Low Distortion Lens – S03412308725

S03412308725 is 3.4mm M12 16MP wide angle lens with 99° FOV and <1% distortion for machine vision, industrial inspection, robotics and security.

3.4mm M12 16MP Low Distortion Lens

This 3.4mm M12 lens is a high-resolution wide angle lens designed for compact industrial and machine vision cameras. With a 16MP resolution, 99° diagonal FOV, and TV distortion below 1%, it delivers a broad viewing area while maintaining excellent image geometry for applications where both coverage and image accuracy are important.

Featuring an M12×0.5 mount, F2.8 fixed aperture, 0.1m minimum object distance, and 5G2M optical construction, this compact lens is well suited for high-resolution embedded vision systems, inspection cameras, robotics, smart security, and other space-constrained imaging devices.

M12 Low Distortion Lens Core Highlights

• 16MP High-Resolution Imaging: Supports detailed image capture for demanding machine vision and industrial imaging applications.
• 99° Wide Field of View: The 3.4mm focal length provides broad scene coverage without requiring an extremely short focal length.
• Ultra-Low Distortion: TV distortion below 1% helps preserve straight lines and object geometry across the image.
• Compact M12×0.5 Mount: The M12 mount simplifies integration into compact cameras, embedded vision modules, and space-limited optical systems.
• Close-Focus Capability: A 0.1m M.O.D. supports imaging of relatively close objects in inspection and monitoring applications.

M12 Low Distortion Lens Applications

Core Application Scenes

This M12 wide angle lens combines a broad 99° diagonal FOV with less than 1% TV distortion, making it suitable for imaging systems that need both wide scene coverage and accurate image geometry. Compared with conventional fisheye lenses, its low-distortion optical design is better suited to applications where excessive image deformation could affect visual inspection or image analysis.

Designed for compact high-resolution machine vision applications.

Typical applications include:

• Compact machine vision cameras
• Industrial inspection systems
• Robotics vision
• Embedded inspection equipment
• Smart security cameras
• Factory monitoring systems
• Automated visual inspection
• Wide-area object detection
• High-resolution industrial imaging
• Intelligent camera modules

For automated inspection and robotic imaging projects, this lens can be integrated with TOWIN’s Machine Vision Solutions and Robotics Vision Solutions.

Compatible Device List

The M12×0.5 mount and compact optical configuration make this lens suitable for:

• 16MP industrial cameras
• IMX377-based camera modules
• Embedded machine vision cameras
• Compact inspection cameras
• Robotic vision cameras
• Smart security cameras
• Industrial monitoring cameras
• Fixed-mount imaging modules
• OEM camera systems

When selecting an M12 lens for a specific camera sensor, the image format, sensor dimensions, focal length, FOV, and image circle should be checked together. TOWIN’s Sensor Guide can help determine whether the lens provides appropriate sensor coverage.

Optical Design Considerations

The combination of a 3.4mm focal length, 85° horizontal FOV, and <1% TV distortion provides a useful balance between coverage and geometric accuracy. This makes the lens particularly attractive when a system needs a wider field of view than a standard lens but cannot tolerate the severe geometric deformation normally associated with fisheye optics.

The maximum image format is Φ8.8, so the lens should be matched with the actual sensor format and active imaging area during system design. For applications requiring precise field-of-view calculations, use the FOV Calculator to evaluate the relationship between focal length, sensor size, and object distance.

Frequently Asked Questions

Q: What type of lens is this 3.4mm M12 lens?
A: It is a 16MP M12 wide angle lens with a fixed 3.4mm focal length, 99° diagonal FOV, and TV distortion below 1%. It is suitable for machine vision, industrial imaging, security, and embedded camera applications.

Q: Is this lens a fisheye lens?
A: No. Although the lens provides a relatively wide 99° diagonal FOV, its TV distortion is below 1%, making it a low-distortion wide angle lens rather than a conventional fisheye lens.

Q: Why is less than 1% distortion important for machine vision?
A: Low distortion helps preserve the shape and relative position of objects in the image. This is especially useful for inspection, measurement support, object recognition, and machine vision systems where excessive image deformation can reduce image-analysis accuracy.

Q: What applications are suitable for this 16MP M12 lens?
A: It is suitable for compact machine vision cameras, industrial inspection, robotics vision, embedded imaging, smart security, factory monitoring, and other applications requiring high resolution and wide scene coverage.

Q: What is the minimum object distance of this lens?
A: The M.O.D. is 0.1m, allowing the lens to focus on objects from relatively short distances. This makes it useful for close-range inspection and compact imaging equipment.

Q: Does the lens use a fixed or adjustable iris?
A: The lens uses a fixed F2.8 aperture. A fixed iris provides a consistent optical configuration and simplifies integration into compact camera systems.

Q: Can TOWIN customize this M12 lens for an OEM project?
A: TOWIN can support customized optical solutions according to project requirements such as sensor format, focal length, FOV, distortion, mount, mechanical dimensions, and other optical specifications. For OEM or ODM requirements, contact the TOWIN engineering team.
