Marco RT 300 Refractor

The Marco RT 300 Refractor features sealed in rear with replaceable plano lens.  Fully synchronized cross cylinders, or optional split- image cross cylinders. Anti reflective coating on lenses. Near tests. Bi-loupe turret system. Large, legible high contrast number scales. Selection of auxiliary lenses. Conveniently located knobs. Manual refractor.

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. Large high-contrast numbers on the instrument scales make them easy to read even in subdued light.
