What does Hanson mean by reconditioned?

Once an instrument has arrived on site, it will go through an extensive testing process and be cosmetically inspected. Following this, any repairs or updates required will then be undertaken by our skilled engineers in our newly built engineering workshop and any cosmetic repairs will be undertaken in our paint booth. We aim to meet expectations by ensuring that all our reconditioned instruments don’t just operate like new, they will look like new too.

Nidek RT-600 Refractor

  • Smooth and precise measurement of spherical and cylindrical features
    Measurement of spherical features can be made in the range between +16.75 and -19.00D; for cylindrical features, between 0 and -6.00D, each adjustable in increments of 0.25D. Even greater accuracy can be obtained by making measurements in 0.12D increments by using the auxiliary lenses, which permit an increased range of between +26.75 and -29.00D (Option) for spherical measurements, and up to -8.00 for cylindrical measurements. In addition, the spherical power quick forwarding dial can be used to make adjustments in 3.00D step intervals, resulting in efficient, as well as accurate, measurements.
  • Unique cross cylinder configuration
    Both the cylindrical axis and cross cylinder lens can be engaged, thanks to the unique Nidek configuration, which permits easy control with a simple turn of the cross cylinder knob. Three types of +-0.25D, +-0.37D, and +-0.50D cross cylinder lens are available. Both +-0.37D and +-0.50D are options.
  • Auxiliary lenses
    A full compliment of auxiliary lenses are built in, enabling any type of measurement.
  • Convergence system
    Shifting the convergence lever to the inside lets the patient be examined under optimum conditions.
