无像差显微镜光学组件的互动优化

光学显微镜旨在放大肉眼不可见的物体。为此需要采用高品质光学器件来获得优秀的分辨率。但是,所有光学组件都会对光路中的光线带来负面的影响,最终导致像差。本文将重点介绍此过程中涉及的光学元件及其物理参数。在此基础上,本文对减少像差的方法原理进行了一次历史概述。结果表明,将显微镜看作一个整体系统有助于协调其各个组件并获得最佳微观结果。

无限远光学系统

“无限远光学”这一概念是指在显微镜的物镜和镜筒透镜之间具有平行光线的光束路径。平面光学元件可以进入到这个“无限远空间”中,而不影响成像,这对于利用DIC或荧光等对比度方法至关重要。 现代显微技术需要在无限远光路中添加多种光学仪器,如光源或激光装置。满足这一需求的不同方法已经出现,本文对其进行了描述。

光学显微镜简史

显微镜的历史始于中世纪。早在11世纪,阿拉伯世界就使用抛光绿柱石制成的平凸透镜作为阅读石来放大手稿。然而,将这些透镜发展成显微镜并非某一个人的功劳,而是众多科学家和学者共同努力的结果。
