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…

当心“无效”放大率
在一个最简化的情况，光学显微镜由一个靠近标本的透镜（物镜）和一个靠近眼睛的透镜（目镜）组成。显微镜放大率是两个显微镜透镜系数的乘积。比如，40倍物镜和10倍目镜可以得到400倍放大率。

偏振光显微观察
偏光显微镜通常应用于材料科学和地质学领域，根据矿物的折射特性和颜色来识别矿物。在生物学中，偏光显微镜通常用于晶体等双折射结构的识别或成像，或用于植物细胞壁中纤维素和淀粉粒的成像。
