I tested the new design with the 75 mm and 25 mm cylinder lens.  The spot size is around 24 micrometers  and circular. The line thickness is 63 micrometers. This can be seen from the picture. The pixel size is 4.8 micron. The line is around 13 pixels wide. The cross scan error is in the order of 40 micrometers. This is an enormous improvement as compared to the first version; which had a line thickness of 260 micrometers.

The setup is shown below;
