4.0mm M12 8MP Wide Angle Lens Applications

Automotive Camera Systems

The combination of a 4.0mm focal length, 107° diagonal FOV, 8MP resolution, and IP67 protection makes this lens suitable for compact automotive camera systems requiring broad scene coverage.

Potential applications include:

• Vehicle-mounted cameras
• Parking and maneuvering cameras
• Side-view cameras
• Rear-view auxiliary cameras
• Blind-spot monitoring
• Compact ADAS camera modules
• Vehicle exterior monitoring

The 92° horizontal FOV allows the camera to capture a broad area while maintaining a more controlled perspective than extremely wide fisheye configurations.

For automotive vision applications, see the ADAS Vision solution.

Outdoor Monitoring

The IP67 waterproof and dust protection allows the lens to be considered for outdoor camera modules exposed to rain, dust, and changing environmental conditions.

Suitable applications include:

• Outdoor surveillance cameras
• Industrial monitoring systems
• Smart infrastructure cameras
• Vehicle and equipment monitoring
• Outdoor embedded vision
• Agricultural equipment cameras

High-Resolution Embedded Vision

This lens is designed around the 1/2.5″ IMX274 sensor configuration with 8MP resolution, making it suitable for compact camera modules where high-resolution image capture and wide scene coverage are both required.

Potential compatible systems include:

• 8MP embedded camera modules
• M12 industrial cameras
• Robotics cameras
• Compact machine vision systems
• Smart monitoring devices
• Mobile vision equipment

The manual focus mechanism can also be useful during camera assembly and optical calibration when the final installation distance needs to be fine-tuned.

For industrial imaging applications, see the Machine Vision solution.

Designed for automotive, outdoor monitoring, embedded vision, and compact high-resolution camera applications requiring wide coverage and IP67 environmental protection.

Optical Configuration and Lens Selection

The lens provides 107° diagonal FOV and < -25% distortion, offering wide scene coverage while retaining a fixed-focal optical configuration. The 4.0mm focal length is suitable for systems where a broad viewing area is required from a compact M12 camera module.

The manual focus configuration allows the installer or camera manufacturer to adjust focus according to the actual sensor and working distance.

The 6G + IRCF optical structure includes an IR Cut Filter, which should not be confused with an IR-corrected optical design.

When matching this lens to a camera sensor, the Sensor Guide can help evaluate sensor format and image-circle compatibility. For selecting focal length and FOV according to the application, the Lens Selection Guide provides additional technical guidance.

Frequently Asked Questions

Q1: What type of lens is this 4.0mm M12 lens?
A: It is a fixed-focal, wide-angle M12 lens designed for 1/2.5″ imaging sensors and 8MP camera systems.

Q2: What is the field of view of the lens?
A: With the IMX274 sensor, the specified FOV is 107° diagonal, 92° horizontal, and 52° vertical.

Q3: Is this lens suitable for 8MP cameras?
A: Yes. The lens is specified for 8MP imaging and uses a 1/2.5″ image format with the IMX274 sensor configuration.

Q4: Is this lens a fisheye lens?
A: No. Although the lens has a wide 107° diagonal FOV and significant distortion, it is positioned as a wide-angle lens rather than a fisheye lens.

Q5: What does the IP67 rating provide?
A: IP67 provides protection against dust and temporary water immersion, making the lens suitable for many automotive and outdoor camera applications.

Q6: What is the benefit of manual focus?
A: Manual focus allows the camera manufacturer or installer to adjust the optical focus according to the actual working distance, sensor configuration, and installation conditions.

Q7: Does IRCF mean the lens is IR corrected?
A: No. IRCF means an IR Cut Filter is included in the lens structure. IR correction refers to a different optical design intended to compensate for wavelength-related focus shifts.

Q8: What applications are suitable for this lens?
A: Typical applications include automotive cameras, ADAS-related imaging, outdoor monitoring, embedded vision, robotics, and compact 8MP camera systems.
