3.9mm M12 Wide Angle Lens Applications

Ultra-Wide Embedded Imaging

The 149° diagonal field of view allows this lens to capture a very large scene from a compact camera module. It is suitable for systems where maximizing visual coverage is more important than maintaining low geometric distortion.

Potential applications include:

• Compact embedded cameras
• Wide-area monitoring modules
• Robotics vision
• Mobile imaging systems
• Smart devices
• Compact industrial vision modules

The combination of an 8MP image capability and 1/1.7″ image format also makes the lens suitable for higher-resolution camera platforms requiring broad scene coverage.

For robotics-related applications, see TOWIN’s Robotics Vision solution.

Robotics and Mobile Vision

The extremely wide FOV can help mobile vision systems observe a large surrounding area without requiring multiple camera modules.

Potential uses include:

• Mobile robot perception
• Autonomous mobile platforms
• Navigation cameras
• Obstacle awareness systems
• Service robots
• Compact robotic vision modules

For broader machine vision applications, the Machine Vision solution provides additional information about optical configurations for industrial imaging.

Wide-Area Monitoring

The 123° horizontal FOV is particularly useful where horizontal scene coverage is important. A single camera can monitor a substantially larger area compared with conventional narrow-angle lenses.

Suitable systems may include:

• Wide-area monitoring cameras
• Smart security devices
• Indoor panoramic-style imaging systems
• Building monitoring equipment
• Compact surveillance modules
• Smart infrastructure cameras

For security applications, the Smart Security solution can be used as a reference when evaluating camera and lens configurations.

High-Resolution Wide-Angle Imaging

With an 8MP resolution specification and 1/1.7″ image format, this lens is designed for camera systems that need both high-resolution capture and extensive scene coverage.

The F1.8 aperture can provide useful light-gathering performance, while the fixed focal length keeps the optical configuration simple and consistent.

When matching this lens to a particular sensor, the Sensor Guide can help evaluate sensor format and image-circle compatibility.

Designed for ultra-wide embedded imaging, robotics vision, wide-area monitoring, and high-resolution camera applications requiring extensive scene coverage from a compact M12 lens.

Optical Design Considerations

This lens has a specified distortion of less than -66%, which is characteristic of an extremely wide-angle optical configuration. The strong distortion should therefore be considered when the application requires geometric accuracy or image processing.

For applications where straight-line preservation is important, a low-distortion optical configuration may be more appropriate. TOWIN’s Lens Selection Guide provides additional guidance on selecting focal length and optical characteristics according to application requirements.

The IRCF included in the 4G3MG + IRCF structure refers to an IR Cut Filter. It should not be interpreted as an IR-corrected lens design.

Frequently Asked Questions

Q1: What type of lens is the 3.9mm M12 lens?
A: It is a fixed-focal, ultra-wide-angle M12 lens designed for 1/1.7″ sensors and high-resolution imaging applications.

Q2: What is the field of view of this 3.9mm lens?
A: With the OX08B40 sensor, the specified FOV is 149° diagonal, 123° horizontal, and 66° vertical.

Q3: Is this lens suitable for 8MP cameras?
A: Yes. The lens is specified with an 8 Megapixel resolution and is designed around a 1/1.7″ image format.

Q4: Is the 3.9mm lens a fisheye lens?
A: It is positioned as a wide-angle lens. Although it provides a very wide 149° diagonal FOV and strong distortion, the product classification here is Wide Angle Lens rather than Fisheye Lens.

Q5: What does the F1.8 aperture provide?
A: The F1.8 aperture provides relatively strong light-gathering capability, which can be useful for wide-angle imaging in changing lighting conditions.

Q6: What mount does this lens use?
A: The lens uses an M12x0.5 mount, making it compatible with many compact embedded camera and M12 camera module designs.

Q7: Does IRCF mean this lens is IR corrected?
A: No. IRCF means an IR Cut Filter is included. An IR-corrected lens is a different optical design intended to compensate for wavelength-dependent focus shifts.

Q8: What applications are suitable for this ultra-wide-angle lens?
A: Typical applications include robotics vision, mobile imaging, wide-area monitoring, embedded cameras, smart security, and other systems requiring very broad scene coverage.
