen to reduce shadow interference from presenters or to fit within shallow ceiling voids. The lens maintains precise compatibility with designated Barco projector models, ensuring optimal performance in terms of light utilization, color uniformity, and focus across the entire image circle. This professional lens exemplifies Barco's commitment to optical excellence, providing the critical link between a powerful projector light engine and a flawless, large-format display where precision, reliability, and image quality are non-negotiable.
