Ultra fine multifunctional liquid helium free low-temperature optical thermostat XP series
The company's newly launched crossover premium XP optical thermostat can further reduce the temperature to 1.7K on the basis of the original 3.2K series thermostat. This thermostat combines the advantages of a fully dry thermostat that does not require liquid helium and a lower temperature liquid helium thermostat, inheriting the reliability, flexibility, and practicality of the original thermostat. In addition, the system provides a turnkey solution for users with complex experimental requirements, which will undoubtedly become a milestone in the user experience of thermostats below 2K.

• Maximum compatibility with existing room temperature optical paths, making it easy to achieve direct free path high numerical aperture solutions
Simple and smooth device operation process, one click cooling, precise temperature control
Higher cooling power (>20mW), allowing for more complex experimental setup and thermal loads without sacrificing low temperatures
Introduction to equipment features:
Refrigeration unit:
The system has the characteristics of low cost operation and simple operation. The system adopts a closed-loop refrigeration system with a built-in sealed helium gas, avoiding any consumption of liquid helium
Adopting a variable frequency compressor, it only requires 220V single-phase electricity to operate without water cooling. The working frequency is adjusted in real-time according to system requirements, avoiding additional energy consumption and extending the service life of the cold head
The refrigeration unit has a fully automatic control system, and experimenters can use it without the need for low-temperature experience
Equipment structure:
The sample cavity can be directly placed on any optical platform, with flexible angles, ensuring compatibility with the original experimental plan to a large extent, allowing room temperature experiments to be translated to low-temperature experiments
The integrated design of the host integrates refrigeration, helium, vacuum pump, and system control unit. The structure of the equipment is more reasonable, the degree of automation is higher, and the system's characteristics such as shock absorption have been optimized for high-precision experimental requirements
The isolated optimization design enables independent control of the temperature and vacuum between the sample chamber and the refrigeration system, making sample replacement more convenient
System control:
Touch screen control, all system status parameters and controls can be completed on the system's touch panel, making system control simpler
Software control, complete system control program. The interface supports other third-party control programs. (For example, users can develop programs using Python, MATLAB, LabVIEW, and C)
Sample environment:
The sample chamber can be easily opened for sample replacement and experimental device adjustment
Flexible circuit connection scheme, with over 20 electrical channels available for users to use
Multiple expansion panels to choose from, including RF, fiber optics, special gases, and other mature solutions
Multiple optical windows accept customized design, making optical path design more flexible
The close working distance scheme meets the requirements of high numerical aperture
There are multiple choices of window materials to meet various wavelength requirements
Performance performance:
The all-new generation of helium cycle technology ensures the ultra-high refrigeration efficiency of the system
The three key technologies of heat sink design, trace liquid helium refrigeration sample stage, and double-layer shielding ensure the low-temperature performance of the system
The vibration damping technology isolates the cold head vibration and firmly fixes the sample stage, achieving nanoscale vibration stability
The system intelligently controls the liquefaction of trace amounts of helium while cooling the sample stage, storing excess cold energy and avoiding waste of cold energy
When the experimental heat load is large, the system has a greater ability to compensate for short-term cooling capacity
