T120#1
Installed the 30mm diameter , 120mm thickness sample (1623048-4) called 120#1
I moved z_IU to 18.51mm
pink tape is at bottom towards IU
the sample is held roughly t its central thickness position to limit its tilt that could misaligned the beam on the sensors.
in that configuration, the DC is still varying between about 2 to 5V while changing z from 20 to 120mm...
Pt = 27.0mW ; Pin = 31.3mW
Pt = 4.72W
long z scan at x,y centers : Fri, Apr 5, 2024 11-52-43 AM.txt
z edges seem to be at 39 and 90 mm. z_center = 64.5mm
The DC is still slowly decreasing with increasing z from aboiut 5 to 3 V... depending on measurements results I might aligned DC to specific z.
