Wide Angle Lens – C0411820M5

Le C0411820M5 est un objectif grand angle manuel à monture C 1/1,8″ 4 mm, à faible distorsion (<0,5 %) pour la vision industrielle, F2.0-C, haute résolution 5 mégapixels.

4mm C-Mount Wide Angle Lens

This 4mm C-Mount wide angle machine vision lens is designed for 1/1.8″ sensors and 5MP industrial cameras requiring broad image coverage with controlled distortion. With a 94° diagonal FOV, 83° horizontal FOV, <0.5% TV distortion and a 0.1m minimum object distance, it is well suited for close-range factory automation, machine vision and industrial imaging systems.

For guidance on matching image sensors with suitable optical formats, see the Sensor Guide. For broader lens selection considerations, the Lens Selection Guide provides additional reference information.

Product Core Highlights

• 4mm wide-angle optical design for broad scene coverage.
• 94° diagonal FOV for capturing a large imaging area.
• 5MP resolution for detailed industrial image acquisition.
• <0.5% TV distortion for controlled geometric representation.
• 0.1m M.O.D. for close-range inspection and compact installation.

The combination of a short 4mm focal length and broad FOV allows this wide angle lens to cover a larger inspection area without requiring the camera to be positioned far from the target. Its low distortion specification also helps maintain more controlled image geometry than conventional wide-field optics.

C-Mount Wide Angle Lens Applications

Core Application Scenes

This 4mm industrial lens is particularly suited to machine vision installations where the camera needs to capture a broad area from a relatively short working distance. The 83° horizontal FOV lets one camera cover a large section of a nearby inspection zone. Engineers benefit from this design when tight space separates the camera and production equipment.

For factory automation, the lens can be positioned above or beside a production station to monitor larger components, assemblies, work areas or multiple objects within one image. The 0.1m minimum object distance also makes it suitable for compact inspection setups where the camera must operate close to the target.

The <0.5% TV distortion specification is particularly relevant when using a wide-angle optical system in applications where excessive geometric deformation could make image interpretation more difficult. The lens targets wide-area industrial imaging instead of precision metrology, yet its controlled distortion preserves a more usable representation of the captured scene.

The 5MP resolution provides sufficient image detail for general visual inspection, object presence detection, positioning and automated image analysis. The F2.0–C manual aperture also allows integrators to adjust light transmission according to the illumination available at the inspection station.

For applications where the required image coverage needs to be estimated from sensor size, focal length and working distance, the FOV Calculator can be used during the initial optical design stage.

Designed for wide-area factory automation, close-range machine vision and compact industrial inspection applications.
