You are the system engineer on a project which will image a field of object points radiating at a wavelength lambda in order to couple the light into a 2D array of single mode fibers. The dominant wavefront error is field curvature, described by a wavefront coefficient, W220. The exit pupil of the lens has radius R. Write an equation for the maximum field size that will enable fiber coupling efficiency of at least 17 across the entire field. Hints: 1. You will need to calculate the RMS wavefront error value from the wavefront error function in the pupil AW You will first have to calculate the mean of this wavefront error over the pupil, W then calculate the RMS wavefront error as 1||;" (\\W W}Q where T represents the mean of T over the pupil. 2. Remember in the expression for Strehl ratio that w is given in units of waves. 3. Express your answer in terms of the variables given, that is lambda, N (for 17), R, and W220. Since the various roots in this answer can confuse the autograder, please use abs() around each variable
