A device for measuring the surface topography of a sample includes a projector which projects a structured image onto the surface of the sample. A camera observes the image projected onto the surface of the sample. A heating device applies a temperature ramp on the sample. A first optic device located on the optic axis of the projector modifies the image emitted by the projector and applies it on the sample. The first optic device includes several distinct lenses defining different magnifications. The lenses are fitted movable with respect to one another. A second optic device is located on the optic axis of the camera to modify the size of the observation area on the surface of the sample. The second optic device includes several distinct lenses presenting different magnifications. The lenses are fitted movable to define several observation areas of different sizes.
