Galilean systems are small, light-weight optical systems similar to telescopes. They are comprised of a positive objective lens and a negative ocular lens.
These spectacle magnifiers are calculated for a fixed working distance and also for a certain angle of convergence. Additional fine focusing and diopter setting is possible. Available in 3 magnifications for close-up work: 2.5x, 3x and 4x. Each spectacle is supplied complete with a leather zippered case to store the spectacle when not in use.
