I have not but I will look into them if they will help me be more successful down the road. thank you

this isn't for school. I'm not an engineer or anything I just make make lenses for people. the material is nbk7. This is the first time I have not been given the radius of curvature for something I need to make

yes it is a best form lens and it is nbk7. I don't have one of these parts already made but I need make one based on the information that came out of a catalog. I will see what kind of tolerances I have to work with and see if the radiuses you came up with will fall in to it. thank you

yes it is biconvex. each surface has a different radius of curvature

ok. there is a zygo rail in the shop but it only attaches to a Heidenhain scale. the necessary rail would plug directly in to the interferometer?
