The difference between fixed focus lens and zoom lens

 The difference between fixed focus lens and zoom lens

Industrial lenses are widely used in machine vision imaging systems. Industrial lenses include fixed-focus lenses, bi-telecentric lenses, telecentric lenses, zoom lenses, etc. Today we at phonefix will tell you about two main types of lenses, fixed-focus lenses and zoom lenses.

What is a prime lens?

A prime lens is a lens with a fixed focal length, which means that such a lens has a fixed angle of view that cannot be changed -- you cannot make the image appear larger or smaller in the frame unless you move it.

What is a zoom lens?

A zoom lens, on the other hand, has a variable focal length. By turning the zoom ring, you can move the optics inside the lens to obtain different perspectives.

The main difference between prime and zoom lenses is the focal length. A prime lens is a lens with a fixed focal length, while a zoom lens has a range of focal lengths that can be adjusted using a mechanism such as a ring that can be moved clockwise or counterclockwise.

For industrial applications, cameras typically perform repetitive tasks and are often equipped with fixed-focus lenses. However, for applications where the camera must image objects at different distances, a zoom lens is required.

Prime Lens has fewer components, so it's often the more affordable option. This simplicity can lead to better quality, since fewer variables mean less chance of problems in the manufacturing process.

Because the zoom lens has a certain focal length range. It provides a greater degree of flexibility. To adjust focus, lens systems typically have more optics and moving parts that help focus light within the lens to different locations. This added complexity increases the cost of the camera lens.

Application fields of zoom and fixed focus lenses:

Machine vision lenses, industrial camera lenses, for visual inspection/detection, visual positioning. Robotic automation, industrial automation.

Industrial camera lenses for visual inspection and automation, robotics, industry 4.0, visual recognition, visual recognition

However, as time goes by, lens technology continues to improve, and industrial cameras

The quality gap between prime and zoom lenses in devices continues to narrow. This ensures that even with the stringent optical requirements of the application, it is usually safe to consider both prime and zoom lenses.

We  phonefix shop can provide various lenses such as industrial monitoring and industrial identification.
