USEOFTHELIGHTMICROSCOPE
USE OF THE LIGHT MICROSCOPEEach time the microscope is to be used it should be set up correctly to give a good image. Most often users forget to adjust the iris diaphragm and focus the condenser to give its optimum performance, this could result in objects in the preparation being undetected.There are many microscope set up procedures for specific functionality but the most versatile for general use is ‘Critical Illu......阅读全文

Transmission－Electron－Microscope－(TEM)
所谓TEM，就是一个放大镜叠加了一台照相机。这台放大镜的放大倍数比较高，可高达一百万倍。当然，抛开分辨率谈放大倍数都是耍流氓，那么，TEM的分辨率有多高呢？答案是 it depends。一般来说，TEM的分辨率要在1到2个纳米，STEM更高，但是STEM得成像技术类似于SEM，但用的不是二次电子。我

一、偏光显微镜的特点偏光显微是鉴定物质细微结构光学性质的一种显微镜。凡具有双折射性的物质，在偏光显微镜下就能分辨的清楚，当然这些物质也可用染色法来进行观察，但有些则不可能，而必须利用偏光显微镜。偏光显微镜的特点，就是将普通光改变为偏振光进行镜检的方法，以鉴别某一物质是单折射性（各向同性）或双折射性（
