A combined micro-objective lens for optical disc use has been developed. The lens consists of a thin relief diffraction grating film and a planoconvex glass substrate. The combined lens, which is called the spherical grating lens (SGL), is inherently a spherical lens, but has some interesting...
Concentration ratio and spherical aberration for Fresnel lens with spherical facets are also compared with those of plano-convex lens and conventional Fresnel lens with triangular facets. Furthermore, the present mathematical model is validated with SolTrace model and with the experimental study conducted...

First, it puts forth the idea of a concave-plano metamaterial lens designed with transformation optics as a solution to the monocentric lens' reimaging problem. In support of this idea, it provides an example of a design of a particular concave-plano reimager for a monocentric lens with a ...
2.2. Lens Design In the paraxial approximation for a thin plano-convex lens, the focal length is𝑓=𝑅/(𝑛−1)f=R/(n−1), where𝑅Ris the radius of the membrane curvature and𝑛nis the refractive index of the liquid. For a given liquid, the focal length is defined by the ...
To ensure the accuracy of the design calculations, the Gaussian light field passing through the micro-lens is divided into two parts: the lens surface and the lens substrate. This division is based on the structure of the micro-lens [18]. This design utilizes a plano-convex micro-lens, as...
