Condition & Warranty
Used. This Nidek RT-5100 and SC-1600 digital refraction package has been fully tested and is in excellent working order. The phoropter head switches internal lenses instantly and silently, the console touchscreen and dial are highly responsive, and the SC-1600 LCD projects clear, high-contrast polarized optotypes. All communication links between the phoropter and the chart display are verified. The unit shows minor cosmetic signs of use, as expected for used automated clinical equipment. Covered by a 90-day warranty on parts and workmanship.
Nidek RT-5100 Auto Phoropter — Used with SC-1600 Polarized LCD Chart

This complete workstation pairs the phoropter with the Nidek SC-1600, a 17-inch SXGA LCD acuity chart that links directly to the refractor. When a chart is selected on the operator’s console, the SC-1600 updates instantly, creating a fully integrated refracting workflow. The chart’s polarization supports precise binocular testing, contrast charts are available at 25%, 12.5%, and 6%, and the working distance is selectable from 2.5 to 6 m to fit any exam room. With an ultra-slim optical head that preserves a 40-degree visual field, this used nidek rt-5100 package brings a modern, tech-forward refraction standard to any practice.
Research published in the National Library of Medicine found that automated subjective refraction performed with a computer-controlled motorized phoropter produces results clinically comparable to conventional manual refraction, supporting the shift to motorized refraction lanes in high-volume settings.
Why Practices Choose the Nidek RT-5100 & SC-1600
- Synchronized chart integration — selecting an exam protocol on the RT-5100 console automatically changes the optotypes on the SC-1600 screen, with no separate remote juggling.
- Smooth, speedy, silent lens drive — internal lens changes happen instantly, limiting patient accommodation shifts and speeding up subjective preference choices.
- Polarized LCD charts — the SC-1600 polarizes charts for phoria, fixation disparity, and binocular balance testing without trial-frame filters.
- Intuitive operator console — a tiltable color LCD touchscreen tracks exam progress logically, with on-screen assist guidance and a responsive physical dial for rapid power changes.
- One-touch prescription comparison — toggle instantly between the patient’s old correction, objective data, and the new subjective findings to demonstrate the improvement.
- Pre-test data import — receives data from auto refractors and auto lensmeters so the starting test values populate automatically, minimizing transcription errors.
- Ultra-slim optic head — the compact phoropter body maintains a 40-degree visual field and an open, comfortable feel for the patient throughout the exam.
Clinical Applications
- High-efficiency subjective refractions establishing rapid, precise sphere, cylinder, and axis values for corrective lenses.
- Polarized binocular vision testing including phoria, duction, stereopsis, and binocular balance diagnostics on the integrated LCD chart.
- Contrast sensitivity screening at 25%, 12.5%, and 6% contrast to assess subtle visual function loss in early cataract, glaucoma, or post-refractive patients.
- Premium lane upgrades modernizing the core subjective lane with a seamless, high-tech diagnostic presentation that builds patient trust.
Who This Is For
- High-volume optometrists and ophthalmologists who want to maximize patient throughput while preserving comfort and exam precision.
- Modern multi-doctor clinics that need standardized, electronic refractions integrating smoothly with pre-test instruments and EMR workflows.
- Private practices looking to eliminate the physical strain of manual refractor dials by stepping up to an automated Nidek platform.
