In the majority of image processing tasks, the parameters object size and working distance are fixed. In these cases, C mount lenses with fixed focal distance and manually adjustable focus are preferred.
However, if the object size and/or the working distance in an application are variable, the focus of the lens must be adjusted quickly. The application software should ideally perform this adjustment dynamically using auto-focus. To do this, the focus must be motorized. Here you will find wenglor cameras with an integrated autofocus lens.
