• keithley_test: to scan bias voltage to check if diode is functioning correct and check if OK after handling and installation
• findfocus: as the name says utility to find the focus of the beam using the contact ring of the PD as a knife edge
• findcenter: finds the geometric center of the PD - numbers required as input for scan VI
• 2Dscan: scans the surface after we adjusted the focus of the beam and determined the center of the PD
