I
see far too many vision applications that should use telecentric
lenses but don’t. I imagine this is because: (a) telecentric lenses
are expensive, and (b) not many people understand what telecentric
imaging can do for them. I can’t do anything about (a) but I can
help with (b).
Opto-Engineering
have on their website a telecentric
tutorial
titled, “TELECENTRIC LENSES: BASIC INFORMATION AND WORKING
PRINCIPLES” (the capitals are theirs). This does it exactly what it
says, so I suggest everyone take a few minutes to expand their
knowledge by clicking on that link.
I
may set a test, so study hard!

In addition to the mentioned tutorial, I'd recommend to take a look at the application notes as well as the video tutorial for telecentric lenses for additional information and useful application examples: http://www.opto-engineering.com/matrix-detector-telecentric-lenses.html
