In a case of changing focus from an object at infinity to an object at the closest distance, the first lens group is immovable, and the second lens group and the fourth lens group are moved in an optical axis direction along different trajectories from each other. The third lens group is moved in a direction intersecting the optical axis to perform camera shake correction. In addition, predetermined conditional expressions (1) and (2) are satisfied.

摘要： An imaging system is provided for a precision machine vision inspection or metrology system. The imaging system optical path includes a variable magnification lens portion and a variable focal length lens portion. The variable magnification lens portion includes various magnification states (e.g., 0.5× to 100×, using interchangeable lenses, or the like.) The variable focal length lens portion (e.g., including a tunable acoustic gradient index of refraction (“TAG”) lens) is operated at different focal length scanning frequencies depending on the magnification state. A TAG lens operated in this manner provides a relatively consistent range of focus (e.g., corresponding to a number of depths of field) with various magnification lenses, without limiting the effective numerical aperture of the imaging system.
