The NEC GT06RLB is a professional, ultra-wide, short-focus fixed lens designed as an accessory for compatible NEC installation projectors, enabling them to produce exceptionally large images from an extremely short throw distance. With a very low fixed throw ratio, this lens allows the projector to be positioned just inches to a few feet from the projection surface, making it ideal for applications where space is severely limited or where presenters need to stand close to the screen without casting shadows. Common applications include interactive whiteboard setups in classrooms, compact meeting rooms, museum exhibits, and immersive retail displays. The lens is engineered with high-quality, multi-element glass optics to minimize distortion and maintain edge-to-edge sharpness, which is critical when projecting at such a wide angle, as optical imperfections become more pronounced.

The lens features a robust, all-metal housing that ensures precise alignment and durability within the projector's interchangeable lens system. Installation involves swapping the projector's standard lens with the GT06RLB, a process that typically requires loosening a locking ring or lever, aligning alignment marks, and securing the new lens in place. Once installed, the fixed focal length means the image size can only be adjusted by physically moving the projector closer to or farther from the screen, offering a simple, reliable setup once the optimal position is determined. The large front lens element is essential for capturing and projecting the wide cone of light needed to fill a large screen from a short distance, maintaining brightness uniformity across the entire image.

This accessory lens exemplifies the modularity of professional installation projectors, allowing systems integrators to tailor the projection system precisely to the room's physical constraints. By enabling large-scale projection in tight spaces, the NEC GT06RLB Wide Short Focus Fixed Lens solves a common architectural challenge, transforming confined areas into dynamic presentation or display environments. Its specialized optical design ensures that the benefits of short-throw projection—reduced shadow interference and space efficiency—are achieved without compromising on image quality, clarity, or brightness.
