A kinematic lens mount for kinematically mounting an optical element has a holder structure and three clamping units, each affixed to the holder structure and kinematically clamping a peripheral portion of the optical element. Each of these clamping units includes a flexure mount affixed to the holder structure and a spring assembly including a resilient member contacting the optical element. A lens seat is formed integrally with or attached to the flexure mount for supporting the peripheral portion of the optical element thereon. The flexure mount includes a pair of flexure devices. One end of each of these flexure devices is affixed to the holder structure. Each of these flexure devices may be of a pivot type, having an axis along which it is stiff and the axes of this pair of flexure devices intersect each other inside the peripheral portion of the optical element.
