光学仪器是由单个或多个光学器件组合构成。是能够产生光波并显示图像，或接收光波并分析、确定其若光性质的一类仪器。光学仪器是仪器仪表行业中非常重要的组成类别，是工农业生产、资源勘探、空间探索、科学实验、国防建设以及社会生活各个领域不可缺少的观察、测试、分析、控制、记录和传递的工具。特别是现代光学仪器的功能已成为人脑神经功能的延伸和拓展。

     An optical instrument is a combination of single or multiple optical devices. It is a type of instrument that can generate light waves and display images, or receive light waves and analyze and determine their photogenic properties. Optical instrument is a very important component category in the instrumentation industry, and is an indispensable tool for observation, testing, analysis, control, recording and transmission in various fields of industrial and agricultural production, resource exploration, space exploration, scientific experiments, national defense construction and social life. In particular, the function of modern optical instruments has become an extension and expansion of the function of human brain nerves.
