Clip 1: PreDesigner: an introduction...
PreDesigner is for those learning lens design and for all optical engineers. It is useful at the beginning of a lens design project, when some basic optical requirements are known, and you want to find the unknown parameters of the lens and the system layout details, such as lengths, heights and magnification.
This clip shows how to use PreDesigner to answer your ‘what if’ questions and some of the other nice features within it.
