The main difference between Prime Lenses and Zoom Lenses is focal length. A prime lens is a fixed focal length lens, whereas a zoom lens has a focal length range that can be adjusted using a mechanism such as a ring that can be moved clockwise or counterclockwise. Industrial lens is applied widely in machine vision imaging systems. Industrial lenses include prime lens, bi-telecentric lens, telecentric lens, zoom lens, etc. Today, we will talk about two main types of lenses, Prime Lenses and zoom lenses.  For industrial applications, a camera is generally preforming a repetitive task and is often fitted with a prime lens. However, for applications where the camera must image objects of varying distances, a zoom lens is installed. A comparison between a prime and zoom lens is shown below. Since Zoom Lens are capable of a range of focal lengths. it offers a greater degree of flexibility. To adjust focal lengths, a lens system normally has more optics and moving pa...
