Double Concave Lenses

Double Concave Lenses

Double-Convex lenses (DCX) are used in image relay systems, or at near conjugates to imaging objects. DCX, together with two convex surfaces with equal radii, have positive focal lengths. In a variety of industries or applications, DCX lenses are used.
Z-Optics offers a wide range of Double-Convex lenses to maximize performance
