Note: The 808nm laser belongs to near-infrared light, and the human eye cannot directly see its light spot. If you want to observe it, you can use infrared imaging devices such as infrared thermal imagers and cameras, or use fluorescent materials that can be excited by this wavelength to generate visible light. However, it is strictly prohibited to look directly at the laser to prevent serious damage to the eyes.
