A cantilever assembly (1) comprises a cantilever (10) having a cantilever tip (11). The cantilever is mounted to a rigid support (12,120,121) and is provided on its back side with an area (110) of a high reflectance material having a boundary (111) sloping towards the support (12). The extensions (c, &Dgr;c) of the area (110) and of the boundary (111) towards the support fulfil the condition c/&Dgr;c≧1 wherein c denotes the extension of the area (110) of the high reflectance material in the direction towards the support (12), and &Dgr;c denotes the extension of the sloped boundary (111) of the area (110) of the high reflectance material in the direction towards the support (12). |
