The intent in pairs is to circularize a beam (collimation can be done too). My intent is to tame the fast axis to achieve a square or square(ish) beam vs the rectangle normally seen. I do think it would work. I've looked for experimental grade C lenses but not found any to test the idea.How so? Can you make just one of the lenses do the same job as a pair? It seems the first lens expands the one axis and the other collimates it. Unless you are talking about a totally different lens.
If you're taking part in that C lens group buy test out the idea if possible.
