3.4mm M9 Wide Angle Lens Applications

Core Application Scenes

This compact wide-angle lens is designed for applications that require a broad viewing area without the extreme geometric distortion normally associated with fisheye optics. Its 3.4mm focal length and 94° diagonal FOV make it suitable for capturing a relatively large scene from a short installation distance.

Designed for compact machine vision application.

Typical applications include:

• Compact Machine Vision: Suitable for inspection equipment where camera space is limited but a wide viewing area is required.
• Embedded Vision Systems: The M9 × 0.25 mount and compact optical format make it suitable for integrated camera modules.
• Robotics Vision: The 94° diagonal FOV can help compact robotic vision systems observe a wider working area at relatively short distances.
• Equipment Monitoring: The wide field of view can cover larger portions of machinery, instruments, or enclosed equipment from a constrained mounting position.
• AI Vision Cameras: Suitable for embedded AI cameras requiring 5MP image capture and controlled geometric distortion.
• Industrial Automation: Can be integrated into compact inspection and monitoring devices where installation space and viewing coverage are important considerations.

For systems where sensor size and viewing coverage need to be checked before lens selection, the Sensor Guide and FOV Calculator can help evaluate compatibility.

Why Choose a 3.4mm Wide Angle Low Distortion Lens?

A conventional wide-angle lens can introduce significant barrel distortion as the field of view increases. This 3.4mm lens combines a broad 94° diagonal FOV with <1% TV distortion, making it more appropriate for applications that need wide coverage while still maintaining relatively accurate image geometry.

The F2.0 aperture also provides a practical optical configuration for embedded cameras operating under varying illumination conditions. When selecting a lens based on working distance, sensor size, and required field of view, the Lens Selection Guide can be used as a reference.

The 0.2m minimum object distance further supports relatively close-range imaging, while the 1.49mm M.B.F.L. helps accommodate compact camera module designs.

Frequently Asked Questions

Q: What sensor size is this 3.4mm lens designed for?
A: The specified FOV is based on a 1/2.5″ sensor, with a 94° diagonal, 81° horizontal, and 65° vertical field of view.

Q: Is this 3.4mm M9 lens a fisheye lens?
A: No. Although it provides a wide 94° diagonal FOV, its TV distortion is specified at less than 1%, making it a wide-angle low-distortion lens rather than a fisheye lens.

Q: What is the resolution of this lens?
A: The lens supports 5MP resolution, making it suitable for compact machine vision, embedded vision, and industrial imaging applications.

Q: What does the F2.0 aperture mean for this lens?
A: The F2.0 aperture provides a relatively large optical opening for light transmission, which can be useful in machine vision and embedded imaging environments where illumination conditions vary.

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

Q: What type of camera uses this lens?
A: The M9 × 0.25 mount is suitable for compact industrial cameras, embedded vision modules, robotic camera systems, AI vision devices, and other space-constrained imaging equipment.

Q: What is the advantage of the <1% distortion specification?
A: Low distortion helps preserve the relative geometric position of objects in the image and can be beneficial for inspection, measurement, recognition, and other vision applications where image geometry matters.

Q: How can I determine whether this lens provides enough coverage for my application?
A: You can compare the 3.4mm focal length, 1/2.5″ sensor size, and required working distance using the FOV Calculator before selecting the lens.
