Photonfocus 3D triangulation cameras - linchpin for maximum precision and speed

The principle of 3D laser triangulation
In 3D laser triangulation, the synergy between camera and laser is key to capture precise 3D measurements. In this technique the laser emits a beam onto the object, and the camera records how the laser light reflects off the surface. By analyzing this reflection, the system calculates distances and angles, enabling the creation of an accurate 3D profile of the object.

Photonfocus' 3D laser triangulation cameras play a central role in this process, serving as the linchpin for maximum precision and speed. In a wide range of applications where precise 3D measurements are required, Photonfocus cameras are the critical component that unlocks the full potential of 3D laser triangulation technology. Crucial to their efficiency is also the selection of the right camera based on professional advice from our camera experts.
