Why Use Telecentric Lenses ？Superior Stability and Consistency

An optical lens is an imaging device with many variable parameters. Aperture, focal length, object distance, back focus, magnification, and other parameters can all be adjusted. Any change in one of these parameters can affect image quality. In machine vision projects, industrial lenses often require specialized engineers to adjust these parameters to ensure that the captured images meet the software's computational requirements. This adjustment process is usually time-consuming and meticulous, requiring repeated steps to determine the optimal settings.

Telecentric Lens

In vision inspection, efficiency, accuracy, and simplicity are key indicators of a successful project. The stability of image quality in the entire vision hardware system directly determines the consistency of inspection results. In industrial fields, especially in high-volume production environments, stability is paramount. The inspection process should avoid all possible sources of variability. Traditional industrial lenses with adjustable parameters can be potential hazards in industrial settings. To mitigate these issues, telecentric lenses are designed with fixed settings, eliminating any variables after calibration. Users only need to install them in place without any specialized tuning.

One important optical feature of a telecentric lens is that the magnification remains constant within the depth of field, so to ensure proper installation, users only need to check if the image is in focus. Additionally, telecentric lenses have a deep depth of field with stable optical characteristics within this range, making it easier for users to quickly find the correct position.
