Is the laser technology used in 3D foot scanners harmful to the human body?

3DOE's 3D foot scanner mainly uses laser technology to scan and measure the human foot, obtain 3D foot data, and generate corresponding measurement reports.

Many people worry whether laser scanning is harmful to the human body.

In fact, this concern is unnecessary; under normal use, it will not harm human health, and children, the elderly, and pregnant women can all be measured.

Currently, most 3D foot scanners on the market belong to Class 1 or Class 2 / 2M low-power line lasers, with extremely low power far below 1mW, which is actually at the same safety level as ordinary laser pointers.

If it is Class 1, it is the highest safety level, and even long-term direct viewing will not damage the eyes.

If it is Class 2 / 2M, the human blink reflex (about 0.25 seconds) can protect the eyes, and an accidental brief scan to the eyes is harmless. As long as we do not deliberately stare at the beam continuously, it will basically have no impact on us; daily scanning will not harm the human body.

Moreover, these types of lasers belong to visible light, have no ionizing radiation, and will not penetrate the skin like X-rays.

Laser scanning measurement of the foot leaves no radiation residue and causes no harm to the human body or eyes.

Of course, it is not recommended to stare at the beam continuously; following normal operation is completely fine.

The principle of laser scanning is very simple: projecting a thin laser line to scan across the foot surface, a camera captures the deformation of the laser line on the foot, and software calculates the 3D contour; the laser is a thin, defocused line rather than a focused high-energy spot, so the energy is dispersed.

However, when purchasing equipment, we should also look for well-known brands and check the qualification certificate and laser safety labels.

If you buy equipment from unknown brands, the use of low-quality components may lead to potential risks during use.

3DOE's laser 3D foot scanner offers high safety and causes no harm to the human body or eyes during measurement; it also has strong ambient light resistance, so it will not be interfered with even near bright windows or under ordinary indoor lighting, maintaining good stability in complex lighting scenarios such as clinics and stores, and it does not require frequent calibration.

Calibrate once, and it can be used continuously without recalibration; it also offers high precision within 0.5mm, making it especially suitable for foot health assessment as well as the design and production of corrective insoles.
