Why are the telescopes in the regular shopping mall counters often expensive? On the one hand, the telescope is a kind of unpopular product. The number of shops sold is very small, so the cost is high in all aspects. On the other hand, it is also because of a good telescope. Its own details are all complex and sophisticated. technology.
Here's a brief introduction to what you might be interested in about the material, parts, and internal construction of the telescope:
First of all, it is the smelting of Optical Spherical Lens. Because optical glass has very high requirements on optical constants and other technical specifications, it has special requirements on production technology and high technical barriers. Until today, only Germany, China, Japan, and the United States in the world. A few manufacturers in a few countries, such as the United Kingdom, have mastered their formulations and melting technologies, which are technical and capital-intensive, and are also important war preparations.
Optical glass differs from ordinary glass in raw materials. In addition to extremely high-purity raw materials, there are a large amount of heavy metal oxides (such as lead and antimony) and rare earth elements. In order to maintain purity, special platinum crucibles are used in the smelting. Platinum is used to prevent the ruthenium atoms from melting into the glass during smelting. Ordinary glass in life, which is slightly green when viewed carefully, is the common iron shovel used when smelting ordinary glass. Iron ions are green in the glass. These details need to be considered for the rigorous quality optical glass smelting.
