The Kerr Microscope is a highly advanced and versatile instrument designed for Magnetic Domain Observation and Strong Magnetic Field Testing, leveraging the Magneto-Optical Kerr Effect to deliver precise and detailed imaging of magnetic materials. This state-of-the-art microscope is engineered to operate within a wide Variable Temperature Range of 298 K to 798 K, allowing researchers and engineers to study magnetic phenomena across diverse thermal conditions with exceptional accuracy and reliability.
One of the standout features of the Kerr Microscope is its comprehensive selection of high-quality Objectives, including 5*, 20*, 50*, 100*, a High-temperature Compensated 50* objective, and a Non-magnetic objective. This extensive range of magnifications empowers users to tailor their observations to specific experimental requirements, from broader overviews to intricate, high-resolution examinations of magnetic domains. The high-temperature compensated objective is particularly beneficial for maintaining optical performance under elevated temperature conditions, ensuring consistent image clarity and sharpness.
In addition to its optical capabilities, the Kerr Microscope boasts an exceptional Magnetic Field Resolution facilitated by a PID Closed-loop Feedback Regulation system. This advanced control mechanism achieves an impressive resolution of 0.05 millitesla (MT), enabling precise manipulation and measurement of magnetic fields during experiments. Such fine resolution is critical for detailed investigations of magnetic domain behavior and dynamics, especially when studying subtle changes in magnetization states.
The microscope is also equipped with a powerful Water-cooled Magnet system that provides an In-Plane Magnetic Field with remarkable strength and stability. It can generate magnetic fields up to 3 Tesla at an air gap of 5 millimeters and 2 Tesla at an air gap of 10 millimeters. This capability supports rigorous Strong Magnetic Field Testing, allowing for comprehensive analysis of magnetic materials under conditions that simulate real-world applications and extreme environments.
Temperature Stability is another critical aspect of the Kerr Microscope's design, with precision control maintained at ±50 millikelvin (MK). This stability ensures that temperature fluctuations do not interfere with sensitive measurements or compromise the accuracy of magnetic domain imaging. The combination of temperature control and strong magnetic field generation makes this microscope an indispensable tool for cutting-edge research in magnetism and materials science.
Overall, the Kerr Microscope integrates advanced optical, thermal, and magnetic technologies to enable detailed and reliable exploration of magnetic domains through the Magneto-Optical Kerr Effect. Its broad temperature range, high-resolution magnetic field control, and robust magnetic field generation capabilities make it ideally suited for both fundamental research and applied studies in magnetic materials. Whether investigating domain structures, studying magnetization reversal processes, or conducting strong magnetic field experiments, this microscope provides the precision, versatility, and stability required for groundbreaking discoveries.
