摘要

polierteller (10) for a tool (12) for finishing of optically effective surfaces (cc, cx) lenses (l), with a centre axis (m) of particular body (14).the one in relation to the basic body (14) softer interlayer (16) from a flexible material is attached to a poliermitteltru00e4ger (18) can be accessed, characterizedthe intermediate layer (16), at least two areas of different hardness inin the direction of the central axis (m) in a row are arranged by each other and different schaumstoffschichten (20, 22) are trainedwith the body (14) adjacent schaumstoffschicht (20) which is the schaumstoffschicht (22) on which the poliermitteltru00e4ger (18) on it, and withas for the case of a ganzflu00e4chigen compression, the static e - module the tougher schaumstoffschicht (22) between 0.40 and 1.50 n / mm.2is, while the static e - module the softer schaumstoffschicht (20) between 0.25 and 0.45 n / mm.2.
