Wide Angle Lens – CCL127031MP

CCL127031MP 3.1mm 2MP M12 wide angle lens for 1/2.7″ OV2710 sensors

3.1mm 2MP M12 Wide Angle Lens for 1/2.7″ Sensors

This 3.1mm M12 wide angle lens is designed for compact camera modules that require an exceptionally broad field of view in a small optical package. With a 133° diagonal FOV, 111° horizontal FOV and 60° vertical FOV on the OV2710 sensor, the lens captures a large viewing area while maintaining a compact 22.34mm TTL. Its M12×0.5 mount, fixed 3.1mm focal length and manual focus make it suitable for embedded cameras and space-constrained imaging equipment.

The lens supports 2MP resolution at 1920×1080 and uses an F1.6 aperture to provide a relatively large amount of light for wide-angle imaging. Its 2G5P optical construction balances compactness with practical imaging performance, while the fixed iris and fixed focal configuration provide a straightforward optical solution for camera manufacturers. As part of TOWIN’s M12 lenses, it can be considered for applications where wide coverage and compact mechanical integration are more important than ultra-low geometric distortion.

Key Product Highlights

Ultra-Wide 133° Diagonal Field of View

• 133° diagonal FOV and 111° horizontal FOV provide broad scene coverage from a short 3.1mm focal length.
• The wide viewing angle helps reduce blind areas when the camera must monitor a large scene from a relatively short distance.
• It is particularly useful for compact camera designs where moving the camera farther away from the target is not practical.

F1.6 Aperture for Wide-Angle Imaging

• The F1.6 aperture provides a relatively bright optical path for a compact wide-angle lens.
• A wider aperture can help maintain usable image brightness when ambient illumination is limited.
• This makes the lens more suitable for embedded cameras that need wide coverage without relying entirely on strong external lighting.

Compact M12×0.5 Mount

• The M12×0.5 mount supports integration into compact camera modules and space-constrained optical assemblies.
• The 22.34mm TTL helps reduce the overall optical footprint compared with larger industrial lens configurations.
• For additional M12 optical options, TOWIN’s S-Mount Lenses portfolio provides different focal lengths and application-oriented lens configurations.

2MP Full HD Imaging

• The lens supports 2MP resolution at 1920×1080, matching the requirements of Full HD imaging systems.
• The OV2710 sensor format provides a defined optical reference for evaluating the lens and camera combination.
• This makes the model appropriate for applications where broad scene coverage and Full HD image output are required rather than high-megapixel inspection.

Fixed-Focal Configuration for Simple Integration

• The 3.1mm fixed focal length, fixed iris and manual focus configuration simplify the optical architecture.
• A fixed-focal design avoids the mechanical complexity associated with zoom or varifocal mechanisms.
• Camera manufacturers can use the fixed configuration when the installation distance and required viewing area are known in advance.

M12 Wide Angle Lens Applications

This 3.1mm M12 wide angle lens is best suited to compact imaging systems that prioritize broad scene coverage, small installation space and straightforward camera integration. Its 111° horizontal FOV makes it particularly useful where a conventional narrow-angle lens would leave excessive blind areas.

Core Applications

• Compact surveillance cameras — The wide horizontal FOV can cover a large area from a relatively close mounting position, making the lens suitable for small indoor monitoring cameras and embedded security modules.
• Smart home and IoT cameras — The compact M12×0.5 interface and 22.34mm TTL support integration into small camera housings where optical space is limited.
• Doorway and entrance monitoring — The wide viewing angle helps capture people approaching or passing through a doorway without requiring an excessively distant camera position.
• Embedded wide-angle cameras — The fixed 3.1mm focal length provides a predictable viewing geometry for camera modules designed around a predefined installation position.
• Compact monitoring devices — The combination of F1.6 aperture, 2MP resolution and ultra-wide FOV can support Full HD monitoring equipment where broad coverage is the primary requirement.

Compatible Devices

• 1/2.7″ OV2710-based camera modules
• 2MP / 1920×1080 embedded cameras
• M12×0.5 camera modules
• Compact surveillance cameras
• Smart home and IoT imaging devices
• Indoor monitoring cameras
• Space-constrained wide-angle camera assemblies

Because this lens has less than -14% TV distortion, it should be selected for applications where very wide coverage is more important than highly accurate geometric reproduction. For applications requiring precise dimensional imaging, customers should consider a dedicated Low Distortion Lens instead.

When selecting the lens for a specific sensor and installation distance, the required field of view can be evaluated with TOWIN’s FOV Calculator, while the Sensor Guide can help verify sensor and optical format compatibility.

Designed for compact wide-angle camera and embedded imaging applications.

Frequently Asked Questions

Q: What sensor size is this M12 lens designed for?
A: This lens is specified for a 1/2.7″ image format and is listed with the OV2710 sensor as the reference sensor.

Q: What is the field of view of the 3.1mm lens?
A: The lens provides a 133° diagonal FOV, 111° horizontal FOV and 60° vertical FOV on the specified OV2710 configuration.

Q: Is this a fixed focal length lens?
A: Yes. It has a 3.1mm fixed focal length and fixed zoom configuration, making it suitable for camera systems with a predefined viewing distance and coverage requirement.

Q: Does this lens have low distortion?
A: No. The specified TV distortion is less than -14%, so this model should not be classified as a low-distortion lens. It is better suited to applications where very wide coverage is more important than precise geometric accuracy.

Q: What type of mount does this lens use?
A: The lens uses an M12×0.5 mount, making it compatible with camera modules designed around the standard M12/S-Mount interface.

Q: Can the focus be adjusted?
A: Yes. The lens uses a manual focus configuration, allowing the focus position to be adjusted during camera module assembly or installation.

Q: Can TOWIN provide a different lens configuration for my camera module?
A: TOWIN can evaluate optical requirements such as sensor format, focal length, FOV, distortion, mounting interface and mechanical dimensions to determine whether an alternative or customized lens configuration is appropriate. Customers can contact TOWIN with their camera specifications for an optical solution assessment.
