光学显微镜的分辨率因透镜制造技术提升而显著提高。

显微镜是一种用于放大微小物体或观察微观结构的光学或电子仪器,通过将光线或电子束聚焦,使肉眼无法直接看到的细节清晰可见。它在科学、医学、工业等领域具有不可替代的作用,以下是显微镜的详细介绍:一、显微镜的历史发展早期尝试16世纪末,荷兰眼镜制造商汉斯·詹森(Hans Janssen)和其子扎卡里亚斯(Zacharias Janssen)被认为发明了最早的复合显微镜(由多个透镜组成)。17世纪,罗伯特·胡克(Robert Hooke)用显微镜观察软木细胞,首次提出“细胞”概念;安东尼·范·列文虎克(Antonie van Leeuwenhoek)改进显微镜,观察到微生物,被誉为“微生物学之父”。现代显微镜的突破19世纪,光学显微镜的分辨率因透镜制造技术提升而显著提高。20世纪30年代,电子显微镜(如透射电镜TEM、扫描电镜SEM)问世,突破了光学衍射极限,分辨率达纳米级。21世纪,超分辨显微镜(如STED、PALM/STORM)获得诺贝尔奖,实现光学显微镜的纳米级成像。...
