Clip summary all Tolerancer clips tell a friend

This is a basic introduction to tolerancing as a subject - it summarises what is covered in the WinLens Tolerancer manual.

For the optical engineer there are five key questions that need to be answered when converting a paper design into a successful product.

  • What are the errors that can happen in the manufacture of this design
  • What are the performance effects of those errors individually
  • What limits [tolerances] do I need to place on those errors
  • What will happen when I make a batch of lenses to those tolerances
  • How can I get the glass shop and machine shop to follow those tolerances

We discuss these very briefly!
