US Patent 9389488 Lens mounts with locking mechanisms

An optical assembly includes a lens mount. The lens mount includes a lens mount body with a threaded lens aperture extending axially therethrough. A ring extends from the lens mount body. The ring defines a lens locking aperture therethrough that is spaced axially apart from the lens aperture and is aligned with the lens aperture. The lens aperture and lens locking aperture are both threaded. A lens element is threaded into the lens aperture and lens locking aperture. A lock operatively connects the lens mount body to the ring for locking the lens element by flexure of the ring relative to the lens aperture.
