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.
