FIGURE 2.

This research system mechanically switches between either an anterior segment optical path (dark blue position) or a posterior segment optical path (lighter blue position) using a rotary solenoid. The switch in optical paths engages different optics to produce either an anterior segment volume (bottom left) or posterior segment volume (bottom right).
