Wide Angle Lens – CCL118043MP

CCL118043MP-105° wide-angle CCTV lens,4.3mm F2.3 M12 mount lens, 1/1.8″ format, 6MP resolution, and IR correction

4.3mm 6MP M12 Wide Angle IR Corrected Lens

This 4.3mm 6MP M12 wide angle lens is designed for compact imaging systems that require a broad field of view, controlled distortion, and stable visible-to-infrared imaging. With a 1/1.8″ image format, 140° diagonal FOV, and IR-corrected optical design, it is well suited for embedded vision, compact surveillance, automotive vision, and other space-constrained camera systems.

Its fixed focal length, manual focus, fixed iris, and M12 mount provide a practical optical configuration for camera modules requiring wide scene coverage without a complex mechanical lens assembly.

Wide Angle Lens Core Highlights

• 140° Wide Field of View: Captures a broad scene with a 4.3mm focal length.
• 6MP High-Resolution Imaging: Supports detailed imaging for modern compact camera systems.
• IR-Corrected Optical Design: Helps maintain consistent imaging performance across visible and near-infrared wavelengths.
• M12 Mount Compatibility: Suitable for compact embedded camera modules and space-constrained optical assemblies.
• Controlled Wide-Angle Distortion: TV distortion below -14% provides better geometric control than many extreme wide-angle designs.

Wide Angle Lens Applications

Core Application Scenes

This 6MP M12 wide angle lens is designed for imaging systems where broad scene coverage is more important than long-distance magnification. Its 140° diagonal field of view allows a single compact camera to capture a large area, making it particularly useful for embedded cameras installed in confined spaces.

For compact smart surveillance, the lens can cover entrances, corridors, equipment areas, small rooms, and other scenes where cameras need a wide viewing angle while maintaining useful image detail. The 6MP resolution also provides sufficient image information for AI-assisted monitoring and object recognition.

The combination of wide-angle coverage and IR correction makes the lens suitable for 24-hour vision systems that operate under both visible and near-infrared illumination. It can be integrated into smart cameras, compact security modules, and embedded AI vision devices that require stable optical performance without a large lens assembly.

The lens can also support selected automotive and mobile vision applications, particularly where compact dimensions, wide coverage, and M12 mechanical integration are important. For systems requiring a broader understanding of automotive optical requirements, see the ADAS solution.

For industrial environments, the lens can be used in compact inspection or monitoring devices that need to observe a relatively large area from a short installation distance. It is especially useful where conventional industrial lenses would be too large or where a wide viewing angle is required.

A: This lens is suitable for compact wide-angle imaging applications such as smart surveillance, embedded AI cameras, industrial monitoring, selected automotive vision systems, and other camera modules requiring broad scene coverage.

Q: What sensor size is compatible with this M12 lens?

A: The lens is specified for a 1/1.8″ image format and provides a 140° diagonal, 105° horizontal, and 66° vertical field of view when paired with the IMX178 sensor.

Q: Is the 4.3mm M12 lens fixed focus or adjustable focus?

A: The lens uses manual focus. You may therefore adjust focus during camera assembly or optical calibration, with a fixed 4.3 mm focal length.

Q: How wide is the field of view of this lens?

A: With the IMX178 sensor, the lens provides a 140° diagonal FOV, 105° horizontal FOV, and 66° vertical FOV, making it a strong option for wide-area scene coverage.

Q: Does this lens have low distortion?

A: The specified TV distortion is below -14%. This offers controlled distortion for a wide‑angle optical design, though you should verify this lens against the exact geometric accuracy requirements of your application.

Q: Can this lens be customized for OEM camera projects?

A: M12 lenses can be adapted for different embedded camera designs and application requirements. For OEM or project-specific requirements, TOWIN can evaluate optical, mechanical, and integration requirements.

Q: How can I choose the correct lens for my camera sensor?

A: Sensor size, focal length, required FOV, resolution, distortion, and installation distance should be considered together. TOWIN’s Lens Selection Guide provides a practical starting point for choosing an appropriate industrial or embedded vision lens.
