Nidek LM-500 Auto Lensmeter — Used Auto Lensmeter
The Nidek LM-500 auto lensmeter delivers fast, repeatable neutralization of single vision, bifocal, and progressive addition lenses (PAL) in a compact desktop footprint. A Hartmann sensor sampling 108 measurement points within the nosepiece captures the full lens prescription in a single 0.085-second reading, producing diopter, cylinder, axis, ADD, prism, and PD data with minimal operator alignment. The 535 nm green measurement wavelength reduces dispersion error in high-index spectacle lenses, so the LM-500 reports a clean spherical equivalent without manual Abbe-value correction.
Practical ergonomics round out the package. A tiltable monochrome LCD lets the operator adjust the viewing angle for seated or standing use, and the automated lens-type detection guides the technician through distance, near, and progressive zones with minimal training. The result is a workhorse auto lensometer that fits cleanly into a busy dispensary, exam pre-test station, or mobile screening kit.
For clinical background on lensmeter use in spectacle prescription verification, the National Library of Medicine (StatPearls — Lensometry) reviews how automated lensmeters resolve sphere, cylinder, axis, prism, and addition power for routine and complex prescriptions.
Why Practices Choose the Nidek LM-500 Auto Lensmeter

- 108-point Hartmann sensor — simultaneous wavefront sampling across the nosepiece captures the full prescription in a single 0.085-second reading, without the lens-positioning sensitivity of older single-point designs.
- Green 535 nm measurement wavelength — reduces chromatic dispersion error on high-index and Trivex spectacle lenses, so spherical equivalent values come out clean without manual Abbe compensation.
- Progressive addition lens (PAL) handling — automated zone detection walks the operator through distance, near, and add measurements, flagging power transitions that single-vision lensmeters miss.
- Compact desktop footprint — 180 × 185 × 366 mm and 3.5 kg make the LM-500 easy to fit into a pre-test station, dispensary counter, or mobile screening cart.
- Tiltable monochrome LCD — viewing angle adjusts for seated or standing operators; readouts stay readable under typical clinic lighting.
- Wide measurement ranges — sphere ±25 D, cylinder 0–±9.99 D, axis 0–180°, addition 0–±9.99 D, and prism 0–15Δ cover the prescriptions encountered in everyday optical work.
- PD measurement built in — interpupillary distance is captured alongside the prescription for a complete dispensing data set.
- Tested and cleaned before shipping — every unit ships in confirmed working order with a 90-day parts-and-workmanship warranty.
Clinical Applications
- Spectacle prescription verification — reading existing eyewear at the start of an exam to compare against subjective refraction.
- Progressive lens dispensing — confirming distance and add power before handing finished PALs to the patient.
- Contact lens power check — quick verification of soft or hard contact lens labels and trial lens accuracy.
- Mobile screening and outreach — compact enough for community vision events, school screening, and travel clinics.
- Optical lab and dispensary QA — verifying job tickets and finished spectacle lenses before patient pick-up.
Who This Is For
- Optical dispensaries and full-service eyewear retailers verifying finished prescriptions.
- Optometry and ophthalmology practices needing a reliable pre-test lensmeter at the front desk or in the exam lane.
- Mobile screening programs and school vision teams looking for a lightweight, transportable auto lensometer.
- Buyers replacing an aging manual lensometer with a faster automated reading workflow.
