1. In combination:

  • a plurality of mounts;

    a frame, surrounding and supporting said mounts symmetrically about a first axis; and

    a case surrounding and rigidly attached to said frame at a set of points equal in number to the number of said mounts and said attachment points being equiangularly symetrically distributed about said first axis at angular positions substantially midway between said mounts;

    said case having a higher coefficient of thermal expansion than the coefficient of thermal expansion of said frame to cause the motions of said case and said frame under changes of temperature to compensate for each other and cause said mounts to remain substantially stationary over a range of temperatures.
