The focal length of each lens can be calculated using the following equation: f= (R1*R2)/((n-1)*(R2-R1)). where n is the index of refraction and R1,R2 is the radius of curvature for each surface of the lens. They can be also coated with MgF2 to protect the surface or AR coated to increase the transmission.
