Plano Concave Cylindrical Lens
Plano-concave cylindrical lenses provide uni-axial negative imaging for anamorphic beam expansion and a wide range of applications.Plano-concave lens is the most common item used for light projection and beam expansion. Coated with antireflective coatings, lenses are used in various optical systems, lasers and assemblies. Catalog items list consist of most common diameter and focal length uncoated lenses made from BK7; UVFS; CaF2 and ZnSe.
Plano Concave lenses have one flat and one inward curved surface. Plano Concave lenses have a negative focal length and are used for image reduction or to spread light.
Rod Lenses are polished on the circumference and ground on both ends. Optical performance is similar to a cylinder lens.

Collimated light passing through the diameter of the rod lens will be focused into a line. N-BK7 and UV Fused Silica substrates are available for a variety of UV, Visible and NIR applications.Designed for use in a variety of laser and imaging systems, these components are available in a range of micro sizes for
integration into a host of OEM applications. Custom sizes, variations in polishing/ ground surfaces and additional coatings are
available upon request, please contact our Sales Department for details.
As a major importer of renewable resources (waste raw materials), China has more than 3,000 waste raw material processing enterprises, and the number of imported waste plastics processing and utilization enterprises is the largest, nearly 1,600. The import volume of waste plastics accounts for 25% of the total annual import of solid waste, about 8 million tons per year. At present, there is an uncontrollable change in the price of classified waste plastics.
There are two main reasons for the increase in the import volume of waste plastics in China: First, the recycling system in China is not perfect, and the garbage classification awareness of the whole society needs to be improved. This has caused the classification and recycling of waste plastics in China to stay in the original family. At the small workshop stage, and because the recycling of domestic waste plastics relies on a large amount of manpower, the price is higher than the price of imported waste plastics. Second, at present, China is facing the recycling of waste plastics at the macro level, mainly relying on the exemption of some taxation and other economic means, lack of specific policy support, lack of technical specifications for the classification of waste plastics, and lack of enterprises that purchase waste plastics and meet product safety requirements. Identification and encouragement. These have led to the long-term low level of waste plastic recycling industry, it is difficult to form a scale of sustainable development, which makes it difficult to find large stable sources of waste plastics in China, but the current trend of classified waste plastics prices has been obtained control.
