   ● Industrial design

      Light weight (0.83kg), easy to carry, ready to use, high efficiency 

work, new independent research and development technology is guaranteed

Technical advantages

Advanced laser technology

The blue laser light source is used to improve the scanning accuracy and adaptability. Product details can be clearly captured, and the scanning data fineness has been greatly improved

Industrial design

The scanner is small and easy to carry, and can be operated with one hand; the button design is flexible to control, and there is no need to go back to the computer interface for operation. Can improve the efficiency of work scanning, safe and secure

Photogrammetry function

The system has its own photogrammetry function, which makes the scanning accuracy higher and the technical level is better than that of the same industry

Environmental adaptability

It is not affected by the environment, adapts to various complex application environments, and has good adaptability; it can be used in various environments and three-dimensional applications of different sizes of surfaces
