Meniscus cylinder Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus cylinder Lens is used to increase the focal length of another Cylindrical Lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the cylindrical lens.
Some styles of cylindrical lenses have antireflective coatings to increase the transmission of light through the lens.

Xinjiang Karamay will build the largest building materials city in Xinjiang
The reporter learned from the Economic and Trade Commission of Karamay City, Xinjiang that a Xinjiang Karamay International Home Building Materials City project integrating product display, warehousing, logistics and international trade will be officially started construction in April 2012. The total investment of the project is expected to exceed 6 billion. For the third phase of construction, the project is expected to complete the construction within 3 to 5 years. At that time, Karamay International Home Building Materials City will become the largest building materials city in Xinjiang. Gui Bin, deputy director of the Karamay Economic and Trade Commission, said: "The construction of the Karamay International Home Building Materials City project aims to improve the comprehensive quality of Karamay City, improve the current state of scattered operation of the home and building materials industry, and facilitate the development of the local people in the oil city and promote local economic development. At the same time, promote the development of the home building materials industry to cluster and high-end, and finally make Karamay International Home Building Materials City the largest, most radiant and highest-grade home building materials distribution center in the northern Xinjiang region, and promote the development of Karamay's emerging tertiary industry." It is understood that Karamay International Home Building Materials City is located in the southeast of Chengnan New District, Karamay City, Xinjiang, north to the South Ring Road, east to Shengli Road, west to Huancheng East Road, with a total planned area of ​​about 66.60 hectares. Zhu Dingmao, Chairman of the Board of Directors of Jiangxi Huifeng Optoelectronics Group, an investor in Karamay International Home Building Materials City, said that Karamay is located in the central region of Eurasia - Pan-Central Asia, including Central China, Central Asia, West Asia, South Asia and Russia, Siberia. area. Four-fifths of the world's population is concentrated in this area, and Karamay is in the heart of the populated area. After the Karamay International Home Building Materials City is completed and put into use, it can radiate to surrounding cities and connect to a wider overseas market. Preparations are currently in progress.
