PCT No. PCT/DE92/00110 Sec. 371 Date Nov. 18, 1992 Sec. 102(e) Date Nov. 18, 1992 PCT Filed Feb. 15, 1992 PCT Pub. No. WO92/15031 PCT Pub. Date Sep. 3, 1992.The described joint (1, 3, 2) consists of at least three joint parts preferably with different material composition and thus different thermal expansion coefficients alpha . For optimum compensation of the deformation differences acting predominantly radially, which result with a temperature change, it is proposed to provide between a first joint part-for example an optical lens (1)-and a second joint part-for example a lens mounting (2)-at least one further joint part as intermediate ring (3), the ring thickness-dimensioning thereof and the material selection thereof (thermal expansion coefficient alpha R) being carried out in such a manner that the aforementioned deformation phenomena, which are material-specific and caused by temperature change, in the joint (1, 3, 2) compensate themselves in such a manner that a stress-free or low-stress mounting, for example of microoptics (1) for use in polarization-optical instruments, can be realized.
