Wide Angle Lens – S6918520F

S6918520F is Wide-angle 8-Megapixel M12-mount CCTV lens with Built-In IR Filter, 167° diagonal FOV, F2.0 aperture, for security surveillance.

2.1mm 8MP M12 Ultra Wide Angle Lens

This 2.1mm M12 ultra wide angle lens is designed for high-resolution imaging systems that require an exceptionally wide field of view with controlled geometric distortion. Featuring 8MP resolution, a 167° diagonal FOV, F2.0 aperture, and M12 × 0.5 mounting, it is well suited for compact embedded vision, panoramic imaging, robotics, and wide-area monitoring applications.

The combination of a 2.1mm focal length and 167° diagonal field of view makes this lens suitable for applications where a single camera needs to capture a very large scene area. For optical system planning, the FOV Calculator can help engineers evaluate field coverage based on sensor and working-distance requirements.

Product Core Highlights

• 167° Ultra Wide FOV: Captures an exceptionally broad scene with a single camera.
• 8MP High Resolution: Provides detailed imaging for modern embedded vision systems.
• Controlled F-Theta Distortion: Less than -1.9% distortion helps maintain more usable wide-angle imagery.
• F2.0 Aperture: Provides a relatively bright optical configuration for compact imaging systems.
• M12 × 0.5 Mount: Supports integration into compact camera and embedded vision modules.

2.1mm M12 Wide Angle Lens Applications

Core Application Scenes

This 8MP M12 wide angle lens is designed for imaging scenarios where maximizing scene coverage is more important than using a conventional narrow or moderate field of view. Its 167° diagonal FOV allows a compact camera module to observe a large surrounding area while the controlled F-Theta distortion helps reduce the geometric deformation normally associated with extremely wide-angle optics.

For robotics vision, the wide viewing range can help mobile robots and autonomous platforms maintain broader environmental awareness without relying on multiple cameras for basic peripheral coverage. Its compact M12 × 0.5 interface also makes it practical for embedded camera assemblies where optical space is limited.

In panoramic and wide-area monitoring, the 2.1mm focal length can cover a large scene from a relatively short installation distance. This can be useful for compact monitoring devices, indoor spatial awareness cameras, and embedded vision modules that need to observe people, equipment, or surrounding areas within a single frame.

The 0.2m minimum object distance also supports relatively close-range imaging. This makes the lens suitable for compact devices that need to capture a broad scene while operating close to the target environment.

For system designers comparing different focal lengths, the Lens Selection Guide provides additional information on selecting optics according to sensor size, FOV, working distance, and application requirements.

Frequently Asked Questions

Q: What is the focal length of this M12 wide angle lens?
A: This lens uses a fixed 2.1mm focal length, providing a very wide field of view for compact imaging applications.

Q: What is the field of view of this 2.1mm lens?
A: The specified FOV is 167° diagonal, 145° horizontal, and 81° vertical when used with the specified IMX662 configuration.

Q: Is this an 8MP M12 lens?
A: Yes. The lens is specified with 8MP resolution, making it suitable for high-resolution compact imaging systems.

Q: Is this lens a fisheye lens?
A: This product is classified as a Wide Angle Lens rather than a Fisheye Lens. Although its 167° diagonal FOV is extremely wide, the specified F-Theta distortion is below -1.9%, and the product is positioned for controlled ultra-wide-angle imaging.

Q: What does the F-Theta distortion specification mean?
A: F-Theta distortion describes image-position deviation in wide-angle optical systems. A specification below -1.9% indicates controlled distortion performance for an extremely wide field of view.

Q: What type of mount does this lens use?
A: The lens uses an M12 × 0.5 mount, making it suitable for compact embedded camera modules and other M12-based imaging systems.

Q: What is the minimum object distance of this M12 lens?
A: The specified M.O.D. is 0.2m, allowing the lens to be used for relatively close-range wide-area imaging.

Q: Does the IRCF specification mean that the lens is IR corrected?
A: Not necessarily. The specification states that the lens is equipped with IRCF. In this product configuration, IRCF is treated as an IR cut filter rather than evidence of full-spectrum IR correction.
