The history of the development of image measuring instruments

The image measuring instrument is a very important component category in the instrument industry. It is used in industrial and agricultural production, resource exploration, space exploration, and scientific practice. It is an indispensable tool for observation, testing, analysis, control, recording and transmission in various inspection fields, national defense and social life. In particular, the function of modern optical instruments has become an extension and expansion of the function of the human brain.

In recent years, the market scale of the domestic optical instrument manufacturing industry has also shown a trend of rapid expansion. As of the end of 2010, there were 395 enterprises above designated size in my country's optical instrument manufacturing industry. In 2010, the cumulative output of optical instruments nationwide was 30,085,300, a year-on-year increase of 25.45% and a year-on-year increase of 35.99%; the entire industry achieved sales revenue of 53.167 billion yuan, a year-on-year increase of 19.26.

In my country's optical instrument market, the entry and success of multinational companies has become an indisputable fact. Enter Chinese market. Although some domestic companies have gradually emerged and occupy relatively high positions in the optical instrument manufacturing market, many companies have poor capabilities. Compared with similar foreign products, high-end products are still at a technological disadvantage. After a long period of development, image measuring instruments have formed illuminance meters, melting point meters, eyepieces, objective lenses, ultraviolet radiation meters, theodolites and level meters, color difference meters, cameras, refractometers, magnifiers, microscopes, telescopes, prisms, lenses, filters , Color filter, laser level meter, laser rangefinder waiting for several subcategories.
