OPTICAL SUBASSEMBLY WITH A MOUNT WITH CONNECTION UNITS OF DIRECTED FLEXIBILITY

A thermally compensated optical subassembly having a rotationally symmetrical optical element and a monolithic mount with a rotationally symmetrical mounting ring, having an axis of symmetry, and at least three connection units. The optical element communicates with the mounting ring via the connection units, so as to be secured against tilting and fixed with respect to torsion. The connection units, in each instance, have three couplers which have a determined length ratio with respect to one another and are connected to one another and to the mounting ring and optical element such that defined conditions are met.
