Optical device with tubular housing, e.g. for telescopes or microscopes, has controlled deformation devices that cause controlled increases or reductions in wall diameter integrated into wall

摘要

The device has a tubular housing, one or more plane optical elements, a wall (11) forming a load bearing structure for the optical elements, which are transverse to the longitudinal direction and attached to the inner wall surface at points with controlled deformation devices that cause controlled increases or reductions in wall diameter and are integrated into the wall.
