The EIKI LNS-W34 is an extreme wide-angle, fixed focal length lens designed for ultra-short-throw projection applications with compatible EIKI and select other large-venue projectors. With a remarkably low throw ratio of 0.8:1, this lens enables the projector to be positioned exceptionally close to the screen—often just inches away—while still projecting a very large image. This capability is critical for installations in spaces with severe depth limitations, such as small meeting rooms, museum exhibits, retail displays, and rear-projection cubes where the projector must be housed within a shallow enclosure directly behind the screen. The fixed focal length means the image size can only be adjusted by physically moving the projector, but this design often yields superior optical performance and brightness consistency compared to zoom lenses in this class.

The lens is constructed with high-quality glass elements to minimize geometric distortion (pincushion or barrel distortion) and chromatic aberration, which are common challenges with extreme wide-angle optics. This ensures a sharp, color-accurate image across the entire screen, even in the corners. It is engineered to handle the high light output and thermal load of professional projectors without introducing focus drift or color fringing. The lens typically includes manual focus and lens shift adjustments (vertical and horizontal), allowing installers to fine-tune the image alignment perfectly onto the screen surface. Its robust housing ensures the precision optical alignment is maintained over time.

Integrating the EIKI LNS-W34 lens solves one of the most difficult spatial challenges in projection system design. By drastically reducing the required throw distance, it opens up projection possibilities in environments previously considered unsuitable. For system designers, this lens is a specialized tool that allows for the creation of large, immersive, and seamless visual displays in the most space-constrained installations, making it a key component for creative and practical projection mapping, digital signage, and compact presentation systems.
