1. Measuring head for use in radiant energy flash measuring of the thermal diffusivity of heterogeneous samples under employment of a probe beam generated by a radiant energy generating means and a detector means for detecting a temperature rise of said sample, comprisinga sample holder means for receiving said sample, wherein said sample holder means is movable in at least one direction perpendicular to the optical axis of said probe beam, a radiant energy input means for focusing said probe beam to said sample, and an adjustable viewing head for shifting a detector probe spot from a first position on said sample to a second position on said sample, wherein said radiant energy input means is arranged on one side of said sample holder means while said adjustable viewing head is arranged on the opposite side of said sample holder means.
