A novel tunable multifocal liquid crystal microlens array (TMLCMA) can be operated in convex and concave modes through driving schemes. Under applied voltages, the focal length of microlens radially changes from the TMLCMA border to the center, showing the multifocal property. Axially-symmetric LC reorientation allows the TMLCMA to be polarization-insensitive.
