Automotive Lens – A5120020F69

A5120020F69 is 1.9mm 8-Megapixel Fisheye Automotive lens with IRCF, IP69K waterproof rating, for 1/2.9″ sensor, A-A (Active Alignment technology).

1.9mm 8MP IP69K Fisheye Automotive Lens

This 1.9mm 8MP fisheye automotive lens delivers an ultra-wide 200° field of view for panoramic imaging where a single camera needs to capture an exceptionally large scene. With F2.0 aperture, fixed focus, 8MP resolution, IRCF construction, and IP69K protection, it is designed for compact and rugged automotive, industrial, and embedded vision systems.

IP69K Automotive Lens Core Highlights

• 200° Ultra-Wide FOV: Captures an exceptionally broad scene with a single camera.
• 8MP High-Resolution Imaging: Provides detailed image capture for demanding vision systems.
• IP69K Protection: Built for applications exposed to water, dust, and demanding operating conditions.
• 1.9mm F2.0 Optical Design: Combines an ultra-short focal length with a relatively fast aperture.
• Compact 14mm T.T.L.: Supports integration into compact embedded imaging equipment.

1.9mm IP69K Automotive Lens Applications

Core Application Scenes

This 1.9mm fisheye lens is designed for applications where maximizing scene coverage is more important than maintaining conventional rectilinear image geometry. Its 200° diagonal and horizontal FOV allows a single camera to observe an exceptionally broad surrounding area, making it suitable for panoramic and surround-view imaging systems.

In automotive applications, the lens can be integrated into compact camera modules that require extensive environmental coverage. Its IP69K-rated construction makes it particularly suitable for externally mounted or exposed camera systems where resistance to high-pressure water, dust, and harsh cleaning conditions is required.

For industrial applications, the ultra-wide FOV can reduce the number of cameras needed to monitor large or confined areas. The 8MP resolution provides substantially more image detail than lower-resolution panoramic modules, while the F2.0 aperture supports image capture in challenging lighting conditions.

The lens can also be considered for robotic and embedded vision equipment where the camera must observe a large surrounding area from a compact installation position. For broader information about optical integration and lens selection, engineers can review the Optical Design resources.

Optical Performance & System Integration

The 200° FOV and < -19% F-θ distortion indicate that this is intentionally designed as a fisheye/ultra-wide optical system rather than a conventional low-distortion lens. The strong distortion characteristic allows the lens to achieve extremely broad image coverage within a compact optical package.

When integrating this lens with the AR0830 sensor, the specified FOV is 200° diagonal, 200° horizontal, and 100° vertical. System designers should therefore evaluate the required image coverage together with the camera mounting position and image-processing pipeline.

Because the lens uses an A-A mount, 14mm T.T.L., and 6G + IRCF construction, mechanical space and camera-module compatibility should be verified during system design. Engineers can use the Lens Selection Guide when comparing optical parameters for a new camera design.

For projects requiring a specific viewing angle or coverage area, the FOV Calculator can also help estimate the relationship between sensor format, focal length, and field of view.

Frequently Asked Questions

Q: Is this 1.9mm lens a fisheye lens?
A: Yes. The 200° diagonal and horizontal FOV clearly place this lens in the fisheye/ultra-wide-angle category.

Q: What is the field of view of this lens?
A: When paired with the specified AR0830 sensor, the FOV is 200° diagonal, 200° horizontal, and 100° vertical.

Q: Is this lens a low distortion lens?
A: No. Its F-θ distortion is specified as < -19%. This is characteristic of an ultra-wide/fisheye optical design rather than a low-distortion imaging lens.

Q: What resolution does this fisheye lens support?
A: The specified optical resolution is 8 Megapixel, making it suitable for high-resolution panoramic and wide-area imaging systems.

Q: Is this lens suitable for automotive applications?
A: Yes. Its 1.9mm focal length, 200° FOV, compact 14mm T.T.L., and IP69K construction make it suitable for rugged automotive camera applications requiring extensive scene coverage.

Q: What does the IP69K rating provide?
A: The IP69K specification indicates a rugged enclosure-level design intended for demanding environments involving dust and high-pressure/high-temperature water exposure when properly integrated into the complete camera assembly.

Q: Does this lens have an IR-cut filter?
A: Yes. The construction is specified as 6G + IRCF, indicating that an IR-cut filter is incorporated into the optical construction.

Q: Is the focus adjustable?
A: The specification lists Manual Focus, so the focus position can be mechanically adjusted during camera assembly or optical calibration.
