TLDR
In this article, a photoelectric converter including a convergent lens with a transparent member having a refractive index distribution, in a cross section perpendicular to a travelling axis of light, is presented.Abstract:
Disclosed herein is a photoelectric converter including a convergent lens with a transparent member having a refractive index distribution, in a cross section perpendicular to a travelling axis of light, so as to substantially satisfy the equation: NR NO(1-AR2) WHEN A REFRACTIVE INDEX AT THE CENTER OF THE CROSS SECTION IS NO, A REFRACTIVE INDEX AT A DISTANCE R FROM THE CENTER IS NR AND A POSITIVE CONSTANT IS A.read more

Negative abbe number radial gradient index relay and use of same
TL;DR: In this paper, a radial gradient index of refraction (GRIN) optical relays are described for overcorrecting axial chromatic aberration. Butler et al. described a relay including a negative dispersion radial GRIN rod alone or in combination with simple homogeneous or GRIN lenses.

Gradient index miniature coupling lens
TL;DR: In this article, a miniature optical lens for coupling is fabricated from selected high rective index semiconductor material of uniform thickness, which can be used for coupling light energy from light emitting diodes and junction lasers as well as in semiconductor micro-optics within the visible and the infrared wavelengths.

Gradial zone lens and method of fabrication
TL;DR: In this article, a plano-plano (60, 70, 78, 90, 98, 106, 114) and planoconvex (76) refractive lenses are formed by separately, sequentially spin casting and polymerizing successive radial zones of the lens to produce optical phase differences of 2π between adjacent gradial zones.
