CS210-GMX-20-OM
The CS210F-GMX-20-OM is the ARS Ultra Low Vibration Closed Cycle Cryostat for Optical Microscopy applications such as Micro Raman and Micro Photoluminescence.
The CS210F-GMX-20-OM uses a Helium Exchange Gas to decouple the sample from the cold tip of the DE-210 Cryocooler. This prevents almost all vibration from being transmitted to the sample. Sample vibrations of 10 nm have been exhibited. Due to the exchange gas being less conductive, the base temperature will increase by 4-5K and the cooling capacity is roughly cut in half at varying temperatures.
