The NEC GT06RLB is a wide, short-focus fixed-lens for professional installation projectors, including the discontinued GT6000 model. Its primary purpose is to project large, high-resolution images from a short distance, which is ideal for environments with limited space between the projector and the screen. The fixed focal length means it has no zoom function, but this simplicity allows for better light efficiency, higher contrast, and sharper image quality than many zoom lenses. With a throw ratio of 0.60:1, it is categorized as a short-throw lens, making it suitable for rear projection applications or installations in small auditoriums, conference rooms, or museums.
