ABSTRACT:
A mount for use by optical elements in a laser tooling alignment system. The mount provides a high degree of isolation from external rotational disturbances about any horizontal axis (i.e., pitch and roll) by retaining optical components in a fixed relationship to the local gravity gradient. The mount is a passive gravity referencing two stage, fluid damped pendulum. When a constant deviation optic (e.g. pentaprism beam splitter) is attached to the mount, effective isolation from yaw disturbances is also achieved.
