Wide Angle Lens – CCL130420MPF

CCL130420MPF is 4.0mm Wide Angle Lens with Built-In Filter 1/3″ 3-Megapixel HD lens, 97° Low F-number S-Mount Lens (F2.0) security surveillance Lens.

4.0mm M12 3MP Wide Angle Lens for Compact Vision Systems

This 4.0mm M12 wide angle lens is designed for 1/3″ camera systems requiring broad scene coverage in a compact optical configuration. With 97° diagonal FOV, 70° horizontal FOV, 52° vertical FOV, 3MP resolution, and an F2.0 aperture, it provides a practical balance between wide-angle coverage and image detail for embedded vision, monitoring, and industrial imaging applications.

The M12 mount, 7.5mm BFL, fixed iris, and manual focus configuration make this lens easy to integrate into compact camera modules where installation space and consistent optical configuration are important. Its IRCF construction is also suitable for camera systems using an integrated infrared-cut filter arrangement.

M12 Wide Angle Lens Core Highlights

• 97° Wide-Angle Coverage: The 4.0mm focal length provides 97° diagonal and 70° horizontal FOV for broad scene capture without using an ultra-short focal length.
• 3MP Imaging Performance: Designed for 1/3″ camera systems requiring practical image resolution for embedded and monitoring applications.
• F2.0 Aperture: The relatively wide aperture supports efficient light collection for indoor and general-purpose imaging environments.
• Compact M12 Integration: The M12 mount allows straightforward integration into compact camera modules and space-constrained imaging equipment.
• IR Cut Filter Configuration: The IRCF structure supports camera designs requiring an integrated infrared-cut filter, while the lens should not be considered optically IR corrected unless additional IR correction data is specified.

M12 Wide Angle Lens Applications

Core Application Scenes

This 4.0mm M12 lens is designed for camera systems that need a moderately wide field of view with compact mechanical integration. Compared with ultra-wide lenses using shorter focal lengths, its 70° horizontal FOV provides a more controlled viewing range while still covering a relatively large scene.

The combination of 3MP resolution, F2.0 aperture, M12 mounting, and fixed optical configuration makes it suitable for embedded industrial cameras, smart monitoring equipment, indoor security cameras, and compact vision modules.

For industrial imaging systems where the field of view must cover a larger working area from a relatively short installation distance, this lens can provide a practical optical starting point. For more demanding inspection systems requiring higher resolution or significantly lower distortion, TOWIN’s Machine Vision solutions can be considered.

Designed for compact wide-angle imaging applications, this lens is particularly suitable when camera size, scene coverage, and optical simplicity need to be balanced.

Frequently Asked Questions

Q: What sensor size is this 4.0mm M12 lens designed for?
A: This lens is designed for a 1/3″ image format and provides a 97° diagonal, 70° horizontal, and 52° vertical field of view.

Q: Is the 4.0mm lens suitable for wide-angle applications?
A: Yes. Its 97° diagonal and 70° horizontal FOV provide wide-angle coverage for compact industrial, monitoring, and embedded camera systems.

Q: Is this a low distortion M12 lens?
A: No. With specified distortion below -18%, this model is better positioned as a standard wide-angle lens rather than a dedicated low distortion lens.

Q: What does “With IRCF” mean?
A: IRCF indicates that the lens structure is configured with an infrared cut filter. It does not by itself confirm IR-corrected optical performance across visible and near-infrared wavelengths.

Q: What is the aperture of this lens?
A: The lens uses a fixed F2.0 aperture, providing a relatively wide optical aperture for general indoor and embedded imaging applications.

Q: What mount does this lens use?
A: This model uses an M12 mount, which is widely used in compact camera modules, embedded vision systems, and small-form-factor imaging devices.

Q: Can this lens be used for machine vision?
A: Yes, it can be used for selected machine vision applications where wide scene coverage and compact integration are priorities. Applications requiring very low distortion or higher-resolution imaging may require a specialized machine vision lens.
