ABSTRACT:
A holder for an optical device such as a lens includes a frame and a plurality of arms pivotably attached to the frame. A resilient member urges the arms toward a closed position in which the arms meet at a common center within the frame. Linking members insure that the arms move simultaneously. The arms are moved away from the common point to accept and secure the optical device.
