Meniscus Lenses: The Positive Meniscus can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the lens. The meniscus lens plays a divergent role in the optical path, and is commonly used in photographic system, objective lens system and laser measuring system.
We supply kinds of Plano-Convex Spherical Lens,Plano-Concave Spherical Lens,bi-convex Spherical Lens,bi-concave spherical lens,meniscus spherical lens,special spherical lens,achromatic spherical lens,ball lens,sphere lens etc.

In order to ensure the smooth export of furniture to Egypt, the staff of the Suzhou Bureau visited the company many times and informed the exporting Algeria of the matters needing attention when preparing for inspection, so that the company could timely understand the methods and regulations of furniture export inspection and quarantine in Algeria, and actively help the enterprise to contact the pre-shipment inspection Matters. At the same time, in strict accordance with the relevant regulations, on-site inspection of the batch of furniture is carried out, and the control of harmful organisms and toxic and hazardous substances is done to ensure the quality and safety of exported furniture and help enterprises to export smoothly.
The Suzhou furniture manufacturing market is mature, the product quality is stable, and the prices are competitive. Over the years, there have been no cases of overseas returns due to product quality issues. However, due to the impact of domestic and foreign economic situations, Suzhou ’s furniture exports were blocked in 2013. Furniture export companies actively sought new channels for foreign sales and explored new markets. Egypt, Algeria and other African countries have gradually become new targets for export furniture companies. Export provides a new development direction for furniture export enterprises.
