ABSTRACT:
A combined structure includes a first member having at least a projection, e.g., a support, and a second member, e.g., an optical mirror, having a coefficient of thermal expansion different from that of the first member and combined cross-wise with the first member through a projection of the latter and by use of connecting members. One side wall surface of the projection of the first member and both side wall surfaces of the second member intersecting the former are bridge-connected by the connecting members at a height of a neutral plane of the second member which intersects the side wall surface of the projection of the first member. In case the first member has a plurality of projections, only those wall surfaces of the projections that face the same direction are bridge-connected to both side wall surfaces of the second member.
