Circuit Board Inspection


A lens designed to inspect circuit boards to look for faulty components without introducing off-axis views


To design and manufacture a lens with very low distortion, a very short working distance, and a large depth of field.


Design:An “uncommon” telecentric lens design; regardless of the deviation from the central optical ray, the components imaged on the circuit board remain equally in perspective.


Integration::Integrated with a 28.7mm line scan camera provided by the customer.
Testing:While at first the testing of all lenses was done at our customer, it was later found that COI could preform the QA on this lens more efficiently in-house, so all testing and certification eventually was done at COI.
