Double Convex Lenses, Bi-convex Lenses have two outward curved surfaces, a positive focal length and are useful for 1:1 imaging and in multi-element systems.These lenses are designed to have a focal length of f= (R1*R2)/((n-1)*(R2-R1))
- Supported by the Zemax Optical Design Package
- Posistive Focal Length
- Material upon requirement
