Radiation punctiform focusing device for use in beam shaping optics, has interface defined by solution of system of equations, and optical medium whose refractive index differs from refractive index of materials

摘要

The device has an optical medium arranged along an optical axis behind an optical interface (S2). A light emitting surface and the interface are arranged in a paraxial distance to each other, and the interface and a pixel unit (PB) are arranged in another paraxial distance to one another. The interface is defined by solution of system of equations,. A refractive index (n1) of the medium differs from a refractive index (n2) of materials arranged between a rib waveguide (12) and the interface.
