Wide Angle Lens – CCL125042MPFR

4.2mm Wide angle 3 Megapixel High-resolution CCTV lens suppliers, 1/2.5″ F2.0 95° M12/S mount lens, security surveillance lens.

4.2mm 3MP M12 Wide Angle Lens

This 4.2mm 3MP M12 wide angle lens is designed for compact camera modules requiring broad scene coverage in a small optical package. With a 95° diagonal FOV, F2.0 fixed aperture, 0.1m minimum object distance, and M12×0.5 mount, it provides a practical solution for embedded vision, compact surveillance, and space-constrained imaging systems.

M12 Wide Angle Lens Core Highlights

• 95° Wide-Angle Coverage: Provides broad scene coverage for compact camera systems.
• 3MP Resolution: Supports clear imaging for general-purpose embedded vision and surveillance.
• F2.0 Aperture: Provides a useful balance between light transmission and optical compactness.
• M12×0.5 Mount: Enables straightforward integration with compact camera modules and embedded vision hardware.
• 0.1m M.O.D.: Supports imaging at relatively close working distances where near-field scene coverage is important.

For engineers selecting an M12 lens, field of view should be evaluated together with sensor format and working distance. The Lens Selection Guide provides additional guidance for matching lens specifications to imaging requirements.

M12 Wide Angle Lens Applications

Core Application Scenes

This 4.2mm M12 wide angle lens is particularly suitable for compact imaging systems where a relatively wide viewing angle is required without moving to an extreme fisheye design. Its 77° horizontal FOV can help a single camera cover a broad near-field area, while the 0.1m minimum object distance makes it practical for applications where objects may be positioned relatively close to the camera.

The lens can be used in compact indoor surveillance modules, embedded smart cameras, access-control devices, equipment monitoring cameras, and other space-constrained vision systems. Its fixed focal length also provides a straightforward optical configuration for camera designs that do not require variable zoom.

For systems where accurate coverage planning is important, engineers can use the FOV Calculator to estimate the relationship between sensor size, focal length, working distance, and field of view.

Frequently Asked Questions

Q: What type of lens is this 4.2mm lens?
A: It is a fixed focal length M12 lens with a 4.2mm focal length, 3MP resolution, and wide-angle 95° diagonal field of view.

Q: What sensor size is this M12 lens designed for?
A: This lens is designed for a 1/2.5″ image format and provides 3MP imaging performance when appropriately matched with the camera sensor.

Q: What is the field of view of this 4.2mm M12 lens?
A: The lens provides a 95° diagonal FOV, 77° horizontal FOV, and 56° vertical FOV.

Q: Is this lens suitable for close-range imaging?
A: Yes. With a minimum object distance of 0.1m, this lens fits compact imaging systems where the camera captures objects at relatively short working distances.

Q: Is this lens IR corrected?
A: The specification lists an IR cut component, but it does not specify IR-corrected optical performance. Therefore, it should not be described as an IR corrected lens without additional optical test data.

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

Q: Does this lens have variable zoom?
A: No. It uses a fixed focal length of 4.2mm and therefore does not provide variable optical zoom.

Q: How can I determine whether this lens provides enough coverage for my camera?
A: Field of view depends on sensor dimensions, focal length, and working distance. The FOV Calculator can help estimate the required coverage before selecting the lens.

Optical Selection & Related Resources

Selecting an M12 lens requires more than comparing focal length alone. Sensor size, required field of view, working distance, resolution, and mechanical interface should all be considered during the optical selection process.
