reached the end of the actuator after 4h, so the mode jumped and the measurement didn't fully finish, but still very interesting. One can see the bunch of bond pads for the bond wires around the 3mm EG&G PD with a resolution of 10um (left picture). It's not that nice with 25um resolution i did before (picture on the right). One can also see the shadow of the bond wires on the left. Started a new measurement over night (15um resolution)
