• F1.8 large aperture improves light-gathering capability for demanding low-light imaging conditions.
• 192° horizontal FOV captures an extremely wide lateral scene from a compact camera position.
• 2MP resolution support provides practical image detail for dedicated automotive monitoring systems.
• IP68 waterproof protection supports outdoor vehicle camera installations exposed to water and dust.

1.8mm M12 220° Fisheye Lens Applications

Core Application Scenes

This 1.8mm M12 fisheye automotive lens is developed for vehicle-mounted camera systems where maximum scene coverage is required from a compact optical assembly. Its 220° diagonal and 192° horizontal field of view allow the camera to capture an exceptionally broad surrounding area, making it suitable for close-range environmental observation around vehicles.

The combination of 1.8mm focal length and F1.8 aperture makes this lens particularly useful when the camera must combine an extremely wide viewing angle with efficient light collection. Compared with a slower-aperture wide-angle lens, the F1.8 configuration can provide greater optical throughput for vehicle imaging under reduced ambient light.

The lens can be integrated into side-view, rear-area, front-area, and surrounding-environment camera modules, depending on the required installation geometry. Its extremely wide horizontal FOV is especially useful when the camera needs to monitor a large lateral area from a constrained mounting position.

The IP68 waterproof rating supports outdoor vehicle camera applications where the optical assembly may encounter rain, road splash, dust, and other environmental exposure. The M12X0.5 interface and 14.5mm T.T.L. also provide a compact mechanical configuration for embedded camera housings.

For vehicle perception projects requiring broad optical coverage, this lens can be evaluated as part of ADAS solutions, particularly for close-range environmental imaging where an ultra-wide viewing angle is required.
