3.3mm 3MP M12 Wide Angle Lens for OV2710 and AR0330

This 3.3mm 3MP M12 wide angle lens is designed for compact camera modules using 1/2.7″ and 1/3″ image sensors, providing flexible integration across different embedded imaging platforms. It supports the 1/2.7″ OV2710 with a 137° diagonal field of view and the 1/3″ AR0330 with a 121° diagonal field of view.

With a 3.3mm focal length, F2.0 fixed aperture, M12×0.5 mount, and 0.2m minimum object distance, the lens is designed for applications that require broad scene coverage from a compact optical assembly. Its 3MP resolution provides a practical balance between image detail, camera size, and system requirements.

The lens is well suited to embedded vision, smart security, robotics, industrial monitoring, and other compact imaging systems. It can be evaluated alongside TOWIN’s M12 Lenses for projects requiring different focal lengths, sensor formats, and viewing angles.

M12 Wide Angle Lens Applications

Core Application Scenes

The combination of 3.3mm focal length, wide field of view, dual sensor compatibility, and compact M12 mounting makes this lens suitable for camera systems where broad coverage and flexible sensor integration are important.

Typical applications include:

• Embedded machine vision
• Smart security cameras
• Indoor surveillance
• Robotics and mobile robots
• Industrial equipment monitoring
• Compact inspection systems
• Presence and object detection
• IoT vision devices
• Edge-AI camera modules
• Short-range monitoring systems
• Wide-area indoor imaging

Designed for flexible wide-angle embedded vision applications, this lens is particularly useful for OEM camera designs that may use either a 1/2.7″ or 1/3″ sensor platform.

For application-specific optical integration, it can also be considered for TOWIN’s Machine Vision, Robotics Vision, and Smart Security solutions.

Compatible Device Types

This M12 wide angle lens can be integrated into:

• OV2710 camera modules
• AR0330 camera modules
• 1/2.7″ CMOS camera systems
• 1/3″ CMOS camera systems
• Compact IP cameras
• Embedded vision cameras
• Robotics vision modules
• Industrial monitoring cameras
• Smart security devices
• Edge-AI imaging equipment
• Compact machine vision systems

The M12×0.5 interface allows the lens to be incorporated into compact optical housings and customized camera assemblies where installation space is limited.

Dual-Sensor Compatibility

A key feature of this lens is its support for two different sensor formats. When paired with the 1/2.7″ OV2710, the lens provides a 137° diagonal, 113° horizontal, and 58° vertical FOV. With the 1/3″ AR0330, the field of view changes to 121° diagonal, 96° horizontal, and 61° vertical.

This difference illustrates why sensor size should be considered together with focal length when selecting a wide-angle lens. Even with the same 3.3mm focal length, changing the sensor format changes the effective image coverage.

For engineers comparing sensor and lens combinations, TOWIN’s Sensor Guide provides additional reference information for sensor-format selection.

Wide Angle Optical Design

The 3.3mm focal length provides broad scene coverage, particularly with the 1/2.7″ OV2710 configuration. This makes the lens suitable for applications where the camera needs to monitor a relatively large area without increasing the physical distance between the camera and the subject.

The specified distortion of less than -39% reflects the optical trade-off associated with the wide field of view. This lens should therefore be selected primarily when broad coverage is more important than highly accurate geometric reproduction.

For applications where distortion is a key design parameter, engineers can use TOWIN’s Distortion Guide when comparing different wide-angle optical solutions.

The F2.0 fixed aperture provides a practical balance between light-gathering capability, optical dimensions, and imaging stability for compact camera systems.

Mechanical Integration

The lens uses an M12×0.5 mount with a specified 5.57mm back focal length and 22mm total track length. These dimensions are important when designing the camera housing and determining the available mechanical space around the sensor and lens assembly.

The 0.2m minimum object distance also gives camera designers flexibility for short-range imaging applications where the camera cannot be positioned far away from the target.

For preliminary lens selection, TOWIN’s Lens Selection Guide can help engineers evaluate focal length, sensor format, field of view, and application requirements together.

Related Optical Resources

Choosing between different M12 lenses requires evaluating the sensor format, focal length, required field of view, distortion, and installation distance together. TOWIN’s Lens Basics provides fundamental information about these optical parameters.

For projects where the required image coverage is already known, the FOV Calculator can be used to estimate the relationship between sensor size, focal length, and field of view.

The Focal Length Calculator is also useful during preliminary lens selection when engineers need to identify an appropriate focal length for a target imaging area.
