Loupe On Wire Frame With Glasses. 4X Magnification, 340mm Working Distance
?
The RS-6694 surgical loupes are advanced Keplerian prism loupes on wire frame with non-prescription protective glasses. The Keplerian design provides great resolution. 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.
?
The double-hinge design allows vertical adjustments for the perfect positioning of the optical pieces in front of the eye. The flip-up feature allows quick switching between normal and magnified view.
