For the two-channel imaging, the microscope, objective and laser were the same as stated before. The images were captured with a VIS camera (PCO edge 4.2 bi, Kelheim, Germany) and a XEVA (Xenics, Leuven Belgium) NIR optimized InGaAs camera. And a dichroic mirror (AHF analysentechnik AG, HC R1064) was inserted to split the signal into two cameras. In this case, the VIS camera only captured the signal below 1064 nm corresponding to the E11 wavelength range, while the E11 * intensity was observed with the NIR camera, so the E11 and E11 * signal SWCNT could be seen at the same time.
