설명
A5520220F69 is a high-performance 3-Megapixel Fisheye Automotive Lens featuring an ultra-wide 202° FOV and F2.0 large aperture. Optimized for 1/2.4″ sensors (like ISX031) and M10 mounts, this IP69K waterproof lens is engineered to eliminate blind spots and withstand high-pressure steam cleaning in extreme autonomous driving and security surveillance environments.
Scenario-based Functional Descriptions
- 202° Panoramic View, Eliminating Blind Spots: Designed specifically for surround view systems, a single lens can cover over 180 degrees of hemispherical space, perfectly compatible with the ISX031 sensor, ensuring clear edge images.
- F2.0 Large Aperture, Superior Night Vision: Significantly increases light intake compared to commonly available F2.4 lenses. Captures clearer 3MP details in underground parking garages or at high speeds at night.
- IP69K Industrial-Grade Protection: Not only waterproof (IP67), but also resistant to high-pressure jet wash. This is an essential specification for automotive external cameras and industrial cleaning line vision systems.
- F-θ Low Distortion Control: Despite a 202° field of view, precise optical design controls F-θ distortion to within -3.9%, greatly reducing the pressure on backend algorithm correction and lowering AI recognition latency.

FAQs
Q: Why is IP69K rating important for automotive lenses?
A: IP69K is the highest protection level. Unlike IP67, it ensures the lens can withstand high-pressure, high-temperature washdowns. For automotive cameras, this means long-term reliability against road spray, car washes, and extreme weather.
Q: Can this 1.7mm lens be used with other sensors besides ISX031?
A: Yes, it supports any image format up to 1/2.4″ (Φ5.51mm). However, it is optically optimized for the ISX031 to provide a full 202° horizontal FOV without vignetting.
Q: What is the benefit of F-theta distortion below -3.9% in a fisheye lens?
A: Standard fisheye lenses often have massive distortion that blurs edge details. Our -3.9% F-theta design ensures a more linear image mapping, which improves the accuracy of Object Detection (ADAS) and reduces CPU load for dewarping.
