A Guide to Using Microscopy for Drosophila (Fruit Fly) Research

The fruit fly, typically Drosophila melanogaster, has been used as a model organism for over a century. One reason is that many disease-related genes are shared between Drosophila and humans. It is…

如何形成清晰的图像

在显微镜检查中，景深常被看做经验参数。在实际操作中，会根据数值孔径、分辨率和放大率之间的相关性确定该参数。为了获得最佳视觉效果，现代显微镜的调节设备在景深和分辨率之间实现了最佳平衡，这两个参数在理论上呈负相关。
