The present invention concerns an interference microscope and a method for operating an interference microscope, in particular a 4 microscope, standing wave field microscope, or I2M, I3M, or I5M microscope, at least one specimen support unit associated with the specimen being provided. Fibrous substrates treated according to this method and fibrous substrates treated with the aforementioned compositions are also disclosed. These assets are then automatically combined to render a completed multimedia object in which the defined transition is used to visually transition a first image or frame to a second image or frame. Various forms of devices for grasping are possible as alternatives, including a string, a tab and a tab with one or more finger-receiving holes. The method may further involve performing one or more actions with respect to at least one SUDF of the one or more SUDFs. A separation element is interposed between the mobile armatures and the corresponding polar extensions.
