A Simple Guide to Machine Vision Lens and Telecentric Imaging Lens Technology

Image
The use of lenses is one of the most important elements that enable machine vision to be an integral part of many industries today. A machine vision lens captures highly accurate, clear, and detailed images of objects for use in inspection and automation processes. Unlike regular camera lenses, machine vision lenses are designed specifically for high-speed production situations where there are varying illumination levels and a need for accurate focusing with very tight tolerances. Using a machine vision lens will give you sharp, consistent images for tasks such as checking small parts, reading bar codes, or inspecting the quality of a package.   A Telecentric lens is a type of Machine Vision Lens and is often regarded as the most useful and progressive lens in the Machine Vision industry. The main difference between telecentric lenses and conventional machine vision lenses is the absence of perspective distortion. The result of this is that no matter how distant or close the ...

Telecentric Imaging Lens Generates Clearer Image Without Distortion

Image
  For capturing any view with high accuracy and no distortion, try a telecentric imaging lens . These are the high-end lenses that offer excellent visualization for any view. These offer the same-sized image of an object, irrespective of the object’s distance from the camera, and they don’t even compromise in quality.  In other words, telecentric lenses are specialized optical lenses that maintain the image size no matter how far the object is from the lens. Therefore, they are widely used in applications or industries where accuracy and precision are vital. For example, in manufacturing, electronics, and medical imaging.  A telecentric imaging lens ensures that light rays entering the lens are parallel to the optical axis. This design eliminates perspective errors, meaning objects don’t appear larger or smaller when they move closer or farther. Result in accurate, repeatable measurements and low distortion imaging. In such applications, minor detailing can cause a maj...
