几何光学是以光线为基础，研究光的传播和成像规律的一个重要的学科。在中学物理中，几何光学是很重要的一部分内容，它主要包括的内容有：
Geometric optical light is based on the spread of optical imaging and one of the important subjects. In Physics, geometrical optics is a very important part, it mainly includes the contents:

光的反射、折射定律，折射成像，透镜成像，光的干涉、衍射等等。为了更好的演示几何关学实验的，GY—II激光光学演示仪被研制出来了。它结构简单，使用方便，功能多，调节灵活，装卸方便，且光路清晰。既可以展开综合性实验，能把具有灵活性、综合性、研究性、设计性的内容演示出来，学生也可以自己灵活的组合装配调试实验，有助于培养学生的创造思维和动手能力，补充了中学物理几何光学的教学需求。
Light reflection, refraction law of refraction imaging, imaging lenses, optical interference, diffraction, and so on. For a better presentation of the Commissioner of the geometry, GY-II laser optical Demonstrator has been developed. It is simple, easy to use, more functional, flexible regulation, to facilitate loading and unloading, and optical clarity. Can start a comprehensive test can be flexible, comprehensive, research, design and demonstration of the contents out, students can also assemble their own flexible adjustment
