Fisheye Lens – S3719620F68

S3719620F68 is Waterproof IP68 4-Megapixel Fisheye lens with Built-In IR Filter, 196° F.O.V., F2.0 aperture, M12 mount, for security surveillance.

M12 0.79mm 4MP IP68 Waterproof Fisheye Automotive Lens

This 0.79mm M12 fisheye lens is designed for ultra-wide automotive and embedded vision applications requiring broad scene coverage in demanding environments. With 196° FOV, 4MP resolution, IP68 waterproof protection, and compatibility with the Sony IMX273 sensor, it provides a compact optical solution for outdoor and vehicle-mounted imaging systems.

The combination of ultra-wide coverage and IP68 protection makes this lens suitable for optical systems that must maintain broad visual awareness while operating in exposed or moisture-prone environments. For engineers evaluating camera coverage, the FOV Calculator can help estimate the relationship between sensor format, installation distance, and field of view.

M12 0.79mm Fisheye Lens Applications

Core Application Scenes

This IP68 M12 fisheye automotive lens is designed for camera systems that require extremely wide visual coverage while operating in exposed environments. Its 0.79mm focal length and 196° field of view allow a single camera module to observe a very broad area around a vehicle or outdoor device.

The IP68 waterproof rating is particularly important for applications exposed to rain, splash water, dust, and changing outdoor conditions. This makes the lens suitable for vehicle-mounted surround-view cameras, outdoor monitoring modules, mobile robotics, and weather-exposed embedded vision systems where a conventional indoor fisheye lens may not provide sufficient environmental protection.

With compatibility with the Sony IMX273 and 4MP resolution, the optical system can provide useful image detail across a very wide scene. The F(θ) distortion specification of below 29% also provides a defined fisheye imaging characteristic suitable for systems that perform image correction, panoramic processing, or computer-vision-based environmental perception.

In automotive applications, the ultra-wide FOV can help capture areas close to the vehicle that may not be visible to conventional forward-facing cameras. It can therefore be considered for surround-view, parking assistance, side-view, close-range environmental perception, and vehicle-mounted monitoring architectures, subject to the complete camera system’s mechanical and environmental requirements.

The 0.2m M.O.D. also makes the lens suitable for close-range scene acquisition, which is useful when the camera is mounted close to surrounding objects or vehicle surfaces. For broader information on optical selection and sensor matching, engineers can refer to the Lens Selection Guide.

Compatible Device List

• Automotive Surround-View Cameras: Suitable for vehicle-mounted camera modules requiring extremely broad visual coverage around the vehicle.
• Parking Assistance Systems: The ultra-wide FOV can capture close-range areas around the vehicle for parking and maneuvering perception.
• Outdoor Vehicle Cameras: IP68 protection supports applications exposed to rain, dust, water splash, and outdoor operating conditions.
• Mobile Robotics Cameras: Useful for autonomous mobile platforms operating in outdoor environments where wide environmental visibility and weather resistance are required.
• Outdoor AI Vision Modules: Suitable for embedded vision devices that require broad image acquisition in exposed environments.
• Industrial Mobile Equipment: Can be integrated into camera systems installed on mobile machinery or equipment requiring waterproof optical protection.
• Custom Automotive Camera Modules: The M12 × 0.5 mount provides a compact interface for customized camera assemblies.

For automotive perception projects, this lens can be evaluated alongside TOWIN’s ADAS solutions, particularly for systems requiring broad visual coverage around a vehicle.

Designed for automotive surround-view, outdoor vehicle imaging, parking assistance, mobile robotics, and IP68-protected wide-area vision applications.

Frequently Asked Questions

Q: Is this an automotive lens?
A: Yes. Its IP68 waterproof protection, ultra-wide 196° FOV, compact M12 mounting, and suitability for vehicle-mounted vision make it applicable to automotive imaging systems.

Q: What sensor is this lens compatible with?
A: The supplied specification identifies the Sony IMX273 sensor, with a maximum image circle of Φ3.7mm.

Q: What is the field of view of this fisheye lens?
A: The specified FOV is 196° diagonally, horizontally, and vertically, providing extremely wide scene coverage.

Q: What is the focal length of this automotive fisheye lens?
A: It uses an ultra-short 0.79mm fixed focal length designed for extremely wide-angle imaging.

Q: Is this a low distortion lens?
A: No. This product is positioned as a fisheye lens rather than a low-distortion lens. Its F(θ) distortion is specified as below 29%, reflecting its ultra-wide fisheye optical design.

Q: What is the minimum object distance of this M12 lens?
A: The specified M.O.D. is 0.2m, allowing close-range objects and areas around the camera to be captured.

Q: What does IRCF mean in the lens structure?
A: IRCF generally refers to an IR Cut Filter. It should not be interpreted as confirmation that the lens is IR corrected. The supplied optical structure is specified as 2G4P + IRCF.

Q: What applications are suitable for this IP68 M12 fisheye lens?
A: Potential applications include automotive surround-view cameras, parking assistance, outdoor vehicle imaging, mobile robotics, outdoor AI vision, and other wide-area imaging systems requiring environmental protection.
