The Agile Temperature Sample Mount provides the solution for the highest level of positional stability for step-static and dynamic temperature changes from 4K to 350K while improving the speed to each set point. The unique position stabilizing support structure optimizes stage mechanical stiffness and rigidity while providing the thermal performance required for fast temperature changes. The structure reduces thermal contraction to below 30µm over the entire temperature range from less than 4K to 350K. This technology eliminates the need to re-focus after small temperature changes. Ultimately, you can be confident that an optimized focus will remain stable throughout a measurement.
