Prefer to wait for the Nidek LM-7 – Auto Lensmeter – Used? Request availability and we’ll source one for you.
The Nidek LM-7 series Auto Lensmeter delivers advanced automated optical lens measurement for both spectacle and contact lenses. Utilizing a Hartmann sensor with 108 simultaneous measurement points, it offers highly accurate and rapid acquisition of sphere, cylinder, axis, addition (ADD), prism, pupillary distance (PD) and UV transmittance.
The instrument features automatic lens-type detection (single vision, bifocal, progressive), a vertical 5.7″ full-colour touchscreen interface, a “scale mode” for PD measurement, and sophisticated connectivity (USB, RS-232C, optional LAN/WLAN). The LM-7P version adds a built-in high-speed thermal printer with auto-cutter. With its modern design and premium optics, it is ideal for optometry clinics, dispensing labs and ophthalmic practices seeking precision, speed and connectivity.
