Infrared gradient refractive index (GRIN) material lenses have attracted much attention due
to their continuously varying refractive index as a function of spatial coordinates in the …

While widely used in the visible, radial gradient refractive index (GRIN) lenses are still
elusive in the IR waveband. In this paper we introduce a new method based on spatially …

Compared with ordinary uniform lenses, the length and refractive index distribution of
gradient refractive index (GRIN) lenses can effectively correct aberration and chromatic …

New moldable, infrared (IR) transmitting glasses and diffusion-based gradient index (GRIN)
optical glasses enable simultaneous imaging across multiple wavebands including short …

Optical losses of chalcogenide negative curvature hollow-core fibers with hybrid cladding
elements were numerically investigated in this study. Microstructured cladding formed by the …

Chalcogenide glasses show a unique potential for creating gradient refractive index (GRIN)
lenses, which would reduce the size and weight of infrared thermal imaging system and …

The gradient refractive index (GRIN) lens is widely used in the visible band, but it is still
elusive in the infrared band. In this paper, we propose a new method of fabricating …

A polymer that has been used for the development of optical components and has had a
significant impact is polydimethylsiloxane (PDMS) due to its remarkable mechanical and …
