3D Calibration
Previous pageReturn to chapter overviewNext page

This chapter explains how to calibrate a 3D optic system. There are two different possibilities depending on your scan head:

 

Z Lookup Table (2D scan head with a moveable z-axis):

Using lookup control points in SAMLight. The process consists of an iteration of measurements, of the read out of the marking result and of the calculation of new software settings using the measured values. The most important and time consuming part is the calibration of the Z lookup table (mapping between 'Focus distance [mm]' and 'Z - value [bit]' of the Z shifting device).

F-Theta Factor (3D scan head with F-Theta lens)
