Many interesting phenomena emerge at cryogenic temperatures, and often, additional or new information about a sample can be obtained with temperature-dependent measurements. This variable temperature Raman microscope system is optimized for high collection efficiency and throughput, offering an automated and controlled environment for characterizing materials with standard spectroscopic techniques.
Experimental Benefits
- Explore temperature-dependent phase transitions, frequency shifts, and linewidth sharpening with precise sample temperature control
- Obtain spectra at user defined intervals through the entire range (4K – 525K). A full set can be obtained in about one hour
- Generate precise Raman maps with low thermal-mechanical drift
- Acquire a full material property profile with simultaneous temperature-dependent spectroscopic and electrical measurements
- Measure weakly emitting materials efficiently with the integrated high NA optics
Measurement Techniques
- Raman Microscopy and Imaging
- Photoluminescence Spectroscopy and Imaging
- Absorption Spectroscopy
- Electrical and Photoelectrical Transport

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.
