Low Distortion Lens – S08012504028

S08012504028 is 1/2.5″ 8mm low distortion lens for Drones, IR Corrected M12 mount lens, fixed iris F2.8, high resolution 5 Megapixel CCTV lens.

8mm 5MP IR Corrected M12 Low Distortion Lens

This 8mm 5MP IR corrected M12 low distortion lens is designed for compact camera systems that require detailed imaging, controlled optical distortion, and consistent performance across visible and near-infrared imaging conditions. With a 1/2.5″ image format, 50° diagonal FOV, and 5MP resolution, it provides a focused viewing perspective for industrial, machine vision, security, and embedded imaging applications.

The lens combines an 8mm fixed focal length, <-7% distortion, F2.8 aperture, 0.1m minimum object distance, and M12×0.5 mount in a compact optical configuration. Its IR corrected design makes it particularly useful for camera systems that switch between day and night imaging or use near-infrared illumination.

Compared with ultra-wide M12 lenses, the 8mm focal length provides a more concentrated field of view, making it suitable for applications where the camera needs to focus on a defined target area. The 0.1m MOD also supports close-range imaging where the lens must be positioned near the subject.

M12 Low Distortion Lens Applications

Core Application Scenes

This 8mm IR corrected M12 lens is designed for imaging systems where the camera must capture a defined target area while maintaining stable optical performance under different illumination conditions.

The IR corrected design is particularly useful in day/night security and near-infrared imaging systems. When a camera uses an IR illuminator at night, the effective focus position of different wavelengths can vary in conventional optical systems. An IR corrected lens is designed to reduce this focus shift and help maintain usable image sharpness when the imaging system transitions between visible and near-infrared light.

For industrial machine vision, the 8mm focal length provides a relatively focused field of view that is useful for observing a specific inspection region rather than an entire large scene. The 5MP resolution can support detailed detection and recognition tasks, while the <-7% distortion specification provides controlled image geometry.

The 0.1m minimum object distance makes this lens especially useful for close-range inspection. It can be positioned near components, product surfaces, machine interfaces, labels, connectors, and other small targets where installation space is limited.

For smart security, the combination of 5MP imaging, moderate FOV, low distortion, and IR correction makes the lens suitable for compact cameras that need reliable daytime and nighttime imaging.

Designed for close-range machine vision, day/night security, and IR-assisted industrial imaging applications.

Low Distortion Imaging

The lens provides a specified distortion of less than -7%, giving it a more controlled optical profile than extreme wide-angle designs.

This can be useful for industrial imaging applications where excessive geometric deformation may affect object recognition, positioning, inspection, or image analysis.

The 40° horizontal FOV is particularly suitable for targeted imaging. Rather than maximizing the amount of environment captured by the camera, the lens provides a more concentrated view of the intended subject.

For applications where distortion must be carefully evaluated against FOV and focal length, refer to TOWIN’s Distortion Guide.

Optical Integration

The lens uses an M12×0.5 mount with a total track length of 23.10mm. This compact mechanical configuration is suitable for embedded cameras and space-constrained optical assemblies.

The F2.8 fixed aperture provides a stable optical configuration without requiring an adjustable iris mechanism. This can simplify integration into compact camera designs where a fixed optical configuration is preferred.

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