Dear colleagues,
I have a revers eye model in zemax which I should optimize it to reach the paper mentioned curve of MTF( by changing conic constant of back lens and thicckness of vitreous) but strangly my diffractio limitted MTF has lower heignt (in 50cycle per degree Mtf=0.4). in the mentioned paper it has in 50 cyclee per degree MTF=0.5. What is your idea to improve my diffraction limitted curve of MTF to higher height?
Please check all the parameters of your Zemax model: pupil diameter, actual wavelength, actual media properties, especially wavelength dependences of the refraction indexes. May be the reason of the discrepancy is quite simple.
As I can see resolution of 50 cycles per degree is rather high for normal human eye and MTF for real eye will sooner be lower than 0.5 at 50 cpd.
Maybe you could increase the iris diameter in order to increase the MTF diffraction limit.
