Abstract:

Autofocus (AF) optical arrangements and assemblies including a voice coil motor (VCM) are disclosed. An example optical assembly for a focusing lens includes: a front lens group disposed along an optical axis configured to receive light from the object of interest and configured to correct for aberrations of a first image projected by the front lens group; an aperture disposed along an optical axis configured to receive light from the front lens group therethrough along the optical axis; a moveable focus lens to receive light through the aperture; a VCM configured to move the focus lens to focus the optical assembly; and a back lens group disposed along the optical axis configured to receive light from the focus lens and further configured to correct for field curvature.
