Product Description
Optical Cylindrical Rod Lens and Large Cylindrical Lens with BK7 K9 Glass
Cylinder Lenses are offered in both plano-concave and plano-convex configurations, they are typically used to focus incoming light to a line, or to change the aspect ratio of an image. Cylinder Lenses are available with positive or negative focal lengths, they are used for the optics, lasers, medical science, electronics, tele-communication and others. We can offer cylinder Lenses include convex cylindrical lens, concave cylindrical lens, meniscus cylindrical lens, and doublet achromatic cylindrical lens ect. Choose from N-BK7 glass, UV fused silica, or CaF2, all of which are available uncoated or with an antireflection coating. We can provide various kinds of cylindrical lens with high precision, We are proud to be one of the few suppliers can detection the radius and flatness about the cylindrical lens in China. Absolutly can ensure all the products are qualified. | | |

Company Introduction:
Changchun Qianhao Photoelectric Co., Ltd was founded in 2002. Our company was separated from a big optical enterprise that controlled by the government. There are 5 workshops in our company. We can manufacture kinds of optical products and now we are reliable supplier for many countries.
Changchun is a famous optical city in China; We took part in the research of No. 5 Shenzhou Spaceship, and provided the optical parts of the spaceship. Products in China are always at a very competitive price. In fact we used to be OEM factory for many companies in Changchun and some other cities. But as the time being, we found the factory was controlled by the orders. So now we want to develop our own market. We got the advantage of price, since we were OEM
