Located in the western border of China, Xinjiang is the largest provincial administrative region in China with an area of ​​1.66 million square kilometers and a population of 2.18 million. The administrative district is divided into two prefecture-level cities: Urumqi and Karamay. Seven regions: Hami, Turpan, Aksu, Kashgar, Hotan, Tacheng, and Altay. The areas where granite has been developed are mainly Shanshan County in Turpan, Yiwu County in Hami Prefecture, Qitai County in Changji Hui Autonomous Prefecture, Toli County in Tacheng District, and Qinghe County in Bole Tala Mongolian Autonomous Prefecture. At present, the more mature granite varieties include Karamaijin, Yanshanhong, Xinjiang Black Gold Sand, Xinjiang Gold Diamond, Xinjiang Coffee Diamond, Xinjiang Snow Lotus. Other common varieties are: brown diamond, gold diamond, Xinjiang yellow, Tianshan sapphire (the characteristics are similar to Dunhuang Mo Yuhuang, but Mo Yuhuang crystal speckle is orange yellow, closer to the exterior color of the building exterior), Ma Lanhong ,åœé‡Œçº¢, Xinjiang gray hemp, Tianshan white hemp, Tianshan blue G6501 Hami star blue G6502 Hami sesame green G6503 Tianshan ice flower G6504 Tianshan green G6507 Shuangjing red G6508 Shuangjing flower G6513 Tianshan red G6520 Xinjiang red G6521 Tory chrysanthemum yellow G6522 Snowflake Green G6523 Tori Red G6524 and Shuohong G6530 Tianshan Hongmei G6531 Yan Shanhong and so on. The yield of famous stone in Xinjiang is generally low. The bright colors of granite are attributed to the fact that the rock contains various metal elements. The metal elements produce beautiful colors under the action of oxidation. For example, the common pure iron is grayish white, and the iron oxide fe2o3 is rust red. Pure copper is copper yellow color, and copper oxide is mostly green, brown, and the like. Therefore, rich color granite is often associated with metal ore and has sufficient oxidation, that is to say, there are a large number of crack structures to facilitate the entry of moisture and oxygen. Therefore, the yields of gold and hemp in Kalamaili, Xinjiang and Hubei are generally low. The famous Tianshan Red Stone is just a historical memory. High transportation costs and a relaxed policy environment are tangled. Seventy percent of the country's stone consumption is concentrated in the southeastern coastal areas, but the mines in the southeast and central areas will be shut down in recent years. The stone development environment in Xinjiang is relatively loose, but the transportation cost of Xinjiang's stone to Fujian water head is on average. 60 yuan per square meter. In the future, whether Xinjiang's stone can play a mainstream role in the market will take time to verify. Photolithographic Multispectral Filter
Photolithographic multispectral filters are precisely produced by a composite process of lithography and coating, and multiple spectral channels are integrated in different spatial locations on a single substrate. Each channel is spatially aligned with high accuracy on the basis of excellent spectral characteristics.
