Low Distortion Lens – S08012504018

S08012504018 is 1/2.5″ 8mm High-resolution low distortion lens, Low F-number S-Mount wide-angle lens (F1.8), 5MP resolution CCTV HD lens.

8mm 5MP M12 Low Distortion Lens

This 8mm 5MP M12 low distortion lens is designed for compact imaging systems that require detailed close-range imaging with controlled optical distortion. Its 50° diagonal field of view provides a more focused perspective than wide-angle M12 lenses, making it suitable for applications where the camera needs to concentrate on a specific object or working area.

With a 1/2.5″ image format, 5MP resolution, <-7% distortion, F1.8 aperture, and M12×0.5 mount, this fixed focal lens provides a practical combination of image detail, optical control, and compact mechanical integration. Its particularly short 0.1m minimum object distance further expands its suitability for close-range industrial and embedded vision applications.

This lens is an option within TOWIN’s M12 Lenses portfolio for customers looking for compact industrial M12 lenses, machine vision lenses, and low distortion fixed focal lenses.

M12 Low Distortion Lens Core Highlights

• 8mm Fixed Focal Length — Provides a focused viewing perspective for targeted imaging and close-range inspection.
• 5MP High-Resolution Imaging — Captures useful image detail for inspection, recognition, and embedded vision applications.
• Low Distortion Design — TV distortion below -7% helps maintain more natural object geometry than highly wide-angle optical designs.
• 0.1m Minimum Object Distance — Supports very close-range imaging where the camera must observe small or nearby targets.
• F1.8 Aperture with M12×0.5 Mount — Combines useful light-gathering performance with a compact interface for embedded camera systems.

M12 Low Distortion Lens Applications

Core Application Scenes

The key advantage of this 8mm M12 low distortion lens is its combination of a relatively focused field of view and an exceptionally short 0.1m minimum object distance. Rather than being designed primarily for large-area surveillance, it is better suited to applications where the camera needs to observe a defined target from a short installation distance.

For compact industrial inspection, the lens can be positioned close to components, product surfaces, connectors, labels, or mechanical assemblies. Its 5MP resolution provides useful image detail, while the <-7% distortion specification helps maintain more controlled object geometry across the image.

In embedded machine vision, the 8mm focal length provides a practical option when a camera must concentrate on a specific inspection region instead of capturing an excessively wide background. This can be useful for equipment status detection, component presence checks, product identification, and localized quality-control tasks.

The short 0.1m MOD also makes the lens suitable for close-range equipment monitoring. Cameras can be installed within compact machinery or near production equipment where the distance between the lens and target is limited.

For robotics vision, the lens can support targeted observation of robotic work areas, grippers, components, and nearby objects. Its more controlled field of view can be advantageous when the vision system needs to focus on a defined workspace rather than maximize environmental coverage.

Close-Range Imaging Advantage

The 0.1m minimum object distance is one of the most important differentiating features of this lens.

Many compact camera systems are installed close to the object they need to observe. A lens with a longer minimum object distance may not be able to focus effectively on these nearby targets. This 8mm M12 lens is specified for a minimum object distance of only 0.1m, making it particularly useful for short-distance imaging.

Potential applications include:

• Component presence inspection
• Connector and interface inspection
• Small-part observation
• Product label recognition
• Equipment status monitoring
• Robotic gripper observation
• Near-field industrial imaging

The actual image size and coverage at 0.1m will depend on the sensor and complete camera configuration, so application-specific testing is recommended for critical inspection projects.

Controlled Distortion for Industrial Imaging

With TV distortion below -7%, this lens provides a more controlled optical perspective than extreme wide-angle M12 designs.

This characteristic can be valuable when the imaging system needs to preserve the apparent shape of objects and maintain consistent visual geometry. It is therefore more appropriate for targeted inspection and recognition tasks than a fisheye-style lens designed primarily for maximum scene coverage.

However, the lens should not automatically be considered a metrology-grade optical system. For precision measurement, the complete camera system should be calibrated and validated according to the required measurement accuracy.

Optical Integration

The lens uses an M12×0.5 mount and has a total track length of 23.20mm, making it suitable for compact camera assemblies where optical space is limited.

The F1.8 fixed aperture provides useful light-gathering capability for indoor industrial environments and embedded vision systems. Lighting conditions, sensor sensitivity, exposure settings, and image-processing algorithms should all be considered when evaluating final image performance.

Its 6G optical construction provides the optical configuration specified for this model.
