A device and method of compensating for the temperature dependence of a facet lens used for determining the topography of an eye. According to the invention, temperature sensors are present for determining the temperature of the facet lens. In addition, the temperature dependence of the beam angles of the beam bundles is stored in a control and evaluation unit, which, in addition to the temperature of the facet lens transmitted by the temperature sensors, are taken into account by the control and evaluation unit when evaluating the recordings of the image recording unit. The device and method are described in the context of facet lenses that are used to determine the topography of an eye. However, in principle, they are usable wherever an existing temperature dependence, in particular of optical components, should be compensated for.
