Currently, mainstream 3D foot laser scanners are not harmful to the human body.
Reasons are as follows:
Use of safe lasers: Typically employs low-power visible light or near-infrared lasers, whose energy levels belong to safety classes (Class 1 or Class 2), far below the threshold that could cause harmful effects on human tissues (including eyes and skin).
Their safety standards comply with IEC 60825.
Non-ionizing radiation: The light emitted during scanning is non-ionizing radiation, fundamentally different from ionizing radiation such as CT or X-rays.
It does not have the ability to alter cell DNA or cause radiation damage. Its principle is similar to the infrared light emitted by a remote control for an old Nokia phone, except that the light is precisely modulated and scanned when transmitted.
Very short duration: A single foot scan takes only a few seconds to十几 seconds (a dozen seconds), so the exposure time of the human body to the laser is extremely short; there is essentially no radiation concern.
Widespread application and safety: 3D laser scanning technology has been applied in medical fields (such as plastic surgery, prosthetic customization), industry, cultural heritage preservation, and other areas for decades. Its safety has been verified through long-term practical use and scientific validation.
Precautions: Several points to note when using.
Do not stare directly at the laser beam: Although it is not powerful, as a precaution, avoid staring directly at the working laser beam for extended periods, especially with devices that have higher scanning power.
However, the laser of a foot scanner is generally within the scanning area and positioned relatively low, making direct viewing unlikely.
Purchase or use: When purchasing or using, please choose products from manufacturers that have passed certifications such as CE and FDA.
You can confidently use a 3D foot laser scanner because it utilizes safe optical technology. Its working principle is like taking a very fine-grained photograph of your foot—it will not produce any adverse reaction in the human body.
