Marco RT 300 Phoroptor

The RT-300’s accessory knob is positioned next to the cylinder power/axis knob and all controls are within a hand’s breadth of each other. Cylinder power up to +-6.00D; sphere power from +16.75 to -19.00D. “Sure-grip” knurls on the control knobs make them easy to grasp. Combined with the convenient placement of the controls themselves, this helps reduce fatigue. Fully synchronized cross-cylinder is standard.

  • Fully synchronized cross cylinders
  • Anti reflective coated lens
  • Bi-loupe turret system
  • Large, legible high contrast number scales
  • Conveniently located knobs
  • Manual refractor
