Corretive Calculations and Adjustments

Calculations help determination that e extent of aberrations and confireate acculpe. For example, spponercal aciration cae estimatech using the lensharker 's formula:

1f 1f; FLT: 0 123; Aver3; R = (n - 1) * (1 / R1 - 1 / R2) 1f; FLT: 1 1f 3; 1f 3; 3;

where R is the focal lengdh, n is the refactire index, and R1 and re radie of curvature of the lens surfases. Adjusting the radie or using aspheric elemens can reduce averhios.
