diameters at both planes are essentially equivalent, as
shown in figure 4. Once this position is reached, the
lens is then translated along the beam propagation axis
to measure the beam profile at 256 different planes.

the transparent glass makes it easy to register
fiducial marks on one side of the glass when it
is flipped over for drilling from the second side.
Overall, this testing showed that vias down to
5 µm diameter could…
