Electronic Lensometer Humphrey LA350 - Good

Humphrey LA350: High-Precision Optical Lens Analyzer for Professionals

The Humphrey LA350 is a state-of-the-art lensmeter designed for optical and ophthalmic professionals. This device provides fast and accurate neutralization of corrective lenses, whether progressive lenses, prism prescriptions or contact lenses. With its advanced technology, it allows reliable measurement of polycarbonate or high-index lenses without extensive training or complex manuals.

Its intuitive, icon-based interface guides the user through the neutralization process. It provides continuous feedback and automatically flags irregularities, such as lens aberrations or rapid power changes. One of the major innovations of the Humphrey LA350 is its ability to automatically calculate monocular and binocular pupillary distance (PD), eliminating the need for manual centering. This feature guarantees significant time savings and unmatched accuracy.

The instrument adapts to all lens materials thanks to scalable software. By simply entering the material's Abbe value, the device adjusts its calculations to provide optimal measurements. With a resolution of 640 x 480 pixels and a grayscale display, data readability is ensured. Its integrated printing system allows instant readings on thermal paper.

Built to last, the Humphrey LA350 is an ideal investment for opticians and eye care professionals. It guarantees reliability, precision and ease of use, thus improving the quality of optical services offered to patients.
