Description

technical field [0001] The invention relates to the mechanical structure of an ultra-high resolution fluorescence imaging sample stage, in particular to a mechanical adjustment system of a copper-based graphene stage for carrying fluorescent samples. Background technique [0002] Ultra-high resolution fluorescence imaging is an important aspect within the imaging field. It can be used for ultra-high resolution imaging of fluorescently labeled biological samples such as DNA. At present, the main ultra-high resolution technologies include: photoactivated localization microscopy (PALM), stochastic optical reconstruction microscopy (STORM), and stimulated emission depletion (STED). These microscopy techniques use multiple imaging, positioning and computer digital image processing techniques, or use two different laser beams and helical phase modulation techniques to achieve compression of scanning light sources. [0003] When the surface of noble metal is irradiated by inciden...
