B. Graphene Nanomanipulation System
The platform setup is composed of an inverted Olympus IX71 microscope (Fig. 2), with a 25x OCTAX objective and a high speed Dalsa Genie CMOS camera (1”, 1400 x 1024 pixels,60fps). An infrared (IR) laser (CW 1480nm, max power of 120 mW) from OCTAX Microscience GmbH is connected to the rear port of the microscope. The focused laser spot diameter is approximately 1µm.
