The urea market is boosted mainly by stabilization

The urea market is mainly stabilised

The overall domestic urea market is relatively stable. In some regions, sales are still relatively light, and manufacturers' prices have steadily declined. Most of the manufacturers in Shandong are still exporting orders, and sales in the local market are still unstable, and the export orders of individual manufacturers have been implemented to the end. The pressure has gradually increased, and the factory prices of some manufacturers have dropped by around RMB 10-20/ton. The price is around 1540-1550 yuan/ton. In the Hebei region, the local sales market remained weak, most of the manufacturers were export-oriented, and some manufacturers had a small amount of new export orders. However, the transaction price was not ideal, and the combined factory price was only around 1490-1510 yuan/ton. The overall market in Henan Province continued to be stable, with most manufacturers' factory prices not changing so much. The actual sales price was around 1,560 yuan/ton, and the low-end turnover was about 1,540 yuan/ton.

In the recent continuous rains in Anhui Province, manufacturers took the goods to a certain extent. Some manufacturers steadily dipped to attract orders. The actual sales price is now around 1,600-1630 yuan/ton, while the factory prices of some manufacturers in northern Jiangsu and southern Shandong are down 10%. Around RMB/ton, the actual sales price is only around RMB 1,600-1610/ton. Manufacturers' prices in Northeast China continued to be stable. Some manufacturers in Jilin and Liaoning Province still kept orders for light storage in the previous period. Individual manufacturers in Jilin Province had already started ignition and were preparing to resume production. The orders for goods in Heilongjiang region were still available, but due to some manufacturers 10 The tentative price increase for the month was relatively large, reaching around RMB 60/ton, which resulted in fewer transactions in orders in October. The current price of small granule urea mainstream ports is around 1620-1640 yuan/ton, the number of new export orders is small, the actual price is low, and the local sales market cannot bring strong support. Therefore, the prices of some manufacturers have fallen steadily and steadily. , Or directly down, but in recent days some of the ports have cargo ships to Hong Kong, the pressure on the Hong Kong or will be eased. In a comprehensive view, it is expected that the domestic urea market will continue to be stable in the short term, and local quotations may fall steadily, while individual manufacturers with better export prices may rise, but the space is limited, and it is difficult to boost the overall market.

Meniscus Cylinder Lens

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.
Fused silica cylinder lenses are ideal for demanding laser machining and medical applications.
