Refraction is the change in direction of light when it passes from one medium to another. The working of a lens is based on the refraction of light when they pass through it. Lens is a transparent ...

Although many studies on graded index (GRIN) lenses have been reported over the past several years, it is extremely difficult to find reports that have used polymer GRIN lenses in an atmosphere ...

A research team develops a transparent silicon without visible light loss by controlling the silicon atomic structure. A POSTECH research team has developed a transparent amorphous silicon that ...

Light is refracted when it enters a material like water or glass. Depending on the density of the material, light will reduce in speed as it travels through, causing it to change direction. Ray ...

(Nanowerk News) A POSTECH research team has developed a transparent amorphous silicon that transmits visible light - which permits us to distinguish the colors of objects - enabling the development of ...
