The Hitachi UL-705 is a specialized ultra long throw zoom lens engineered to project large, bright images over considerable distances, making it an essential solution for venues with deep auditoriums, high ceilings, or challenging installation constraints. This optical accessory is designed for compatibility with specific large-venue installation projectors, transforming their capabilities to serve applications such as large houses of worship, university lecture halls, performing arts centers, and command-and-control rooms where the projection booth or mounting point is far from the screen. Its sophisticated multi-element glass optical assembly is precision-crafted to maintain high resolution, contrast, and color fidelity across the entire zoom range, ensuring a sharp image even when projected from the back of a very long room.

Featuring a motorized 1.7x zoom ratio, this lens provides significant operational flexibility, allowing integrators to fine-tune the image size remotely during installation and calibration without physically moving the projector. The internal lens elements are coated with advanced multi-layer anti-reflective coatings to maximize light transmission and minimize internal flare and ghosting, preserving the projector's native brightness and contrast specifications. The robust, sealed housing is built to maintain precise optical alignment and protect sensitive components from dust infiltration, which is critical for the reliability expected in permanent, high-value installations that operate for thousands of hours.

The UL-705's optical design meticulously corrects for chromatic and geometric aberrations, delivering edge-to-edge focus uniformity and minimal distortion. It supports high-resolution native signals, ensuring that fine details in data, graphics, or video content are rendered with clarity from the front row to the last. By enabling projection from extreme distances, this lens solves critical site-specific challenges, allowing for cleaner architectural integration of AV equipment and reducing the need for complex, costly structural modifications. It represents a professional-grade optical tool that extends the functional reach of compatible projectors, guaranteeing a high-quality visual experience in the most demanding large-venue scenarios.
