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.
