传统的光学显微镜是以光学透镜为主体,利用透镜能将物体放大成像的功能而制成的。一般地,单级透镜能将物体放大几十倍,级联使用可达到千倍以上。制造放大倍数更大,分辨率更高的显微镜系统将遇到许多不可逾越的技术上的困难。从根本上说,光的衍射效应限制了光学显微镜进一步提高分辨率的可能性。根据瑞利判据,光学成像系统 Traditional optical microscope is based on the optical lens as the main body, the use of the lens to enlarge the imaging function of the object made. In general, a single lens can magnify the object tens of times, the use of cascade can reach more than a thousand times. Making microscope systems with greater magnification and higher resolution will encounter many insurmountable technical difficulties. Basically, the diffraction effect of light limits the possibility of optical microscopy to further increase resolution. According to Rayleigh criterion, optical imaging system
