  • Patent number: 11187871
    Abstract: A bipod flexure mount couples an optic to a base while isolating the optic from strain to resist wavefront error. The bipod flexure mount has a distal attachment pad to be coupled to the optic and a proximal attachment pad to be coupled to the base. A pair of beams extend between and couple the distal and proximal attachment pads. The distal attachment pad, the proximal attachment pad and the pair of beams are disposed in and define a planar layer with opposite planar surfaces that are substantially parallel. The bipod flexure mount is relatively flexible about four degrees of freedom and is relatively stiff about two degrees of freedom.
