The lens is produced by blocky, S-shaped “unit cells” a few millimeters wide that refract radio waves in particular directions. The roughly concave lens is formed from 4,000 of these cells.

Shanghai Optics Inc - Plano Concave LensesA plano concave lens is an optical lens with one concave surface and one flat surface. It has a negative focal length, and can be used for light projection, ...

ECOPTIK - Plano Concave Cylindrical LensA plano-concave cylindrical lens is used to expand light in on-axis. A negative cylindrical lens is able to diverge collimated input light away from a line.

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

When the polarization direction of the probe He-Ne laser beam was parallel to the LC director, it formed a concave lens in the DDLC. The beam diameter of the He-Ne laser beam was measured as a ...
