Biomimetic 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 کاملDesigning the optimal Fresnel lenses by using Zemax software
In this paper, the optimal Fresnel lenses are designed by Zemax software.The fundamental problem of the Fresnel lenses is the beam divergence, which wasresolved by decreeing the output stain diameter on the image plane. For this purpose,two types of radial and cylindrical Fresnel lenses are simulated with different groovesusing Global and Hammer optimization methods. The minimum output stain di...
متن کاملPrimary aberration coefficients for axial gradient-index lenses
As for homogeneous lenses, for axial gradients the analysis of the Seidel and chromatic aberration coefficients can be very useful in lens design. However, at present few commercial optical design programs list the Seidel aberrations of GRIN lenses and none of them lists the chromatic aberrations. In order to facilitate the computer implementation of the chromatic aberrations of axial GRIN lens...
متن کاملBirefringent properties of diametrically loaded gradient-index lenses.
Gradient-index (GRIN) lenses have been widely used as collimators in various fiber-optic sensors and as optical coupling devices in components designed for optical communication systems. However, relatively little attention has been paid to the birefringent properties of GRIN lenses and the potential for using them as photoelastic sensing elements in optical transducers. Analytical and experime...
متن کاملNew ray-tracing method for radial gradient-index lenses
A new method to derive algebraic formulae for tracing skew rays in radial gradient-index media is described. We obtained power series for the ray position and direction, optical path length and coordinates of the intersection point of the curved ray with the spherical end surface of the GRIN lens. All these formulae include the effects of terms up to the eighth power of the radius in the refrac...
