4.3mm M12 IP69K Automotive Lens Applications

Automotive Camera Systems

The combination of a 4.3mm focal length, 96° diagonal FOV, IP69K protection, and compact M12x0.5 mount makes this lens suitable for various vehicle-mounted imaging systems.

Potential applications include:

• Parking cameras
• Side-view cameras
• Rear-view auxiliary cameras
• Blind-spot monitoring
• Vehicle exterior monitoring
• Compact automotive camera modules
• Industrial vehicle cameras

The 74° horizontal FOV provides useful lateral coverage while avoiding the extreme geometric distortion associated with very wide fisheye optics.

Harsh-Environment Imaging

The IP69K waterproof and dust protection makes this lens suitable for camera systems exposed to demanding environmental conditions, including water spray, dust, and high-pressure cleaning processes.

Potential applications include:

• Heavy-duty vehicle cameras
• Agricultural machinery vision
• Construction equipment cameras
• Outdoor monitoring systems
• Industrial vehicle imaging
• Smart infrastructure cameras

The robust environmental specification allows the lens to be considered for camera modules installed outside protected indoor enclosures.

Designed for automotive, outdoor monitoring, industrial vehicle, and harsh-environment imaging applications requiring wide coverage and IP69K protection.

Compact Embedded Vision

With an M12x0.5 mount, 21.2mm TTL, 7.9mm BFL, and 0.2m MOD, this lens is suitable for compact camera assemblies where mechanical integration space is limited.

Potential compatible devices include:

• M12 embedded cameras
• Compact CMOS camera modules
• Robotics cameras
• Mobile vision systems
• Industrial monitoring cameras
• Vehicle-mounted camera modules

For industrial applications requiring compact optical integration, the Machine Vision solution provides additional information.

Sensor Compatibility and CRA

The lens is specified for the 1/2.5″ AR0521 sensor and has a CRA below 15°. This is an important consideration when matching the lens to an image sensor because the angular relationship between the lens chief ray and the sensor’s pixel structure can affect image quality and illumination uniformity.

When evaluating alternative sensors or camera modules, use the Sensor Guide to check sensor format and optical compatibility.

Optical Configuration

The 6G + IRCF construction provides a multi-element optical configuration for the 4.3mm wide-angle design. The lens combines broad scene coverage with a relatively compact mechanical package.

The specified < -28% distortion should be considered during system calibration and image processing. This lens is intended for wide-angle coverage rather than applications requiring highly accurate geometric reproduction.

For applications where distortion performance is a key selection factor, the Distortion Guide explains how lens distortion affects captured images.

The included IRCF is an IR Cut Filter, not an IR-corrected optical design.

Frequently Asked Questions

Q1: What type of lens is the 4.3mm M12 lens?
A: It is a fixed-focal, wide-angle M12 lens designed for 1/2.5″ imaging sensors and compact camera systems.

Q2: What is the field of view of this lens?
A: With the AR0521 sensor, the specified FOV is 96° diagonal, 74° horizontal, and 55° vertical.

Q3: Is this lens suitable for automotive applications?
A: Yes. The IP69K protection, wide FOV, compact M12 mount, and fixed-focal configuration make it suitable for various automotive and vehicle-mounted imaging applications.

Q4: Is the 4.3mm lens a fisheye lens?
A: No. It provides a wide 96° diagonal FOV, but it is positioned as a wide-angle lens rather than a fisheye optical design.

Q5: What does the CRA <15° specification mean?
A: CRA, or Chief Ray Angle, describes the angle at which chief rays reach the image sensor. A CRA below 15° can help support optical compatibility with sensors designed for relatively low incident ray angles.

Q6: What does IP69K protection provide?
A: IP69K provides a high level of protection against dust and powerful high-temperature water jets, making the lens suitable for demanding outdoor and industrial environments.

Q7: Does IRCF mean the lens is IR corrected?
A: No. IRCF refers to an IR Cut Filter. An IR-corrected lens uses a different optical design to compensate for focus shifts caused by different wavelengths.

Q8: What is the minimum object distance?
A: The specified minimum object distance is 0.2 meters, allowing the lens to capture relatively close subjects with its wide field of view.
