Beamage-3.0 User Manual Revision 6.0 29
4.5.4.1. Divergence
Figure 4-34 Divergence Button
The “Divergence” button activates a new tab on the right-hand side of the user interface. It contains all the
settings and results relative to the beam divergence (refer to section 0). To compute the divergence and
abide by the ISO-11146-1:2005 standard, the first step is to place an aberration-free lens between the
Beamage-3.0 and the laser. The lens should be placed in the far-field of the laser beam while the
Beamage-3.0 should be at the focal point of the lens. The second step is to enter the focal length of the
lens in the software. Since the focal length is wavelength dependent, make sure to use the correct value
for your laser in the settings. The divergence in both main axes (x and y) are computed as defined by the
ISO-11146-1:2005 and ISO-11146-2:2005 standards and displayed at the bottom of
the “Divergence” tab.
Warning
The Beamage-3.0 sensor must be placed precisely at the focal point, not
at the beam waist.
4.5.4.2. Relative Position
Figure 4-35 Relative Position Panel
The “Relative Position” panel activates a new tab on the right-hand side of the user interface. It contains
all the settings and results relative to the origin position and the camera lens calibration. This tool allows
you to easily align a laser to any desired position. Please refer to section 0 for more information about this
functionality.
4.5.4.3. Camera Lens Calibration
Figure 4-36 Camera Lens Calibration Panel
The “Camera Lens Calibration” panel activates a new tab on the right-hand side of the user interface. It
contains the procedure relative to the camera lens calibration. This tool allows you to easily calibrate a
system that contains a magnifying lens. Please refer to section 0 for more information about this function.
