• 3.4mm focal length with 86° diagonal FOV provides broad scene coverage without the extreme distortion of fisheye optics.
• 850nm band-pass filter is suitable for imaging systems designed around near-infrared illumination at approximately 850nm.
• M12 × 0.5 fixed-focus design enables integration into compact embedded and machine vision camera modules.

3.4mm M12 Low Distortion Lens Applications

Core Application Scenes

This lens combines an 8MP optical system with very low distortion and an 850nm band-pass filter. The combination is particularly relevant to imaging systems that use controlled near-infrared illumination rather than relying exclusively on visible-light imaging.

Designed for NIR machine vision and compact inspection application.

Typical applications include:

• NIR Machine Vision: The 850nm band-pass filter can be used in systems employing 850nm illumination to isolate the desired near-infrared imaging band.
• Industrial Inspection: The <0.4% distortion specification helps maintain consistent image geometry when inspecting components or structures.
• High-Resolution Embedded Vision: The 8MP optical specification is suitable for compact camera modules requiring detailed image capture.
• AI Vision: The combination of 8MP resolution and controlled distortion can support image acquisition for object recognition, classification, and visual analysis.
• Robotics Vision: The 78° horizontal FOV provides a useful balance between scene coverage and controlled perspective for compact robotic vision systems.
• Security and Recognition Imaging: The 850nm optical filtering can be integrated into systems using dedicated NIR illumination for recognition or monitoring.
• OEM Imaging Systems: The compact M12 interface allows the lens to be incorporated into customized camera assemblies and embedded imaging equipment.

For applications where sensor format, focal length, and field of view need to be matched, the Sensor Guide and FOV Calculator can help with optical selection.

8MP IMX415 Optical Performance

The lens is specifically specified for the 1/2.8″ IMX415 sensor, providing an 86° diagonal, 78° horizontal, and 50° vertical field of view.

The 8MP resolution makes it suitable for applications where image detail is important, while the <0.4% TV distortion helps preserve image geometry across the captured scene.

This is particularly useful when a camera must combine relatively broad scene coverage with controlled geometric distortion. Unlike a fisheye lens, this design does not rely on extreme optical distortion to achieve its field of view.

For more information about distortion and how it affects industrial imaging, refer to the Distortion Guide.

850nm Band-Pass Filter for NIR Imaging

A key feature of this lens is its 850BPF, indicating an 850nm band-pass filter configuration.

This optical filtering approach is useful in systems where an 850nm NIR light source is deliberately used to illuminate the target. Engineers can pick a suitable optical band and design the camera system for a defined NIR imaging wavelength rather than standard visible‑light imaging.

Potential applications include:

• NIR machine vision
• Pattern recognition
• Controlled-light inspection
• AI vision systems
• NIR object detection
• Embedded recognition cameras
• Specialized OEM imaging systems

The 850BPF specification should not be interpreted as an IR-corrected optical design. Band-pass filtering and infrared optical correction serve different functions: the filter selects a wavelength range, while IR correction addresses focal shift and image quality across different wavelengths.

Compact M12 Camera Integration

The M12 × 0.5 mount is widely suited to compact camera modules and embedded imaging equipment. With a total optical length of 14.44mm and a 0.2m minimum object distance, this lens can be incorporated into relatively compact camera assemblies.

The F2.2 fixed aperture provides a stable optical configuration for controlled imaging systems, while the 1G4P + 850BPF construction combines the optical elements with the specified NIR filtering function.

Low Distortion Imaging for Machine Vision

With TV distortion below 0.4%, this lens is particularly suitable for applications where straight-line reproduction and geometric consistency are important.

Low distortion can be beneficial in:

• Dimensional inspection
• Object positioning
• Feature recognition
• Machine vision measurement
• Robotic guidance
• AI image analysis
• Industrial monitoring

When selecting a lens for a specific working distance and target size, the Lens Selection Guide can help determine whether the focal length and field of view meet the application requirements.

Frequently Asked Questions

Q: What sensor is this 3.4mm M12 lens designed for?
A: The lens is specified for the 1/2.8″ Sony IMX415 sensor and provides an 86° diagonal, 78° horizontal, and 50° vertical field of view.

Q: What is the resolution of this M12 lens?
A: The lens is specified at 8MP resolution and is designed for high-resolution imaging applications using compatible 1/2.8″ sensors.

Q: Is this lens a fisheye lens?
A: No. Although the lens provides an 86° diagonal FOV, its TV distortion is less than 0.4%, which is characteristic of a controlled low-distortion design rather than fisheye optics.

Q: What does the 850BPF specification mean?
A: 850BPF indicates an 850nm band-pass filter. It is intended for imaging systems using a controlled near-infrared wavelength around 850nm.

Q: Is the 850BPF the same as an IR corrected lens?
A: No. An 850nm band-pass filter selects a specific wavelength range, while IR correction is an optical design feature intended to control focus and image quality for infrared wavelengths. Therefore, this product is not classified as an IR Corrected Lens based solely on the 850BPF specification.

Q: What is the distortion specification?
A: The specified TV distortion is less than 0.4%, providing low-distortion imaging for applications where geometric consistency is important.

Q: What is the minimum object distance?
A: The M.O.D. is 0.2m, making the lens suitable for relatively close-range inspection and embedded imaging applications.

Q: What type of camera can use this lens?
A: The M12 × 0.5 mount is suitable for compatible IMX415-based industrial cameras, embedded vision modules, NIR cameras, AI cameras, robotic vision systems, and customized OEM camera assemblies.
