The RS-6698 surgical loupes are advanced Keplerian prism loupes on wire frame with non-prescription protective glasses. The Keplerian design provides better resolution and the field of view is larger than what could be achieved with standard Galilean optics. On the other hand, these loupes are heavier than our other ones and the working distance needs to be maintained more accurately.
Magnification 4 X
Working distance 420 mm (400-440 mm)
