The third exhibition hall named "OPTICS OF CHINA" covers an area of 488 square meters and the main color of the environment is golden, symbolizing a harvest scenery of China and the magnificence of the country. Represented by the independent study optical results, the exhibition show the marvelous achievements in optical development since the founding of the new China.
1. 光学探路者
Optical pathfinder
亦称“院士墙”，展示我国光学领域的两院院士，他们为我国光学事业发展做出了杰出贡献，使我国傲然屹立于世界光学领域的前沿。
Optical pathfinder is also name as “academician wall” which show the name list of academicians of the Chinese academy of sciences and the Chinese academy of engineering in optical field. They make outstanding contributions to the development of optical career and make China in the world lie in the leading edge in optical field.
2. 红宝石激光器
Ruby laser
展示我国第一台红宝石激光器，它诞生时间仅比世界上第一台激光器迟不到一年，引起了国内外学术界震惊，开创了我国激光领域的先河。
It shows the first ruby laser in China, this new device was accomplished after the first laser in the world with margin of less than a year. It shocked the world and it also made a new era of Chinese laser science.
3. 光学起步
The start of optics
建国初期自主研发的高温金相显微镜、高精度经纬仪、万能工具显微镜、晶体谱仪、大型摄谱仪、多臂投影仪、光电测距仪、电子显微镜、第一炉光学玻璃，史称“八大件一个汤”。The high temperature metallurgical microscope, High precision theodolite, universal tool microscope, crystal spectrometer, large spectrograph, dobby projector, geodimeter, electron microscope and the first optical glass furnace developed independently in the early years of the new China are called “ the big eight elements and one bowel of soup ”.

4. 神光激光装置
Shenguang laser device
模型展示的神光激光装置是目前国内规模最大，国际上为数不多的高性能、高功率激光核聚变装置，是我国在激光惯性约束聚变领域的重大科研成就。
Shenguang laser device model displayed in the exhibition has the largest in scale nationwide. It is one of the several laser fusion device with high performance and high power in the world and it indicates a great scientific research achievement of China in the field of laser inertial confinement fusion.
5. 上海光源
Shanghai light source
微缩模型展示的上海光源是光学领域标志性项目，可同时提供从远红外线到硬X射线等不同波长的不同强度光束，容纳数百个不同领域的实验站进行研究和试验。
Shanghai light source displayed in the miniature scale is the marking project in optical field and it can provide lights at different wavelengths and intensity from far infrared ray to hard X-ray at the same the time and accommodate hundreds of experimental station from different filed to undertake researches and trials.
