Can you plz guide that how distortion helps to improve relative illumination.AS in Zeemax document i read that as we move photodiode towards the edge of the image then brigtness decreases due to obliquity fcator no matter how uniform and good source and perfect lens we have .So decrease in relative illumination can be compensated by distortion
