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 ...

We present the design, fabrication and characterization of hydraulically-tunable hyperchromatic lenses for two-dimensional (2D) spectrally-resolved spectral imaging. These hyperchromatic lenses, ...

Waves close wavesVibrations that transfer energy from place to place without the transference of matter. - including sound and light - can be reflected at the boundary between two different materials.

A microlens that uses negative refraction to achieve a record focal length of 12 µm could benefit high-density imaging and optoelectronics systems. US researchers have engineered a concave photonic ...

US researchers have focused a plane microwave by a plano-concave lens fabricated from a photonic crystal specially designed to have negative refractive index and left-handed electro-magnetic ...
