Lenses are critical part of vision systems. Imaging optical device, lens, and sensor needed to acquire an image of enough quality so that the inspection task can be satisfactorily accomplished. The key lens characteristics,such as field of view, working distance, resolution, contrast, depth of field, image circle, distortions,NA and modulation transfer function are important factors to be considered when choosing a lens for a camera. Unfortunately, these data are not always made readily available to vision engineers.
We at Vital Vision recognize such limitations, and we aim to bridge this gap with our pre-sales support activities and testing services.
