Fabrication of Polymeric, Nanolayered, Spherical, Gradient Refractive Index (GRIN) Lenses
A nanolayered polymer films fabrication approach creating Gradient Refractive INdex (GRIN) lenses with designer RI distribution profiles is reviewed. Fabricated GRIN examples are presented demonstrating unparalleled RI profile design freedom and scalable optic size. OCIS codes: (080.0080) Geometric Optics; (160.0160) Materials
متن کاملContribution of shape and gradient refractive index to the spherical aberration of isolated human lenses.
PURPOSE To estimate the contribution of 3-dimensional (3D) lens geometry and gradient refractive index (GRIN) to the lens spherical aberration (SA) with age. METHODS A total of 35 donor human lenses (19-71 years) were imaged with 3D-spectral optical coherence tomography (sOCT). Paraxial and nonparaxial back focal length were measured with laser ray tracing (LRT). The parameters of a 4-variabl...
متن کاملBiomimetic Gradient Index (GRIN) Lenses
A new class of hierarchically structured polymer optical materials possessing an internal refractive index gradient that mimics biological optical materials is described. The new materials permit the fabrication of gradient refractive index (GRIN) lenses with an unprecedented variety of index gradients. Gradients with different functional forms in both the radial and axial directions have been ...
متن کاملInfluence of shape and gradient refractive index in the accommodative changes of spherical aberration in nonhuman primate crystalline lenses.
PURPOSE To estimate changes in surface shape and gradient refractive index (GRIN) profile in primate lenses as a function of accommodation. To quantify the contribution of surface shape and GRIN to spherical aberration changes with accommodation. METHODS Crystalline lenses from 15 cynomolgus monkeys were studied in vitro under different levels of accommodation produced by a stretching system....
متن کاملMechanics and refractive power optimization of tunable acoustic gradient lenses
Tunable acoustic gradient index TAG lenses create tunable multiscale Bessel beams. These lenses are fluid-filled cylindrical cavities within which an acoustic radial standing wave is excited. This standing wave modulates the density, and thereby the refractive index within the lens. Spatial gradients in the refractive index can be used for lensing. A predictive model for the steady-state fluid ...
