Abstract: The invention uses a laser frame which has a central opening about its sensing axis. There is a structural support member in the shape of two substantially conical frustums attached together at their largest diameter portions, with their axes coaxial, and attached to the periphery of the central opening of the frame. The support member is slotted with axially and radially directed slots to form therebetween axially and radially directed struts. The struts have surfaces at their smallest diameter portions for attachment to a post member. The angles of the frustums and the struts are such that when the support member is attached to a post member, thermal expansion of such post member would produce substantially pure bending of the struts.
