C-Mount Lens – C2012028M25

Le C2012028M25 est un objectif à monture C de 20 mm de focale, un objectif à faible distorsion pour la vision industrielle, un iris manuel et un objectif industriel haute résolution de 25 mégapixels.

Il convient de tenir compte des différentes valeurs de champ de vision (FOV) pour les capteurs de 1,2 pouce et de 1,1 pouce lors du choix de la caméra et de l’objectif. Les ingénieurs peuvent utiliser le calculateur de champ de vision pour évaluer la couverture de l’image en fonction de la taille du capteur, de la focale et de la distance de mise au point.

C-Mount Low Distortion Lens Applications

Core Application Scenes

This 25MP low distortion machine vision lens is designed for industrial imaging applications where both image detail and geometric accuracy are important. Its ultra-low TV distortion of below -0.1% helps minimize geometric deviation across the captured image, making it particularly valuable when the vision system needs to analyze object dimensions, edges, alignment, or relative positions.

For precision factory automation, the 20mm focal length provides a controlled viewing angle while the 25MP resolution captures fine structural details. This makes the lens suitable for inspection of mechanical components, electronic assemblies, precision parts, and other manufactured products where small visual defects or dimensional differences need to be identified.

The support for both 1.2-inch and 1.1-inch image formats also gives system integrators more flexibility when selecting a high-resolution industrial camera. The 1.2-inch configuration provides a 51.5° diagonal FOV, while the 1.1-inch configuration provides a 47.5° diagonal FOV, allowing the same optical platform to be evaluated with different large-format sensors.

In automated measurement and positioning systems, the extremely low distortion can help maintain a more consistent relationship between the captured image and the physical geometry of the inspected object. This can be useful for dimensional verification, component alignment, edge detection, PCB inspection, and automated quality-control workflows.

For engineers developing complete Machine Vision Solutions, this lens provides a high-resolution optical configuration for applications where conventional lower-resolution lenses may not provide sufficient image detail.
