Greetings all,
I will need to test a convex sphere in the hopefully close future. I have
never done this before so can the ronchi test be used and if so how?
Thinking about it would seem that the reflected light source would be
spread rather than come to a focus. Is there any easy way to test for a
convex sphere? Many thanks
Charles
