Wide Angle Lens – CCL1230420MPF

CCL1230420MPF 4mm 12-Megapixel M12 wide angle lens with 120° FOV, 1/2.3″ format

4mm 12MP M12 Wide Angle Lens

This 4mm 12MP M12 wide angle lens is designed for high-resolution camera systems that require broad scene coverage with a 1/2.3″ image format. With a 120° diagonal FOV, 93° horizontal FOV, F2.0 aperture, and M12 mount, it provides a strong combination of high-resolution imaging and wide-angle coverage for compact surveillance, smart camera, and monitoring applications.

The 4mm fixed focal length, 6G optical construction, and integrated IR cut filter provide a practical optical configuration for camera modules that require detailed imaging across a relatively wide viewing area while maintaining a compact M12 interface.

Product Core Highlights

• 12MP high-resolution imaging — Designed for camera systems requiring detailed image capture.
• 120° diagonal wide FOV — Provides broad scene coverage while retaining a 4mm focal length.
• 1/2.3″ image format — Supports camera designs using a relatively large sensor format.
• F2.0 aperture — Provides a relatively bright optical configuration for general surveillance and monitoring environments.
• 6G + IR Cut Filter construction — Combines a multi-element optical design with an integrated IR-cut filtering configuration.

M12 Wide Angle Lens Applications

The 4mm 12MP M12 lens is well suited to applications that need high-resolution wide-angle imaging rather than simply maximum field of view. Its 93° horizontal FOV provides substantial scene coverage, while the 12MP resolution helps preserve image detail across the monitored area.

Typical applications include high-resolution CCTV cameras, indoor surveillance systems, smart security cameras, building monitoring, entrance monitoring, retail observation, and compact wide-area monitoring devices. The 4mm focal length offers a useful balance between wide coverage and image detail, making it suitable for installations where an extremely short focal length is not required.

The 1/2.3″ image format makes this lens particularly relevant to camera modules using larger image sensors than typical compact 1/3″ configurations. Its fixed iris and fixed focal length also provide a straightforward optical architecture for stable camera installations.

Compatible devices: 1/2.3″ compatible camera modules, high-resolution CCTV cameras, smart security cameras, indoor monitoring cameras, retail monitoring systems, building surveillance cameras, entrance-monitoring devices, and embedded wide-angle camera modules.

When selecting a sensor for this lens, the Sensor Guide can help you compare sensor formats and optical compatibility. For applications requiring a specific viewing range, the FOV Calculator can also be used to evaluate field-of-view requirements.

Frequently Asked Questions

Q: What type of lens is the 4mm 12MP lens?
A: It is a fixed focal length M12 wide angle lens featuring a 4mm focal length, 120° diagonal FOV, and 93° horizontal FOV.

Q: What sensor size is this 12MP M12 lens designed for?
A: The specified image format is 1/2.3″. The final sensor should be verified against the lens image circle and the specific camera module design.

Q: Is this a fisheye lens?
A: The lens should not automatically be classified as a fisheye lens. It has a wide 120° diagonal FOV, but the supplied specifications identify it as a wide-angle configuration rather than a fisheye design.

Q: Is this a low-distortion lens?
A: No. With distortion specified as less than 35%, this product is better positioned as a high-resolution wide-angle M12 lens rather than a dedicated low-distortion lens.

Q: What applications are suitable for this 4mm M12 lens?
A: It is suitable for high-resolution CCTV, indoor surveillance, smart security cameras, building monitoring, entrance monitoring, retail observation, and other wide-area imaging applications.

Q: What does the IR Cut Filter do?
A: An IR Cut Filter is used to reduce unwanted infrared wavelengths in visible-light camera systems. It is different from an IR-corrected optical design, which specifically maintains focus and optical performance across different wavelengths.

Q: Does the lens have a fixed aperture?
A: Yes. The lens uses a fixed F2.0 aperture and fixed iris, providing a straightforward optical configuration for stable camera installations.

Q: Can TOWIN customize this type of M12 lens?
A: TOWIN can evaluate customized optical requirements such as focal length, sensor format, FOV, mount, and other performance parameters according to the target camera system.
