Condition & Warranty
Used. This Nidek LM-7 has been inspected and powered on, with the color touchscreen, Hartmann-sensor measurement, and lens marking mechanism confirmed in good working order; it shows cosmetic signs of prior clinical use. Every unit is tested before shipment. Covered by a 90-day warranty on parts and workmanship.
Nidek LM-7 Auto Lensmeter — Used Automated Lensmeter
The Nidek LM-7 auto lensmeter is a compact, vertically designed automated lensmeter built to speed up daily lens verification in any optical dispensary or pre-testing lane. At the heart of this used Nidek LM-7 auto lensmeter is a Hartmann sensor that reads 108 measurement points simultaneously inside the nosepiece, capturing sphere, cylinder, axis, ADD, and prism in a single quick step with strong repeatability. Placing a lens on the stage triggers automatic lens-type detection, so the instrument switches to the correct single-vision, bifocal, or progressive mode on its own.
Results appear on a vertical 5.7-inch color LCD touchscreen with an uncluttered layout, and the unit reads spectacle lenses across a sphere range of -25 to +25 D and a cylinder range of 0 to ±10 D. UV transmittance is displayed from 0 to 100% at a central wavelength of 365 nm, and the built-in scale mode measures monocular and binocular PD by aligning marked glasses to the on-screen scale. Data moves out through one RS-232C port and two USB ports for connection to an edger, refraction system, or EMR.
Independent testing supports the role of automated focimeters in reliable lens power verification — the National Library of Medicine reports on the accuracy of automated focimeters for measuring spectacle lens power.
Why Practices Choose the Nidek LM-7
- 108-point Hartmann sensor — simultaneous multi-point measurement for fast, repeatable sphere, cylinder, axis, ADD, and prism readings.
- Automatic lens-type detection — the instrument identifies single-vision, bifocal, and progressive lenses and switches modes without operator input.
- Vertical 5.7-inch color touchscreen — a space-saving footprint with a clear, tap-driven interface.
- UV transmittance measurement — reports UV-A (365 nm) transmittance from 0 to 100% for lens quality checks.
- Scale-mode PD measurement — monocular and binocular pupillary distance read directly on screen.
- Flexible data output — one RS-232C and two USB ports connect the LM-7 to edgers, refraction systems, and record software.

Clinical Applications
- Verifying incoming spectacle prescriptions before dispensing.
- Neutralizing single-vision, bifocal, and progressive lenses quickly.
- Confirming prism and axis on remakes and warranty claims.
- Checking UV transmittance and lens quality at intake.
- Measuring monocular and binocular PD from finished eyewear.
Who This Is For
- Optical dispensaries and retail optical shops handling high lens volume.
- Optometry and ophthalmology practices running an in-house pre-testing lane.
- Lens finishing labs that need reliable neutralization before edging.
- Mobile and satellite clinics needing a compact, all-in-one lensmeter.
