摘要： A system for selectively adjusting an objective lens correction collar includes a gear ring sized and shaped to fit about a correction collar of an objective lens. The system also includes an adjustment mechanism that has a motor operably connected to a complementary gear configured to selectively engage and cause movement of the gear ring, thereby adjusting the correction collar.
