Skin analyzers (e.g., VISIA, used to analyze skin texture, pigmentation, blood vessels, etc.) must meet GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international) EMC standards. They employ multispectral imaging (white light, ultraviolet light, polarized light, etc.) and image analysis technology. The standards require stable driving of different light sources (LED or fluorescent lamps), and that CCD/CMOS camera imaging be unaffected by power supply noise and drive circuit interference, ensuring clear and accurate skin images for reliable data in subsequent analysis.
