The accessory T-BTP extends the advantages of the ball-on-three-plates setup to the temperature range of -160 to 600 °C. Further, an optimization of the self-aligning mechanisms broadens the range of the applicable normal forces. The normal force range acting on the specimens is expanded down to 0.1 N. Also as a new feature, the spring stiffness in z-direction is adjustable.
