摘要
The present invention is directed to a polarizing filter (20), comprising a plurality of areas (25), for passing light, each area (25) being separated from the others, wherein each of the areas (25) is a linear polarizer and at least two of the areas (25) have a different polarization axis. The present invention is further directed to an apparatus (1) for determining an orientation of a lens polarization axis of a polarized lens (31) and using said polarizing filter (20) as well as a method of determining an orientation of a lens polarization axis of a polarized lens (31) using said apparatus (1).
