Patent ID: 7646848

Claim:
A goniometer ( 1 ) for measuring stresses and characterizing microstructure of particles, comprising: a frame ( 4 ), a measurement head ( 7 , 8 , 9 , 10 ) movably adapted to the frame ( 4 ) by a first linear movement unit ( 5 ), second linear movement unit ( 6 ) and a tilting movement unit ( 16 ), for performing measurement at a measurement point ( 31 ), wherein the axis of rotation ( 12 ) of the tilting movement unit ( 16 ) does not coincide with the measurement point ( 31 ), and the device has means ( 17 ) for creating arc-formed ( 30 ) movement of the measurement head ( 7 , 8 , 9 , 10 ) during the measurement with said movement units ( 5 , 6 , 16 ) without the use of a cradle under the measurement head.
