Low Distortion Lens – S06512504430F

S06512504430F is 5-Megapixel low distortion 1/2.5″ M12/S-Mount CCTV lens with built-in IR filter, 56°(D) F3.0 for machine vision and security surveillance.

6.5mm 5MP M12 Ultra Low Distortion Fixed Focal Lens

This 6.5mm 5MP M12 ultra low distortion lens is designed for compact imaging systems that require highly accurate image geometry and a controlled field of view. With distortion below -0.1%, it minimizes geometric deformation and is well suited to vision applications where image accuracy is more important than extremely wide scene coverage.

Featuring a 1/2.5″ image format, M12×0.5 mount, F3.0 fixed aperture, 0.2m minimum object distance, and an ultra-compact Φ14 × 9.1mm housing, this fixed focal lens is ideal for miniature embedded cameras, compact inspection modules, smart visual sensing devices, and space-constrained OEM camera designs.

6.5mm M12 Low Distortion Lens Applications

Core Application Scenes

This 6.5mm M12 ultra low distortion lens is specifically designed for compact imaging systems where geometric accuracy is a key optical requirement. With distortion below -0.1%, the lens provides exceptionally controlled image geometry, making it suitable for applications where significant barrel or pincushion deformation could interfere with image interpretation.

The 44° horizontal FOV provides a focused view of the target area, making this lens particularly appropriate for compact inspection cameras, dimensional observation systems, smart access devices, embedded visual sensors, and equipment monitoring modules. Rather than prioritizing maximum scene coverage, the optical design is better suited to applications that need a stable representation of a defined target area.

Its strongest mechanical advantage is the extremely compact Φ14 × 9.1mm form factor and 10.6mm TTL. This allows the lens to fit into miniature camera housings and embedded devices where conventional optics may consume too much internal space. The 1.5mm M.B.F.L. further supports compact optical-mechanical integration.

The 0.2m minimum object distance allows the lens to be used for relatively close-range imaging, making it suitable for cameras mounted near equipment, control interfaces, inspection targets, or access points.

For applications where image geometry is critical, engineers can refer to Towin’s Distortion Guide to understand how lens distortion affects imaging performance. The Optical Design section also provides additional information for evaluating optical characteristics during system development.

Frequently Asked Questions

Q: What type of lens is this 6.5mm M12 lens?
A: It is a fixed focal, ultra low distortion M12 lens designed for 1/2.5″ sensors and 5MP imaging. Its distortion is specified below -0.1%.

Q: What makes this lens a low distortion lens?
A: The specified distortion is below -0.1%, which indicates exceptionally controlled geometric deformation. This characteristic makes the lens suitable for imaging systems where image geometry is important.

Q: Is this 6.5mm M12 lens a wide-angle lens?
A: No. Its 56° diagonal FOV and 44° horizontal FOV provide moderate scene coverage. It is better positioned as a focused, low-distortion lens rather than a dedicated wide-angle lens.

Q: What sensor format does this lens support?
A: The specified image format is 1/2.5″, and the lens is rated for 5MP resolution.

Q: What is the field of view of the 6.5mm lens?
A: The lens provides a 56° diagonal FOV, 44° horizontal FOV, and 35° vertical FOV.

Q: What is the advantage of the Φ14 × 9.1mm compact design?
A: The small housing diameter and short overall height allow the lens to be integrated into miniature camera modules where installation space is limited.

Q: What does the IRCF specification mean?
A: IRCF indicates that the optical assembly includes an IR-cut filter. It should not automatically be interpreted as an IR-corrected optical design.

Q: What is the minimum object distance of this M12 lens?
A: The specified minimum object distance is 0.2m, allowing the lens to image relatively close subjects when properly integrated and focused.
