Optics Education Kit
The EWSZ-1 optics experiment kit is developed for general physics education in universities and colleges. This kit provides complete set of optical and mechanical components (including light sources), which can be conveniently assembled to construct experimental setups. Almost all optics experiments required in general physics education (e.g. geometrical, physical, and modern optics) can be constructed in sequence using these components. Through selecting and assembling individual components into whole setups by students themselves, their experimental skills and problem solving ability can be greatly enhanced. The effectiveness of teaching and learning will be much better than those of using completing equipments. As examples, the following experiments can be setup. It is evident that much more experiments may be figured out using this kit.
