About the Sanyo LNS-W31A Zoom Projector Lens, 1.5x

The Sanyo LNS-W31A is a professional 1.5x zoom projection lens designed as an interchangeable accessory for specific models of Sanyo (and later, Panasonic) large-venue and installation-grade projectors. Its primary function is to provide optical flexibility in projector placement by offering a variable focal length, allowing installers to adjust the image size without physically moving the projector. With a 1.5x zoom ratio, this lens enables a moderate range of adjustment; for a given projection distance, the image size can be made approximately 1.5 times larger or smaller by rotating the zoom ring. This is crucial for fine-tuning the image to perfectly fit a fixed screen size in boardrooms, lecture halls, houses of worship, or control rooms where the projector's position may be constrained by architecture, cabling, or sightlines.

Constructed with high-quality glass elements and multi-layer coatings, the lens is engineered to maintain image sharpness, contrast, and color fidelity across its entire zoom range and aperture settings. It is designed to be compatible with projectors featuring a standardized lens mount and matching optical throw characteristics, typically Sanyo's "L" series or similar models known for their modular lens systems. The lens barrel includes manual control rings for zoom (adjusting image size) and focus (achieving a sharp image), allowing for precise calibration during installation. By using a dedicated zoom lens like the LNS-W31A instead of a fixed focal length lens, system integrators gain significant versatility, enabling a single projector model to serve a wider variety of room geometries and screen sizes without compromising on image quality.
