The Hitachi FL-701 is a precision-engineered fixed focal length lens designed specifically for short-throw projection applications with compatible large-venue projectors. Its optical design is optimized to produce a large, bright image from a very short distance between the projector and the screen, making it an essential component for installations where space constraints are a primary concern. By utilizing this lens, system integrators can place the projector much closer to the screen than with a standard zoom lens, effectively minimizing shadows and reducing presenter glare, which is crucial in environments like classrooms, boardrooms, and control rooms where presenters frequently interact with the displayed content.

Constructed with high-grade glass elements, the FL-701 lens is built to deliver sharp, color-accurate images across the entire projection surface without the distortion often associated with extreme short-throw optics. It maintains the high brightness output and resolution capabilities of its host projector, ensuring that image quality is not compromised for the sake of installation flexibility. The lens features a manual focus ring for fine-tuning image clarity and is designed for secure, reliable mounting onto the projector's lens interface, ensuring stable alignment over long-term use.

This specialized lens solves significant geometric challenges in fixed installation AV design. It enables projectors to be installed in tight spaces, such as above a whiteboard in a classroom or directly beneath a screen in a lobby, where a standard lens would be impractical. The Hitachi FL-701 is a professional tool that expands the possibilities for system designers, allowing them to meet specific throw ratio requirements and achieve desired screen sizes in spatially constrained environments without sacrificing optical performance.
