Permanent Magnet Kerr Microscope

Product Introduction

Designed for in-depth research on permanent magnet materials, this advanced precision testing instrument enables high-resolution precise measurement and detailed observation of longitudinal, transverse, and vertical magneto-optical Kerr effects under stringent testing conditions of strong magnetic fields, ambient temperature, and high temperature. To ensure sample stability during testing under strong magnetic forces, it features an air-floating displacement stage and specially designed sample fixation devices, making it ideal for studying magnetization and demagnetization processes of permanent magnet materials and advanced micromagnetic technologies.
