If I was to categorize the machine vision questions I get, number two on the lens would be optics. Every camera system needs a lens, but lens nomenclature makes no sense to the typical vision user. In an effort to help, periodically I direct readers to the best lens calculator package I know of – MachVis, buried deep on the Qioptiq website – but sometimes that’s not enough. What’s needed is a simple optics primer.
It seems the folks at Basler have reached the same conclusion, because they’ve recently put a two page white paper titled “Optics Recommendation” on their website. It’s not the definitive guide, but it might help you on your way.
And what do I get most questions about? That would be lighting.
