2.98mm M12 5MP Low Distortion Wide Angle Lens

This 2.98mm M12 low distortion wide angle lens combines a 100° diagonal FOV with distortion below -0.2%, providing broad image coverage while maintaining excellent geometric control. Designed for 1/2.5″ and 1/2.7″ sensors, its 5MP resolution, compact M12 × 0.5 mount, and visible/850nm dual-pass optical design make it well suited to advanced machine vision, embedded imaging, and near-infrared vision systems.

For system designers working with different sensor formats, the Sensor Guide can help evaluate sensor and lens compatibility. The Lens Selection Guide provides additional guidance when balancing focal length, field of view, distortion, and application requirements.

Product Core Highlights

• 100° diagonal FOV on 1/2.5″ sensors for broad scene coverage.
• Ultra-low distortion below -0.2% for highly controlled image geometry.
• 5MP resolution for detailed industrial imaging.
• Visible + 850nm dual-pass design for visible and near-infrared imaging.
• Compact M12 × 0.5 configuration with a 16.37mm TTL.

This lens is part of the M12 Lenses range and provides an unusual combination of wide-angle coverage and extremely low distortion. This makes it particularly valuable for compact vision systems where a broad viewing area is required without introducing significant geometric deformation.

M12 Low Distortion Wide Angle Lens Applications

Core Application Scenes

This 2.98mm M12 industrial lens is designed for applications requiring a wide field of view while maintaining much tighter geometric control than conventional wide-angle optics. On a 1/2.5″ sensor, it provides a 100° diagonal and 86.9° horizontal FOV, allowing a compact camera to capture a large scene without relying on an extremely distorted image.

Its most distinctive characteristic is the distortion below -0.2%. This specification makes the lens particularly suitable for vision systems where wide-area coverage and image geometry need to coexist. Examples include visual positioning, object detection, scene analysis, industrial monitoring, and embedded machine vision where straight edges and object proportions should remain relatively stable across the image.

The integrated visible and 850nm dual-pass filter gives this lens a specialized advantage for systems that need to operate in both visible-light and 850nm near-infrared imaging conditions. This can be useful in smart vision equipment where NIR illumination is used to enhance contrast, support imaging under controlled lighting, or capture information that is less visible under conventional illumination.

The compact M12 × 0.5 mount and 16.37mm TTL also make the lens practical for embedded camera modules and space-constrained vision devices. With a 0.2m minimum object distance, it can be integrated into relatively close-range imaging systems where a broad field of view is required.

The lens is not intended to replace a dedicated fisheye lens. Instead, its optical positioning is closer to a low-distortion wide-angle lens, making it particularly useful when the application needs broad coverage without the pronounced geometric deformation normally associated with extreme wide-angle imaging.

For engineers calculating the expected coverage at a particular installation distance, the FOV Calculator can be used to evaluate sensor size, focal length, and field-of-view relationships.

Designed for low-distortion wide-area imaging, embedded vision, and visible/850nm near-infrared machine vision applications.
