The Kerr Microscope is a highly specialized instrument designed for advanced magnetic field research and material characterization. It offers exceptional precision and stability, making it an indispensable tool for scientists and engineers working in the fields of magnetism and material science. One of the standout features of this microscope is its remarkable temperature stability, maintaining an ultra-fine control within ±50 millikelvin (MK). This precise thermal regulation ensures consistent measurement conditions, which is critical for obtaining reliable and reproducible results during sensitive experiments.
Equipped with both vertical and in-plane magnetic field capabilities, the Kerr Microscope supports a wide range of experimental setups. The vertical magnetic field is generated by a water-cooled magnet capable of producing a strong field intensity of 2 Tesla at an 8.5 mm air gap, and 1.3 Tesla at a 12 mm air gap. This configuration is ideal for strong magnetic field testing, allowing researchers to investigate magnetic phenomena under high field strengths with excellent spatial control. Complementing this, the in-plane magnetic field system also utilizes a water-cooled magnet, delivering up to 3 Tesla at a 5 mm air gap and 2 Tesla at a 10 mm air gap. These robust magnetic field options provide versatility and power, enabling comprehensive studies of magnetic materials under various field orientations and magnitudes.
The optical system of the Kerr Microscope is engineered to deliver superior imaging performance. It features an array of high-quality objectives, including 5*, 20*, 50*, and 100* magnifications. Additionally, there is a high-temperature compensated 50* objective designed to maintain optical clarity and accuracy under elevated temperature conditions, which is particularly beneficial during experiments that involve thermal variations. All objectives are non-magnetic to prevent interference with magnetic field measurements, ensuring that the microscope’s optical performance remains uncompromised by external magnetic influences.
With an optical resolution of 450 nanometers, the Kerr Microscope provides finely detailed images, allowing researchers to observe magnetic domain structures and other micro-scale magnetic properties with exceptional clarity. This high resolution is essential for permanent magnet material characterization, where understanding the subtle magnetic behaviors at the microscopic level is crucial for improving material performance and developing new magnetic technologies.
The Kerr Microscope is specifically tailored for strong magnetic field testing applications. Its robust magnet systems combined with precise temperature control and high-resolution optics make it an ideal platform for investigating magneto-optical effects, domain dynamics, and other magnetic phenomena under stringent experimental conditions. Researchers focusing on permanent magnet materials will find this microscope particularly valuable, as it enables detailed characterization of magnetic properties that directly influence the performance and reliability of permanent magnets used in various industrial and technological applications.
In summary, the Kerr Microscope is a state-of-the-art instrument that seamlessly integrates advanced magnetic field generation, superior temperature stability, and high-resolution optical imaging. Its capability to perform strong magnetic field testing, coupled with specialized features for permanent magnet material characterization, positions it as a critical tool for cutting-edge research in magnetism. Whether for academic research or industrial development, this microscope offers unparalleled functionality and precision to explore and understand magnetic materials at a fundamental level.
