zz[illumination regime: pw = plane wave; so = superoscillatory]-yyy[image number in time sequence, from 000 to 300]-xxxxx[applied bias in multiples of 0.1mV]

e.g. pw-000-16030.tif => plane wave illumination, 1st image recorded (in the plane wave illumination dataset), applied bias of 16030*0.1 mV = 1.603 (V)
