Wide Angle Lens – S03412610316F69

S03412610316F69 is M12 Wide angle CCTV lens with Built-In IR Filter, 123° diagonal F.O.V., F1.6 aperture, IP69K Waterproof Automotive Lens for security surveillance.

3.4mm M12 Wide Angle Lens

This 3.4mm M12 wide angle lens delivers a 123° diagonal field of view with a fast F1.6 aperture and IP69K waterproof protection. Designed for automotive cameras, ADAS sensing, outdoor monitoring, and compact machine vision systems, it provides broad scene coverage in a compact M12 package.

For systems requiring a compact lens with wide-angle coverage, the M12 Lens product range provides additional focal lengths and optical configurations.

M12 Wide Angle Lens Core Highlights

• 123° diagonal FOV — captures a broad scene with a 3.4mm focal length.
• F1.6 aperture — provides strong light-gathering capability for compact imaging systems.
• IP69K protection — suitable for demanding automotive and outdoor environments exposed to water, dust, and cleaning processes.
• Compact M12x0.5 mount — easy to integrate into small camera modules and embedded vision systems.
• 0.2m MOD — supports relatively close-range imaging applications where wide scene coverage is required.

3.4mm M12 Wide Angle Lens Applications

Automotive and ADAS Imaging

The combination of a 3.4mm focal length, 123° diagonal FOV, F1.6 aperture, and IP69K protection makes this lens suitable for automotive cameras that need broad scene coverage from a compact optical assembly.

It can be considered for:

• Surround-view and auxiliary vehicle cameras
• Front or side-view automotive camera modules
• Parking and maneuvering vision
• Blind-spot monitoring cameras
• Outdoor vehicle perception systems
• Compact ADAS camera assemblies

The wide-angle optical design allows the camera to cover a larger area without requiring a physically large lens assembly.

For broader automotive vision requirements, see the ADAS Vision solution.

Outdoor and Harsh-Environment Monitoring

IP69K protection makes this lens suitable for applications where the camera may be exposed to water, dust, vibration, or high-pressure cleaning.

Potential applications include:

• Outdoor surveillance cameras
• Industrial vehicle cameras
• Agricultural machinery vision
• Construction equipment cameras
• Mobile robotics
• Harsh-environment monitoring systems

The F1.6 aperture can also provide an optical advantage when the camera operates under changing or relatively low-light conditions.

Compact Embedded Vision

The M12x0.5 mount and 21.4mm TTL make the lens suitable for compact camera modules where installation space is limited.

Compatible systems may include:

• M12 industrial cameras
• Embedded vision modules
• Compact CMOS camera boards
• Robotics cameras
• Mobile machine vision systems
• Vehicle-mounted imaging modules

When selecting the lens for a specific CMOS sensor, the Sensor Guide can help verify sensor format and image-circle compatibility.

Designed for automotive, ADAS, outdoor monitoring, and compact embedded vision applications where wide field coverage and IP69K environmental protection are required.

Optical Configuration and Lens Selection

With 123° diagonal FOV and < -43% distortion, this lens is designed for applications that prioritize wide scene coverage rather than geometrically corrected images.

The strong wide-angle distortion can be useful when maximizing the visible scene within a small optical package. If the application requires straighter lines and more geometrically accurate imaging, compare it with TOWIN’s Low Distortion Lens range.

For selecting focal length according to object distance, sensor size, and required field of view, the Lens Selection Guide provides additional technical guidance.

Frequently Asked Questions

Q1: What type of lens is the 3.4mm M12 lens?
A: It is a fixed-focal M12 wide-angle lens with a 123° diagonal FOV and strong barrel distortion, making it suitable for wide-scene and fisheye-style imaging applications.

Q2: Is this lens suitable for automotive cameras?
A: Yes. Its IP69K waterproof protection, compact M12 mount, wide FOV, and F1.6 aperture make it suitable for various automotive and vehicle-mounted imaging applications.

Q3: What sensor is this lens tested with?
A: The listed FOV specification is based on the OX03C10 sensor, with a 2MP imaging configuration.

Q4: What is the field of view of this 3.4mm lens?
A: With the OX03C10 sensor, the specified FOV is 123° diagonal, 102° horizontal, and 67° vertical.

Q5: Does “With IRCF” mean this is an IR corrected lens?
A: No. IRCF refers to an IR Cut Filter. It should not be confused with an IR-corrected optical design, which compensates for focus shifts between visible and near-infrared wavelengths.

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

Q7: What is the minimum object distance?
A: The specified minimum object distance is 0.2 meters, making the lens suitable for relatively close-range wide-angle imaging.

Q8: Can this lens be used with other M12 camera modules?
A: The lens uses an M12x0.5 mount, but the camera’s sensor format, image circle, mechanical clearance, and required FOV should be checked before integration. TOWIN’s M12 Lens solutions provide additional guidance for compact camera designs.
