METASURFACE PRIMARY LENS AND METASURFACE SECONDARY LENS, MANUFACTURING METHOD THEREOF, AND OPTICAL SYSTEM

摘要

Provided are a metasurface primary lens (1), a metasurface secondary lens (2), a manufacturing method for the same, and an optical system. The metasurface primary lens (1) is manufactured by means of the manufacturing method for said lens. The metasurface primary lens (1) comprises a transparent substrate (200). The transparent substrate (200) comprises a metasurface pattern of the primary lens (1) located on the transparent substrate (200). The metasurface of the primary lens (1) is configured with a pattern satisfying phase distribution of the primary lens (1), so as to reflect and focus an incident light reflected by the metasurface secondary lens (2) onto the metasurface primary lens (1).
