Optics:

Two clearly neural knobs on either side of the optical head allow the user to easily switch between a pair of fixed magnifications. Multiple combinations of magnification available to include 10/20x, 10/30x, 20/40x, 15/30x, 15/45x, 30/60x, 10/60x, and 40/80x. 

Dual, side-mounted knobs clearly mark the magnification value and allow the user to quickly identify what magnification they are on. Highly polished lenses create a smooth flat field of view with crisp, shape resolution. Parfocality is maintained when switching between high and low magnifications to prevent constant searching and refocusing of sample.

Eyepieces:

10X super-widefield eyepieces with interpupillary and diopter adjustments to correct for user-specific eyesight.
