The Magneto Optical Cryostat is a state-of-the-art instrument designed for advanced research applications requiring precise temperature control, strong magnetic fields, and excellent optical access. This sophisticated cryostat is ideally suited for experiments in Raman spectroscopy, particularly those involving quantum materials, where maintaining stable and controllable low temperatures alongside high magnetic fields is essential for accurate measurements and analysis.
One of the standout features of the Magneto Optical Cryostat is its exceptional optical viewing angles. It offers a top window with a full 70° viewing angle, enabling researchers to observe samples with minimal obstruction and maximum clarity. Additionally, side windows provide a 13° full viewing angle, allowing for versatile optical configurations and enhanced experimental flexibility. These optical access points are crucial for Raman spectroscopy cryostat applications, where precise laser alignment and effective collection of scattered light are necessary for high-quality spectral data.
The sample space of the cryostat is spacious and thoughtfully designed, measuring 89 mm in diameter and 88 mm in height. This ample volume accommodates a variety of sample sizes and experimental setups, making it highly adaptable to diverse research needs. Whether investigating thin films, bulk crystals, or complex quantum materials, users can position their samples securely within this optimized environment.
Magnetic control is a critical aspect of this cryostat, which features a conical split-coil superconducting magnet oriented in the vertical direction. This magnet generates a magnetic field strength of ±1 Tesla with an impressive uniformity of ±0.3% over a 3 cm spherical area. Such uniformity ensures consistent magnetic conditions throughout the sample volume, which is vital for experiments that are sensitive to magnetic field variations. Furthermore, the system supports a field variation speed of 0.7 Tesla within 30 minutes, allowing for rapid adjustments during experimental runs and enabling dynamic studies of magnetic effects on quantum materials.
Electrical connectivity is another key advantage of the Magneto Optical Cryostat. It supports up to 80 cables in total, including 16 DC lines and 4 high-frequency RF lines rated up to 20 GHz. This extensive electrical channel capacity facilitates complex experimental configurations involving multiple sensors, actuators, and microwave components. The integration of high-frequency RF lines is especially beneficial for advanced spectroscopy techniques and quantum device characterization, where fast signal transmission and minimal noise are paramount.
The temperature range of the cryostat spans from an ultra-low 1.7 K up to 350 K, covering a broad spectrum of experimental conditions. This wide range enables researchers to explore various physical phenomena, from superconductivity and magnetism in quantum materials at cryogenic temperatures to room temperature studies. Additionally, the system incorporates Fast Cooldown technology, significantly reducing the time required to reach base temperature. This feature enhances laboratory efficiency by minimizing downtime between experiments and enabling quicker turnaround for sequential measurements.
In summary, the Magneto Optical Cryostat offers a comprehensive solution for researchers working with quantum materials and Raman spectroscopy. Its excellent optical access, robust magnetic field capabilities, extensive electrical connectivity, and versatile temperature control make it an indispensable tool in modern condensed matter physics and material science laboratories. Whether the goal is to study fundamental properties or develop cutting-edge technologies, this cryostat provides the precision and reliability needed to advance scientific discovery.
