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.
