Micro-PL Cryostat: CS204-DMX-20-OM

The CS204-DMX-20-OM is our ultra low vibration closed cycle cryostat for optical microscopy applications, such as micro-photoluminescence (Micro-PL).
The DMX-20 interface opens up a wide range of capabilities never before possible with a closed cycle cryocooler. The Micro-PL cryostat uses a helium exchange gas to decouple the sample space from the cold tip of the DE-204 cryocooler. This prevents almost all vibration from being transmitted to the sample space. Scientists have demonstrated vibration levels as low as 3-5 nm with our Micro-PL cryostat.
Because the exchange gas is inherently less efficient than cooling by conduction, the base temperature of the sample will be 1-2 K higher than the cryocooler. Additionally the DMX-20 interface requires a downward orientation of the cold tip to facilitate convective cooling of the exchange gas.
