…applications. A telescope adapts the beam diameter for the scanhead. Positon sensitive 4Q-diodes help alignment control of the laser beam into the scanhead. Inside the scanhead, light passes a variable three-lens telescope that is used to adapt the beam diameter to the objective lens entrance…

Beam Diameter (Radius, Width) The beam diameter (generally defined as twice the beam radius, no matter what the particular definition of the beam radius is) is the most important propagation-related attribute of a laser beam. In case of a perfect top-hat (or flat-top) profile the beam diameter is…

…as the beam quality becomes higher, the beam brightness increases. The measurement and adjustment of the beam diameter does not affect the total power being delivered by a laser beam, but does effect how the total power is concentrated. Controlling the power density or brightness of a laser beam

beams of a few microns in diameter to be measured with a resolution down to 0.1µm. And because, at some point in the scan the full beam strikes the detector, accurate power and noise measurement can be taken. Like the slit scanner, the accuracy of a scan depends upon the geometry of the beam. For…
