Wide Angle Lens – S02513011022F

S02513011022F is Wide angle 1/3″ CCTV 3-Megapixel lens with Built-In IR Filter, M12/S-Mount, 130° diagonal F.O.V., F2.2 aperture, for security surveillance.

2.5mm M12 Wide Angle Lens

This 2.5mm 3MP M12 low distortion wide angle lens is designed for compact camera modules that require broad scene coverage without the extreme geometric distortion associated with fisheye optics. With up to 130° diagonal FOV, less than 15% distortion, 3MP resolution, and a compact M12 x 0.5 mount, it is suitable for embedded vision, monitoring, robotics, and other wide-angle imaging applications.

M12 Wide Angle Lens Core Highlights

• 2.5mm wide-angle focal length provides up to 130° diagonal FOV for broad scene coverage.
• Less than 15% distortion provides more controlled image geometry than strongly distorted fisheye optics.
• 3MP resolution supports detailed imaging for compact embedded camera systems.
• Dual sensor compatibility provides different FOV configurations with 1/3″ and 1/4″ image sensors.
• Compact M12 x 0.5 mount makes the lens suitable for space-constrained camera modules.
• 5G optical construction with IRCF provides a compact optical configuration for visible-light imaging.

2.5mm M12 Wide Angle Lens Applications

Core Application Scenes

This lens is designed for applications that need a wide viewing angle but still require reasonably controlled geometric distortion. Its 2.5mm focal length and less-than-15% distortion make it a practical alternative to strongly distorted fisheye optics when the captured image needs to remain easier to interpret or process.

Wide-angle embedded camera modules
The compact M12 x 0.5 interface and 14.5mm total track length make the lens suitable for small camera assemblies where installation space is limited. The 3MP resolution provides sufficient image detail for general-purpose monitoring and visual analysis.

Robotics and mobile vision
The 130° diagonal FOV allows a compact camera to monitor a relatively large area around a robot or mobile platform. Controlled distortion can also simplify downstream image processing compared with highly distorted fisheye optics.

Indoor monitoring and smart vision
The broad FOV is useful for monitoring larger areas from a fixed camera position. The lens can be integrated into compact smart cameras where wide scene coverage is required without using a conventional longer focal-length lens.

Machine and equipment monitoring
The short 0.1m minimum object distance allows the lens to capture relatively close scenes, making it suitable for monitoring equipment, components, work areas, and other nearby objects.

Compact security and embedded imaging systems
The 1/3″ and 1/4″ sensor FOV options provide flexibility when developing compact camera modules for different image sensor configurations.

Optical Selection Considerations

The main optical characteristic of this lens is the balance between wide FOV and controlled distortion. With 130° diagonal FOV and distortion below 15%, it is positioned between conventional wide-angle optics and strongly distorted fisheye designs.

The lens also provides different viewing angles depending on sensor size. On a 1/3″ sensor, the specified FOV reaches 130° diagonal, 110° horizontal, and 75° vertical, while the 1/4″ configuration provides 100° diagonal, 80° horizontal, and 65° vertical FOV.

When selecting a lens, sensor format should therefore be evaluated together with the required field of view. The Sensor Guide provides additional information about sensor and lens matching.

For applications where geometric distortion is an important design consideration, the Distortion Guide can help with lens selection.

Frequently Asked Questions

Q: What is the field of view of this 2.5mm M12 lens?
A: With a 1/3″ sensor, the lens provides 130° diagonal, 110° horizontal, and 75° vertical FOV. With a 1/4″ sensor, the specified FOV is 100° diagonal, 80° horizontal, and 65° vertical.

Q: Is this lens a fisheye lens?
A: No. Although the lens provides a very wide 130° diagonal FOV, its specified distortion is below 15%, indicating a more controlled wide-angle optical design rather than a strongly distorted fisheye configuration.

Q: Is this a low distortion lens?
A: Yes. With distortion below 15%, this model can be positioned as a low distortion wide-angle M12 lens compared with strongly distorted fisheye optics.

Q: What sensor sizes are compatible with this lens?
A: The lens is specified for a 1/3″ image format and also provides a dedicated FOV specification for 1/4″ sensors.

Q: What is the minimum object distance?
A: The M.O.D. is 0.1m, allowing the lens to capture relatively close objects.

Q: What mount does this lens use?
A: The lens uses an M12 x 0.5 mount, which is commonly used in compact embedded camera modules.

Q: Does IRCF mean that the lens is IR corrected?
A: No. IRCF refers to an IR Cut Filter. It should not be interpreted as an IR-corrected optical design.

Q: Can this lens be customized for a specific camera module?
A: Yes. TOWIN can discuss optical and mechanical requirements such as sensor format, FOV, distortion, mounting dimensions, and other camera-module specifications through the Contact page.
