Quote: What new theory are you trying to prove with a Hypo Dialyte ? The math discriping the interaction of light with refractive and reflective surfaces has been well established and tested many times. So unless there is a bug in the software of both OSLO, Zemax or any other raytracing program, they predict the results extremely well of any optical design that uses these materials. There are millions of designs to prove this. So why should one throw all that data away and experiment with a design that using these proven tools that shows it not to have very good performance ? - Dave
Quote:Surfaces are 7 in total. Is understood: there are three elements. Please, see this new drawing: I went down the "scroll bar" on DBoptics.By other hand: is important I say: the sketches above are referring to dialyte Petzval. These drawings do not refer to Hypo.
