Can someone just review my numbers and see where I went 1/3 wave off?
Pin location /Moving slitless readings
I had used the star test to correlate my figuring earlier, and when I saw it had some discrepancies, I doubted my results, and started relying on the easier method of figuring to the above program.
I started using Figure XP, and I get the same results...should have been an exceptional mirror. See picture.
I set up my Caustic tester, and it's showing the error. Closer star testing does show error.
So why are these Foucault programs giving me bad numbers?
Could I have misinterpreted the term "effective radius"? Isn't that the center of a mask aperture or exact pin location?
I must be a dummy. Calculating r^2/2R gives me about 80% smaller readings. Why didn't I just do it the old way and skip the software?
