| Product List | 
Double-Convex Lenses are used in image relay applications, or for imaging objects at close conjugates. Double-Convex Lenses have positive focal lengths, along with two convex surfaces with equal radii. Aberrations will increase as the conjugate ratios increase. DCX Lenses are used in a range of industries or applications.

Optical AR Coatings
a) Uncoated,The surface reflectivity of uncoated visible lenses(Refractive index=1.5) is about 4%.
