Tolerancing an optical design is vital when optical modules are produced in tens of millions. In these cases the
production yield is all-important: it will decide if the product will be a success. While optical design softwares provide
powerful tolerancing tools, to get an idea of what the production yield will be, we will have to go a step further. A way
of taking this step consists in a tolerancing procedure that will use these tolerancing tools and a dedicated analysis
- A list of specifications that the lenses will have to fit into has to be established.
- A merit function that will calculate each of these specs will have to be written.
- For the tolerancing itself, a script will have to be used to write to an output file all these values for each lens
created during tolerancing
- The analysis software will read the output file, make all the desired statistics and then give the production yield and other relevant informations (e.g. yield and behavior of any spec)
