1.7mm M12 212° Fisheye Lens Applications

Core Application Scenes

The combination of a 1.7mm focal length and up to 212° field of view is designed for imaging systems that need to capture an exceptionally large area from a single camera position. This makes the lens different from conventional wide-angle optics, particularly when the camera must observe areas extending significantly beyond the normal forward-facing field of view.

For automotive vision, the IP69K-rated construction provides an important advantage in vehicle-mounted environments exposed to water, dust, road contamination, and high-pressure cleaning. The ultra-wide optical coverage can be considered for exterior camera modules and other automotive imaging systems where a broad surrounding view is required.

In machine vision, the combination of 1.3MP resolution and F-θ distortion below -5% provides a balance between very broad coverage and controlled geometric distortion. It can be used for applications where the inspection system needs to monitor a large area while retaining more manageable image geometry than an extremely distorted fisheye design.

For robotics vision, the 212° FOV can provide extensive environmental visibility around compact robotic platforms. The 0.1m M.O.D. is particularly useful when the camera operates close to objects or structures and needs to maintain a wide view of the surrounding area.

The F1.8 aperture provides a relatively bright optical system for applications where maintaining adequate image brightness is important. Combined with IP69K protection, the lens can be considered for outdoor or exposed vision equipment where both optical coverage and environmental protection are required.

The specified F-θ distortion of < -5% is also a key differentiating parameter. Although the lens provides fisheye-level coverage, its distortion is more controlled than many extreme ultra-wide fisheye configurations. This makes it relevant to systems where broad coverage and manageable image distortion need to be considered together.

Frequently Asked Questions

Q: What is the maximum field of view of this 1.7mm M12 lens?
A: The lens provides a specified field of view of 212° when used with the Φ5.72 image format. The listed FOV values are 194° at Φ5.38 and 142° at Φ4.03.

Q: Is this lens a fisheye lens?
A: Yes. The extremely wide 212° FOV places this lens in the fisheye category. Its F-θ distortion below -5% indicates a more controlled distortion characteristic compared with many extreme fisheye designs.

Q: Can this lens be classified as a Low Distortion Lens?
A: Yes. Rated below ‑5%, the F‑θ distortion enables this lens to serve as a controlled low‑distortion ultra‑wide / fisheye solution. Still, it is not a standard rectilinear low‑distortion lens given its over‑200° FOV.

Q: Is this lens suitable for automotive applications?
A: Yes. The IP69K waterproof rating and ultra-wide field of view make it suitable for automotive imaging environments where strong environmental protection and broad scene coverage are required.

Q: What does the IP69K rating mean for this lens?
A: IP69K indicates a high level of protection against dust and high-pressure, high-temperature water exposure, making the lens suitable for demanding outdoor and vehicle-mounted environments.

Q: What is the minimum object distance?
A: The specified M.O.D. is 0.1m, allowing the lens to capture very close objects while maintaining its ultra-wide field of view.

Q: What does IRCF mean in the 5G2MG+IRCF structure?
A: IRCF refers to an infrared cut filter. It should not be interpreted as IR correction. The filter controls infrared wavelengths reaching the image sensor.

Q: What type of camera mount does this lens use?
A: The lens uses an M12x0.5 mount, making it suitable for compact M12 camera modules and embedded vision systems.
