Quantité : 999

Cylindrical lenses are available in either plano-concave or plano-convex configurations from Crysmit, Plano-concave lenses have a negative focal length and are used for image reduction or to spread light. Plano-convex lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications.
