Until the end of Ming and early Qing Dynasty, only after some scientific and technological talents inspired by western scientific thought gradually popularized the applicability of lens and lens. In short, in the Ming Dynasty, with the continuous research of some Chinese scientists and the improvement of mirror making technology, magnifying glass and glasses are no longer rare, which has been very common among some scholars and businessmen.

But these are inseparable from the Chinese scientists who were good at studying at that time, but they were not paid attention to by the mainstream "Western things". Chen Feng in the corner of the history restricted the development of China in the field of Optical Science and technology, so that before 1949, China could not make optical glass with certain scientific and technological content. Therefore, without these Chinese scientists who have been exploring optics from the late Ming Dynasty to the early Qing Dynasty, the most common objects, such as glasses, hand-held telescopes and camera lenses, are still more luxurious consumer goods. It is just like the fact that the LCD panel has been blocked by foreign technology for many years, and the reason why the extension products are extremely high is the same.

Next, let's share with you the historical deeds that have made a profound contribution to the Chinese optical industry, but are sleeping in the corner of history.

Jue - the first person to use telescope in military affairs

Born in the thirty-six years of the Ming Wanli, about 1608, the word zijue, Changzhou (now Wu County, Suzhou City) was born. In the last years of Ming Dynasty, mechanical manufacturers made celestial instruments and telescopes; some data showed that they were the first to use them in military fields.

The main activities were from the first year of Chongzhen to the 14th year of Chongzhen (ad16828-1641). In the early years, as Jiashan County supplementary students to Zhejiang Province for examination, they joined Hangzhou reading society, which is mainly about reading more and more important in the examination. In the eighth year of Chongzhen (ad1635) in the Ming Dynasty, Zhang Guowei, the then Anhui governor of the CPC, hired zhangguowei to make the combined equipment of copper gun and thousand mirror in the military camp for the battle of zhangxianzhong Department of Anqing. In the war, Zhang Guowei recommended the military to the court by adding the thousand li mirror to the copper gun to improve the hit rate, but it was not reused; later, he built the water vehicle and fire Weapons such as spears, mines, crossbows, etc.

In the 17th year of Chongzhen in Ming Dynasty (ad1644), after the Ming Dynasty was destroyed and the Qing army entered the customs and officially established the Qing Dynasty, they decided not to take the official career, but to live in the mountains of Jiaxing generation. Only daughters were buried with the help of friends after their death, and finally died of poverty.

He has written the works of "the false discrimination of the heaven inclining to the northwest", "the theory of huntianyi map", "the colorless identification of celestial bodies", "the discrimination between the north and the south of the sky shape", "the theory of the guard of the mind by the reflection of the confusion" and "the theory of earth survey of the objects".
