By changing the focal length of the lens, different sizes of field of view (FOV) can be obtained.

Machine vision obtains the required information or is a device used to control machine movement by analyzing images. It collects image information through image sensors such as industrial cameras, and controls the subsequent process actions of automated equipment by analyzing and processing the converted image information.
Industrial lenses are very important imaging components in machine vision systems. If the system is to fully play its role, industrial lenses must meet the requirements. With the widespread application of machine vision systems in the field of precision measurement, ordinary industrial lenses are difficult to meet the requirements, and telecentric
Defect detection is the most important component of industrial vision technology. Industrial vision cameras are divided into area array and line array, and the camera must also be equipped with a light source and lens to form an imaging system.
Aperture adjustment is very important, as it can control the amount of light entering and adjust the exposure. At the same time, reducing the aperture can increase the depth of field of the system and improve the quality of imaging.
