Abstract
A kinematic optical mounting assembly secures an optical element to a base. A plurality of first bracket assemblies and second bracket assemblies are secured to the base and engage the optical element. Each first bracket assembly constrains the optical element from movement relative to the base in a direction substantially parallel to an axis of the base. Each second bracket assembly constrains the optical element from movement relative to the base in a direction substantially perpendicular to the axis of the base and substantially tangential to a periphery of the base. Six independent bracket assemblies constrain the optical element in six degrees of freedom to provide kinematic constraint without bending moments.
