Abstract:
1. An apparatus for manufacturing carbon nanotubes comprising: an observation device comprising an observation tube, an observation window arranged on the top of the observation tube, a first half-reflecting, pellicle mirror installed with an angle 45° in the observation tube, and a second half-reflecting, pellicle mirror installed parallel to the first half-reflecting, pellicle mirror; a work stage disposed under and separated a certain distance from the observation tube; a laser device arranged perpendicular to the observation device and optically directed at the first half-reflecting, pellicle mirror; a lighting device arranged perpendicular to the observation device and optically directed at the second half-reflecting, pellicle mirror; and a substrate coated with a catalyst layer and located on the work stage, wherein the catalyst layer is configured to grow carbon nanotubes by heating the substrate locally and the observation device is configured to observe the carbon nanotubes during the growth process.
