What are the domestic and international EMC (electromagnetic compatibility) standards for biological microscope imaging systems?

Biological microscopy imaging systems (e.g., digital slide scanners, fluorescence microscopy imaging systems) must comply with GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international) EMC standards. These systems include a high-precision electric stage, an autofocus system, a camera (CMOS/CCD), and a light source (LED, mercury lamp). The standards require that sub-micron level movement and imaging stability be unaffected by the system's own motor drive, camera readout circuitry, and environmental electromagnetic noise, ensuring clear images, no streak noise, and accurate positioning—crucial for pathological diagnosis and scientific research.
