Fisheye Lens – S02512512524F

S02512512524F is 1/2.5″ 2.5mm High-Quality wide-angle fisheye lens, M12x0.5 mount, 5-Megapixel resolution, F2.4 aperture industrial surveillance lens.

5MP 2.5mm M12 160° Ultra-Wide Fisheye Lens

This 5MP 2.5mm M12 ultra-wide fisheye lens is designed for compact camera systems that require extensive scene coverage from a short focal length. With a 160° diagonal FOV, 125° horizontal FOV, and 90° vertical FOV, it captures a broad surrounding area for smart security, indoor monitoring, robotics perception, and embedded vision applications.

Designed for 1/2.5″ image formats, the lens combines a 5MP resolution, F2.4 aperture, 0.2m minimum object distance, and 5.3mm back focal length in a compact M12×0.5 configuration. Explore our M12 Lenses for additional compact wide-angle optical solutions.

Product Core Highlights

• 160° Ultra-Wide FOV: The 2.5mm focal length provides 160° diagonal, 125° horizontal, and 90° vertical coverage for broad-area imaging.
• 5MP Imaging: Supports 5MP camera systems requiring wider scene coverage while maintaining detailed image capture.
• 1/2.5″ Image Format: Designed for larger sensor coverage than many compact M12 wide-angle configurations.
• Compact M12×0.5 Mount: Provides a practical mechanical interface for embedded camera modules and space-constrained imaging equipment.
• 0.2m Minimum Object Distance: Supports near-field wide-area imaging where subjects or surrounding structures need to be captured at relatively short distances.

M12 Fisheye Lens Applications

Core Application Scenes

This 2.5mm M12 fisheye lens is designed for applications where maximum scene coverage is more important than low geometric distortion. Its 160° diagonal FOV allows a compact camera to capture a very broad area, making it suitable for monitoring environments where minimizing blind zones is a priority.

Designed for wide-area monitoring and environmental perception applications, this lens can be integrated into compact security cameras, indoor monitoring systems, robotics vision modules, and embedded imaging devices.

Typical applications include:

• Wide-area indoor surveillance
• Smart security monitoring
• Indoor environmental perception
• Robotics scene awareness
• Indoor navigation
• Smart home cameras
• IoT vision systems
• Compact embedded cameras
• Panoramic and wide-area monitoring
• Near-field environmental sensing

The <-74% distortion specification indicates that the lens is optimized for extreme wide-angle coverage rather than geometrically accurate imaging. It is therefore better suited to scene awareness, monitoring, and perception than precision measurement or dimensional inspection. For applications where distortion control is a primary requirement, see our Low Distortion Lens range.

Compatible Devices

The lens can be integrated into:

• 5MP M12 camera modules
• 1/2.5″ camera systems
• Smart security cameras
• Indoor monitoring cameras
• Robotics perception modules
• IoT imaging devices
• Embedded wide-angle cameras
• Environmental sensing cameras
• Compact surveillance devices

Frequently Asked Questions

Q: What is the field of view of this 2.5mm M12 lens?
A: The lens provides a 160° diagonal FOV, 125° horizontal FOV, and 90° vertical FOV, making it suitable for extremely wide-area imaging.

Q: Is this lens considered a fisheye lens?
A: Yes. Its 160° diagonal FOV and strong wide-angle characteristics place it in the ultra-wide/fisheye lens category, particularly for applications requiring extensive scene coverage.

Q: Is this a low-distortion lens?
A: No. The specified distortion is below -74%, so the lens should be selected for wide-area coverage rather than applications requiring accurate geometric reproduction or precision measurement.

Q: What sensor size is this M12 lens designed for?
A: The specified image format is 1/2.5″, making it suitable for camera systems using a 1/2.5″ image sensor format.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.2m, allowing the lens to capture relatively close subjects while maintaining its wide field of view.

Q: What does the 6G+IRCF construction mean?
A: The optical structure consists of six glass elements plus an IR cut filter. IRCF should not be interpreted as IR correction; it indicates an IR cut filtering component rather than an IR-corrected optical design.

Q: Can this lens be used for machine vision?
A: It can be considered for machine vision systems focused on environmental perception, scene coverage, or object presence detection. However, its high distortion makes it unsuitable for applications that require precise dimensional measurement or highly accurate geometric imaging.

Q: Can TOWIN customize this M12 fisheye lens?
A: TOWIN can evaluate OEM and customized optical requirements including focal length, sensor compatibility, field of view, mechanical dimensions, and other project-specific parameters. Contact our engineering team for a customized optical solution.
