In the industrial automation production process, vision inspection is a very important technical means to greatly improve production efficiency and product quality. Character label inspection is an important application scenario in vision inspection, which is mainly used to identify and detect character labels on products to ensure product quality and production process traceability.

Choosing the right industrial lens is a critical aspect in character label inspection. Telecentric lenses are a very suitable industrial lens for character inspection. Telecentric lenses have the following advantages:

1. High resolution: telecentric lens generally has a high resolution, can clearly capture the details of the character labeling information to improve detection accuracy.

2. Small aberration: telecentric lens has small aberration, which can ensure the accuracy of the detection results.

3. Large aperture: telecentric lens has a large aperture, can adapt to different lighting conditions under the character label detection, improve the reliability of detection.

4. Large depth of field: telecentric lens has a large depth of field, can be clearly captured in a wide range of character labeling information, improve the adaptability of detection.

In character label inspection, these advantages of telecentric lenses can help improve inspection accuracy, reliability and adaptability, thus ensuring product quality and improving productivity. Therefore, in the visual inspection project, choose the right telecentric lens can better meet the needs of character label inspection.
