Hi! I know Zemax has up to 231 Zernike terms for Zernike Standard sag value but I can’t find the Polynomial formula for terms higher than 37. Is there any way I could find what is the mathematical formula for higher order terms? thanks!

Hi Nafiseh, try https://en.wikipedia.org/wiki/Zernike_polynomials, it gives the general convention.


Thanks but I am looking for a table with all of the terms. CodeV and Zemax have two different coefficient orders and I usually look at the formula to find which order they are using, 


Sorry, I misunderstood your question.

Go to Analyze...Wavefront...Zernike Standard Coefficients and set the maximum term to 231. The listing will give the functional form for each term, for example:


Z 226        0.00000000    :      42^(1/2) (190p^20 - 342p^18 + 153p^16) * COS (16A)

Z 227        0.00000000    :      42^(1/2) (190p^20 - 342p^18 + 153p^16) * SIN (16A)

Z 228        0.00000000    :      42^(1/2) (20p^20 - 19p^18) * COS (18A)

Z 229        0.00000000    :      42^(1/2) (20p^20 - 19p^18) * SIN (18A)

Z 230        0.00000000    :      42^(1/2) (p^20) * COS (20A)

Z 231        0.00000000    :      42^(1/2) (p^20) * SIN (20A)

 


got it thanks!
