From: Development of a novel multifocal lens using a polarization directed flat lens: possible candidate for a multifocal intraocular lens

Fig. 7

Polarization-directed flat (PDF) lens used for digital single-lens reflex (DSLR) camera test. This PDF lens has a focal length of +/− 500 mm (+/− 2 D) depending on the polarization state of the incidental light and allows some of the light to pass through without refraction. Combining this PDF lens with an achromatic lens (focal length 100 mm, + 10 D) results in a trifocal lens (+ 8, 10, 12 D)
