The Sanyo LNS-W03E is a specialized short-fixed focal length lens engineered for select high-performance Sanyo projector models, designed to address installation scenarios requiring a large image from an exceptionally short throw distance. This lens category, often referred to as an ultra-short or very short throw lens, allows the projector to be positioned much closer to the screen than standard lenses—typically just inches or a few feet away. This capability is crucial in environments like classrooms, where it minimizes shadows cast by presenters, in digital signage installations with shallow depth, or in boardrooms where the projector can be discreetly mounted directly above or below the screen.

Optically, the LNS-W03E is constructed with precision glass elements to deliver a sharp, bright, and color-accurate image despite the extreme projection angle. It corrects for potential geometric distortions (like keystoning) inherent in short-throw applications, ensuring a perfectly rectangular and focused picture across the entire screen. The lens features a manual focus ring for final image tuning and is built to handle the high light output and thermal conditions of professional large-venue projectors without compromising optical performance or longevity.

This lens is an essential tool for AV system integrators and designers working within strict spatial constraints. By enabling a projector to fill a large screen from a position very near the wall, it opens up a wider range of mounting possibilities and contributes to a cleaner, more aesthetically pleasing installation. The Sanyo LNS-W03E provides a professional, reliable solution for achieving impressive visual displays in spatially challenging environments where traditional projection setups are impractical.
