This paper continues work reported in an earlier paper on modification of a Cambridge Stereoscan Mk IIA to improve the quality of cathodoluminescent micrographs of biological material. In the work presently described the microscope gun has been offset laterally by 2 mm, to prevent light from the filament passing down through the column to the specimen chamber. The electron beam is brought onto the column axis by deflection coils. This modification effectively eliminates background light in the chamber, and a full parabolic mirror is fitted to maximize light collection. Results for yeasts and wheat seed sections are described.
本文延续了早期一篇论文中所报道的工作，即对剑桥立体扫描Mk IIA型显微镜进行改进，以提高生物材料阴极发光显微照片的质量。在目前所描述的工作中，显微镜的电子枪已横向偏移2毫米，以防止灯丝发出的光穿过镜筒进入样品室。电子束通过偏转线圈被引导到镜筒轴线上。这一改进有效地消除了样品室内的背景光，并安装了一个全抛物面镜以最大限度地收集光线。文中描述了酵母和小麦种子切片的实验结果。
