Beschreibung
Zusammenfassung:A mirror socket (112, 112A, 112B, 112C, 112D, 112E, 112F, 112G, 112H, 112I, 112J, 112K, 112L, 112M, 112N, 112O, 114, 116) for an optical element (102, 102'), comprising a centre axis (126), a first spatial direction (x) oriented perpendicular to the centre axis (126) and a second spatial direction (y) oriented perpendicular to the centre axis (126) and perpendicular to the first spatial direction (x), wherein the mirror socket (112, 112A, 112B, 112C, 112D, 112E, 112F, 112G, 112H, 112I, 112J, 112K, 112L, 112M, 112N, 112O, 114, 116) has a first stiffness viewed in the first spatial direction (x) and a second stiffness viewed in the second spatial direction (y) and wherein the first stiffness and the second stiffness have different magnitudes.
