spherical lens
Jilin Tianhua Opto-electrical Technology Development Co., Ltd., production and sale of precise optical elements. Our company locates in Changchun City, Jilin Province, the optical base of China. We specialize in cylindrical lenses. The plano-concave lenses are made from various material, which are manufactured with one concave surface and one plane surface. These lenses have negative focal lengths. These lenses diverge collimated incident light. They form virtual images which are seen through the lens. They are often used to expand light or to increase focal lengths in existing systems. We also offer precision grade plano concave lens with tighter manufacturing tolerances
