Low Distortion Lens – CCL123030MPFR

CCL123030MPFR Low distortion wide angle M12 S-mount board lens 1/2.3″ 3mm F4.0 HD 5MP rectilinear scanning

3mm 5MP M12 Wide Angle Low Distortion Lens

This 3mm 5MP M12 lens is designed for compact imaging systems that require a wide field of view, close focusing capability, and controlled image distortion. With a 104° diagonal FOV on a 1/2.3″ sensor, this fixed focal lens provides broad scene coverage while maintaining image quality for space-constrained camera designs.

Product Core Highlights

• 5MP resolution for detailed compact-camera imaging
• 104° diagonal FOV for wide scene coverage
• 3mm fixed focal length for close-range wide-angle imaging
• < -1% distortion for controlled image geometry
• M12 × 0.5 mount for compact camera integration

Low Distortion Lens Applications

Wide-Angle Compact Security Cameras

This 3mm M12 lens is well suited to compact security cameras where a broad viewing area is more important than long-distance surveillance. The 104° diagonal field of view helps capture more of the surrounding scene from a relatively short installation distance, making it useful for indoor monitoring, entry areas, compact security modules, and space-limited camera housings.

Smart Doorbells and Indoor Monitoring Devices

The short 3mm focal length and 0.01m minimum object distance make this lens suitable for close-range imaging applications such as smart doorbells, indoor monitoring cameras, and compact IoT vision devices. The wide field of view can help capture people or objects positioned close to the camera without requiring a large optical assembly.

Compact Embedded Vision Systems

With an M12 × 0.5 mount and a 20.9mm total track length, the lens can be integrated into compact embedded camera modules where installation space is limited. The 5MP resolution provides sufficient detail for general-purpose visual monitoring, object observation, and scene awareness applications.

Suitable Devices

• Compact IP and IoT security cameras
• Smart video doorbells
• Indoor monitoring cameras
• Embedded vision camera modules
• Compact wide-angle imaging devices
• Space-constrained camera systems

Lens Selection Considerations

When integrating a wide-angle lens into a camera system, sensor format, field of view, focal length, and distortion should be evaluated together. This lens is optimized for a 1/2.3″ image format and provides a 104° diagonal FOV with a 3mm focal length. Engineers can use the Sensor Guide to better understand sensor and lens compatibility.

For applications where field of view needs to be calculated according to sensor size, working distance, and focal length, the FOV Calculator can help estimate the required optical configuration. The Lens Selection Guide also provides additional guidance for selecting an appropriate industrial or embedded camera lens.

Because this lens provides less than -1% distortion, it can be considered for applications where maintaining relatively controlled image geometry is important. For a deeper understanding of distortion specifications and their impact on imaging performance, see the Distortion Guide.

Frequently Asked Questions

Q: What sensor size is compatible with this M12 lens?
A: This lens is designed for a 1/2.3″ image format and provides its specified 104° diagonal, 92° horizontal, and 75° vertical field of view on a 1/2.3″ sensor.

Q: What is the field of view of this 3mm M12 lens?
A: The lens provides a 104° diagonal field of view, 92° horizontal field of view, and 75° vertical field of view when used with a 1/2.3″ sensor.

Q: Is this a fixed focal length lens?
A: Yes. The lens has a fixed 3mm focal length and a fixed F4.0 aperture, making it suitable for camera systems with a defined viewing area.

Q: Is this lens suitable for wide-angle imaging?
A: Yes. With a 104° diagonal FOV on a 1/2.3″ sensor, this lens is designed for wide-angle imaging where broad scene coverage is required in a compact camera system.

Q: What type of mount does this lens use?
A: The lens uses an M12 × 0.5 mount, a compact threaded interface commonly used in embedded camera modules and small-form-factor imaging systems.

Q: What is the minimum object distance of this lens?
A: The minimum object distance is 0.01m, or 10mm, making the lens suitable for certain close-range imaging applications.

Q: Is this lens a low distortion lens?
A: The specified distortion is less than -1%, providing controlled geometric distortion compared with conventional wide-angle designs. It can therefore be considered for applications where low distortion is an important selection criterion.

Q: Can TOWIN customize the lens for a specific camera system?
A: TOWIN can discuss optical requirements such as focal length, field of view, sensor format, mount, and other configuration requirements. Contact TOWIN to discuss your specific lens requirements.
