IR Corrected Lens – S06012505812

S06012505812 is a F1.2 low light M12 IR corrected CCTV lens.  It is a 6mm HD 3 Megapixel S-mount board lens for 1/2.5″ IMX317, MT9P031. It has a large aperture for IP security surveillance camera.

Product Overview

This 6mm M12 IR corrected CCTV lens is designed for compact imaging systems that require a balance of wide-angle coverage, high light transmission, and reliable infrared imaging. Featuring a 1/2.5″ image format, 3MP resolution, 75° diagonal F.O.V., and a fast F1.2 aperture, the lens provides broad scene coverage while delivering strong light-gathering capability for challenging illumination conditions. Its 20% distortion is suited to wide-angle monitoring applications where coverage is prioritized over precision geometric reproduction. The M12x0.5 mount supports integration into compact board cameras, while the 0.3m minimum object distance provides useful close-to-medium range imaging capability. Designed for low-light security and IR imaging applications, this lens is suitable for CCTV surveillance, smart security, intelligent traffic monitoring, and embedded vision systems operating under both visible and near-infrared illumination.

M12 IR Corrected CCTV Lens Advantages

Fast F1.2 Aperture
The F1.2 aperture provides high light-gathering capability, making this lens particularly suitable for low-light surveillance and imaging environments where maintaining image brightness is important.

75° Wide-Angle Coverage
The 75° diagonal field of view provides broad scene coverage while offering a more moderate perspective than extreme ultra-wide-angle lenses.

3MP Resolution
The 3MP optical configuration provides sufficient image detail for a wide range of surveillance, monitoring, and embedded camera applications.

IR-Corrected Optical Design
The IR-corrected configuration helps reduce focus shifts between visible and near-infrared wavelengths, supporting cameras that operate across different lighting conditions.

Compact M12x0.5 Mount
The M12 mount provides a compact and widely used interface for board cameras and embedded imaging modules.

Wide-Angle 6mm Focal Length
The 6mm focal length offers a useful balance between scene coverage and object representation, making it suitable for security and intelligent monitoring applications.

Close-Focus Capability
With a 0.3m M.O.D., the lens can support relatively close subjects while maintaining the specified optical performance.

M12 IR Corrected CCTV Lens Applications

CCTV & Security Cameras
The combination of F1.2 aperture, 75° FOV, and 3MP resolution makes this lens suitable for surveillance cameras requiring broad coverage and strong low-light performance.

Smart Traffic Monitoring
The 6mm focal length and 75° FOV can provide useful scene coverage for traffic monitoring and intelligent transportation cameras, while IR correction supports systems that use infrared illumination.

See TOWIN’s Smart Traffic Solutions.

Embedded Vision Systems
The compact M12x0.5 interface allows integration into embedded camera modules used in monitoring, intelligent devices, and compact vision platforms.

Night and Low-Light Imaging
The F1.2 aperture provides strong light transmission, while IR correction supports more consistent focus when near-infrared illumination is introduced. This combination is valuable for cameras operating during nighttime or in poorly illuminated environments.

Lens Selection & Technical Considerations

Focal Length and Field of View
The 6mm focal length provides a 75° diagonal FOV, with the supplied specification also listing 58° and 42° viewing angles. This configuration provides a relatively broad perspective while retaining more object separation than very short focal length M12 lenses.

For evaluating FOV according to your sensor and focal length, use TOWIN’s FOV Calculator.

IR-Corrected Performance
The IR-corrected optical design helps compensate for wavelength-dependent focus variation between visible light and near-infrared wavelengths. This makes the lens suitable for day/night camera systems and applications using IR illumination.

For projects requiring specific infrared wavelengths, the final optical configuration should be evaluated against the camera sensor and illumination source.

Low-Light Performance
The F1.2 aperture is one of the key strengths of this lens. A larger aperture allows more light to reach the camera sensor, which can help maintain image brightness and detail in low-light conditions. Actual performance will also depend on sensor sensitivity, exposure settings, illumination, and image processing.

Distortion Consideration
The specified distortion is 20%. This level is suitable for many wide-angle surveillance and monitoring applications where broad coverage is more important than highly accurate geometric reproduction. For measurement-oriented applications, a dedicated low-distortion lens may be more appropriate.

See TOWIN’s Distortion Guide for more information.

Sensor Compatibility
The M12 IR corrected CCTV lens is designed for a 1/2.5″ image format and supports 3MP resolution. Matching the lens image format with the camera sensor helps ensure proper image coverage and avoid vignetting.

Mechanical Integration
The M12x0.5 mount and 36.8mm T.T.L. should be considered when designing the camera housing and optical assembly. The actual sensor position, mechanical clearance, and focus adjustment should be verified during system integration.

For broader optical selection considerations, see the Lens Selection Guide.

Frequently Asked Questions

Q: What applications is this 6mm M12 IR corrected CCTV lens suitable for?
A: This lens is suitable for CCTV surveillance, smart security, smart traffic monitoring, low-light imaging, embedded vision, and day/night camera systems requiring a fast F1.2 aperture and IR-corrected optical performance.

Q: What is the field of view of this M12 lens?
A: The supplied specification lists a 75° field of view, along with 58° and 42° viewing angles. The exact diagonal, horizontal, and vertical FOV should be confirmed according to the camera sensor and active imaging area.

Q: Why is the F1.2 aperture important?
A: The F1.2 aperture provides strong light-gathering capability, helping cameras maintain image brightness in low-light environments. This makes the lens particularly useful for surveillance and nighttime imaging.

Q: Is this a low-distortion M12 lens?
A: The specified distortion is 20%, so this lens qualifies as a wide‑angle lens, not a precision low‑distortion lens. It is better suited for surveillance applications prioritizing broad coverage.

Q: What sensor size is this lens designed for?
A: The lens is designed for a 1/2.5″ image format and supports 3MP resolution. The camera sensor should be checked against the lens image format before final integration.

Q: What is the minimum object distance?
A: The M.O.D. is 0.3m, allowing the lens to focus on subjects at relatively close distances. The practical working distance should be evaluated based on the required object size and camera configuration.

Q: Can TOWIN customize this IR-corrected M12 lens?
A: Yes. TOWIN supports OEM and ODM optical development for customized imaging systems. Focal length, FOV, sensor format, distortion, infrared performance, mechanical dimensions, and other optical requirements can be evaluated according to the project. Contact TOWIN for engineering support.
