The DE204*F-DMX-20-OM is our Ultra Low Vibration Closed Cycle Cryostat for Optical Micrscopy applications such as MicroRaman and Micro Photoluminescence. The DE204*F-DMX-20-OM uses a Helium Exchange Gas to decouple the sample from the cold tip of the DE204 Cryocooler. This pre-vents almost all vibration from being transmitted to the sample. Sample vibrations of 3-5 nm have been demonstrated by users. 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.
