From reverse projection to modulation transfer function testing, there is more than one way to evaluate the resolution of a lens.Patrick McKenna, edmund optics inc.In the days of VGA video cameras and predominantly analog storage, it was easy to make an imaging lens that would outperform the camera’s ability to capture an image. That’s no longer the case. Where 640 pixels once stood, it is not uncommon today to see 6 million. Cameras continue to...Read full articleRelated content from Photonics MediaARTICLESFor Carmakers, Inspection Flexibility Makes the DifferenceBuilding a car is a complex process, and it’s getting more complex every year.
