A simple illumination system is described that can be easily adapted to a laboratory stereomicroscope allowing for low power high contrast dark field surveying. The system uses commercially available fibre optic lamps, standard bright field objectives and produces a large, evenly illuminated field suitable for photography.
本文描述了一种简单的照明系统，该系统可轻松适配于实验室体视显微镜，实现低倍高对比度暗视野观察。该系统使用市售光纤灯和标准明场物镜，可产生适合拍照的大尺寸均匀照明视场。
