Optical element back flexible supporting structure

The invention belongs to the technical field of precision optical machine design, and discloses an optical element back flexible supporting structure which comprises a mounting base and a flexible support, the bottom of the flexible support is connected with the mounting base, and an optical element is arranged above the flexible support; a plurality of flexible units are arranged on the flexiblesupport, each flexible unit comprises two arc-shaped through grooves, and the two arc-shaped through grooves are oppositely arranged and separated by a group of thin-wall structures to form a flexiblestructure with a cylinder in the middle and two arc-shaped through grooves in the periphery; and each thin-wall structure comprises two thin-wall bodies, and the plane where the two thin-wall bodiesare located is perpendicular to the radius of the flexible support penetrating through the center of the flexible unit where the two thin-wall bodies are located. The supporting structure is simple instructural form and easy to
