Lightweight Kinematic Optical Mount for Vibration and Shock Environments

DoD optical systems often must provide precision static and dynamic alignment performance in the presence of harsh operating conditions that include mechanical shock and vibration as well extreme thermal environments. Optical elements such as mirrors or lenses are integrated into these systems with mechanical mounts. The objective of this effort is the development of a lightweight kinematic optical mount that provides straightforward optical alignment with integrated passive vibration and shock response mitigation. Lightweight means lighter weight than conventional devices. Kinematic mounting provides relief from static strains in a sensitive element imparted by thermal mismatch between structural components. Passive vibration/shock suppression allows improved system performance by reducing environment-induced jitter in the optical train. The goal is a mount design that combines three design targets: light weight, kinematic mounting, and reduced structural dynamics. This mount will be suitable for integration into existing optical systems but will also target new Commercial and DoD products for improved performance in applications that are sensitive to environmental disturbances and require easier adjustment than existing mounts.
