Hi ,

 

I tried to design a simple bi-vex lens with a curvature ratio of 6:1. I used CVVA, CVGT, CVLT and ABSO operands, but I couldn't match the desired 6:1 curvature ratio. Could you please guide me on how to achieve this specific curvature ratio using these lens design techniques?

I attached the design as well.

 

Thank you

Couldn’t you use a pickup on the radius of the second surface, to pick up from the first times a scaling factor?
