Wide Angle Lens – CCL128021MPR

CCL128021MPR HD CCTV wide angle 2.1mm M12 S-mount board lens F2.0 tailor distortion surveillance

2.1mm 1MP M12 Ultra Wide Angle Fixed Focal Lens

This 2.1mm M12 lens is an ultra wide angle lens designed for compact camera systems that require exceptionally broad scene coverage. With a 160° diagonal FOV, 135° horizontal FOV, F2.0 aperture, and 1/2.8″ image format, it provides an expansive viewing area for monitoring and embedded imaging applications.

Featuring an M12 × 0.5 mount, manual focus, fixed iris, and a compact 6G optical construction, this M12 wide angle lens is well suited to space-constrained camera modules. Its 0.2m minimum object distance also supports relatively close-range wide-area imaging.

Product Core Highlights

• 2.1mm ultra-wide-angle focal length delivers up to 160° diagonal FOV for extensive scene coverage.
• 135° horizontal FOV captures a very broad area with a compact camera installation.
• Megapixel optical performance supports 1/2.8″ sensor-based imaging systems.
• F2.0 aperture provides efficient light transmission for general imaging applications.
• M12 × 0.5 compact mount simplifies integration into small embedded camera modules.

Wide Angle Lens Applications

The primary advantage of this lens is its ultra-wide field of view. With a 160° diagonal and 135° horizontal viewing angle, the 2.1mm focal length is suitable for camera systems where maximizing scene coverage is more important than minimizing geometric distortion.

Typical applications include:

• Wide-area security monitoring cameras
• Indoor surveillance and monitoring devices
• Smart home and IoT cameras
• Compact embedded camera modules
• Panoramic monitoring systems
• Door and entrance monitoring cameras
• Vehicle interior monitoring cameras
• Space-constrained wide-angle imaging devices
• Small-format CMOS camera modules

The -59% optical distortion should be considered when integrating the lens into an imaging system. This level of distortion is characteristic of an ultra-wide-angle optical design and can be appropriate for applications where extremely broad coverage is the priority. If the application requires highly accurate geometric reproduction, a lower-distortion optical configuration should be selected instead.

The 0.2m M.O.D. makes this lens suitable for close-range scenes, while its 2.1mm focal length enables a large amount of visual information to be captured from a relatively short camera-to-subject distance.

Frequently Asked Questions

Q: What is the focal length of this M12 lens?
A: The lens has a 2.1mm fixed focal length, making it an ultra-wide-angle option for compact camera systems.

Q: What is the field of view of the 2.1mm M12 lens?
A: It provides a 160° diagonal FOV, 135° horizontal FOV, and 88° vertical FOV on the specified 1/2.8″ image format.

Q: Is this a low-distortion M12 lens?
A: No. The specified optical distortion is -59%. This lens is designed primarily for extremely wide scene coverage rather than low-distortion imaging.

Q: What sensor format is this lens designed for?
A: The specified image format is 1/2.8″, with megapixel-level resolution performance.

Q: Does this lens have a fixed or variable focal length?
A: It has a fixed 2.1mm focal length. The zoom specification is also fixed, so it does not provide optical zoom functionality.

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

Q: What applications benefit from a 160° wide-angle lens?
A: Applications requiring very broad scene coverage can benefit from this lens, including security monitoring, smart home cameras, entrance monitoring, embedded vision, and compact panoramic imaging systems.

Q: What should I consider when selecting an ultra-wide-angle lens?
A: Sensor format, focal length, FOV, working distance, distortion, aperture, and available installation space should be evaluated together. The FOV Calculator can help estimate the relationship between focal length, sensor size, and field of view.
