A scanning system of a position measuring device for photo-electric scanning of a measuring graduation, the scanning system including a support carrying measuring components, an adapter including a scanning graduation in a graduation plane and a holder that holds the support on the adapter. The holder is structured so that the support is stationarily positioned on the adapter in six degrees of freedom, but compensates thermally caused expansion of the support in relation to the adapter in a first coordinate direction and a second direction which define the graduation plane.
