The Low vibration Micro-Raman cooler is easy to use, light weight, cryogen free cryostat capable of ~ 8K to 450K temperatures at the sample.

FEATURES

• Sample vibration less than 5 nanometers

• Continuously variable sample to window distance

• Sample temperature 8K to 450K with 4K Displex DE-204S cryocooler 

• 1 High Purity Quartz Window installed (optional 2nd window for transmission)

• Window materials for optical spectroscopy (Vis, UV, IR  windows available)

APPLICATIONS

Customer testimonial

This is to inform you about our recent tests on the closed-cycle cryostat designed for Raman and infrared experiments under the microscope.
 
Here you can find two photos taken, one at room temperature with the system off, and the second one at 8K and their relative Raman spectra. As you can see from the pictures, no vibration can be detected and the Raman spectra are pretty nice.  This sample was also interesting because it displays a phase transition on cooling down: Raman spectra at different temperatures clearly show the onset of this phase transition.

In conclusion we are really satisfied.
