FLAT LENS FROM LEUCO SAPPHIRE WITH FOCUS OF E WAVES Russian patent published in 2015 - IPC G02B1/02 G02B1/08

Abstract RU 2555183 C1

FIELD: physics.

SUBSTANCE: this flat lens is made from blank is made from high-temperature plastic straining of plate produced from Al₂O₃ crystal Z-cut. Mirror axis of said plate is aligned with that of male die with working surface described by 4^th degree polynomial y = Σ_Ka_kx^k, where y, x are coordinates of cross-section with centre at mirror axis, a_k are factors describing the focal length and lens depth at k = 1…4. Flat lens inlet and outlet surfaces are planes perpendicular to mirror axis of the blank and lens. Flat lens outlet surface and blank have common point at lens mirror axis. Outlet surface is defined by required depth of the flat lens.

EFFECT: lens for parallel light beam directed perpendicular to part inlet surface.
