Details:

The cylindrical lens is designed for applications requiring one-dimensional shaping of a light source. They are offered in either plano-concave or plano-convex configurations, which are meant to expand or focus light, respectively.

From prototype to production, Focus Technology designs, manufactures, and coats cylindrical lenses. By the reason of ten years of experience in lens and skilled work forces in production, Focus Technology has the ability to offer cylindrical lenses at the lowest pricing with the fastest delivery times.
