Optical cryostat with cryogenic head type CH-204-M
The device is equipped with an adapter for mounting the high-pressure chamber into the cryostat and an adapter with a clamping element for connecting the high-pressure chamber to the cold finger. The high-pressure chamber has a cylindrical shape with an additional clamping ring. It is possible to connect a gas pass to enable the operation of the membrane mechanism without raising the temperature of the cryostat.
The most significant device features:
- Can be adapted to be connected to a high-pressure chamber
- Temperature range: from below 10 K to 500 K
- Cooling in a closed circuit using the CH-204-M cryogenic head
- Cryostat equipped with vacuum connections enabling the configuration of electrical feedthroughs as desired
- Adapted to measurements using an optical microscope
