Fisheye Lens – S02412514820F

S02412514820F – 1/2.5″ 2.4mm fisheye lens with Built-In Filter, M12-Mount Lenses with Low F-number (Fast Lenses), F2.0 218° 5-Megapixel lens.

5MP 2.4mm M12 218° Ultra-Wide Fisheye Lens

This 5MP 2.4mm M12 fisheye lens is designed for camera systems that require an exceptionally wide field of view from a compact optical package. With a 218° diagonal FOV on a 1/2.5″ MT9P031 sensor, this ultra-wide angle lens is well suited for panoramic monitoring, compact embedded cameras, robotics perception, smart security, and other applications where maximum scene coverage is a priority.

Featuring an F2.0 aperture, M12×0.5 mount, 0.2m minimum object distance, and 7G+IRCF optical construction, the lens provides a practical solution for wide-area imaging systems. For additional compact optical options, explore TOWIN’s M12 lens range.

Product Core Highlights

• 218° ultra-wide diagonal FOV: The 2.4mm focal length provides an exceptionally broad 218° diagonal field of view for applications requiring maximum scene coverage.
• 5MP imaging performance: Designed for high-resolution wide-area imaging with the MT9P031 sensor format.
• Ultra-wide fisheye optical design: The extreme FOV makes this lens suitable for panoramic and environmental perception applications where conventional wide-angle lenses cannot provide sufficient coverage.
• Compact M12×0.5 mount: Supports compact embedded camera architectures and space-constrained imaging modules.
• Short 3.99mm BFL: The short back focal length provides flexibility for compact camera module integration.
• 0.2m minimum object distance: Supports relatively close-range wide-area imaging where the camera needs to observe nearby surroundings.

For applications where ultra-wide coverage is more important than geometric accuracy, this lens is a strong alternative to conventional wide-angle optics. See TOWIN’s fisheye lens collection for other ultra-wide optical configurations.

M12 Fisheye Lens Applications

Core Application Scenes

The combination of 2.4mm focal length, 218° diagonal FOV, 5MP resolution, and 0.2m M.O.D. makes this lens particularly suitable for imaging systems that need to capture a very large surrounding area from a relatively short distance.

Designed for panoramic and wide-area monitoring applications. The 218° diagonal FOV can provide extremely broad scene coverage for indoor monitoring, room awareness, entrances, compact surveillance devices, and other environments where minimizing blind areas is a primary requirement.

The lens is also suitable for robotics environmental perception, where a very wide viewing angle can help a robot observe nearby surroundings, obstacles, and movement around the camera. Its 2.4mm focal length allows the camera system to capture a much larger surrounding scene than a conventional standard or moderate wide-angle lens.

For compact smart security devices, the M12×0.5 mount and short 3.99mm BFL provide useful integration flexibility. The lens can be considered for panoramic camera modules, embedded security cameras, indoor monitoring devices, and compact IoT vision products. Related applications can be explored through TOWIN’s smart security solutions.

The 0.2m M.O.D. also makes the lens useful for near-field environmental imaging, such as compact robotic platforms, indoor navigation equipment, smart home cameras, and embedded devices that need to observe objects or surroundings at relatively close distances.

Optical Consideration

This lens is specifically optimized for extreme field of view rather than low geometric distortion. With a specified distortion of less than -99%, it should be selected for applications where broad scene coverage and environmental awareness are more important than precise dimensional measurement or straight-line image reproduction.

For applications requiring controlled distortion, consider TOWIN’s low distortion lens range instead.

When evaluating the relationship between sensor size, focal length, and field of view, TOWIN’s FOV Calculator can also help with preliminary optical selection.

Frequently Asked Questions

Q: What is the maximum FOV of this 2.4mm M12 lens?
A: The lens provides a specified field of view of 218° diagonal, 148° horizontal, and 108° vertical when paired with the MT9P031 sensor on a 1/2.5″ image format.

Q: Is this a fisheye lens?
A: Yes. With a 218° diagonal FOV, this lens is designed as an extreme ultra-wide fisheye lens for applications requiring exceptionally broad scene coverage.

Q: Is this lens suitable for low-distortion machine vision?
A: No. Its extremely wide FOV is achieved through a highly distorted fisheye optical design, with a specified distortion of less than -99%. It is better suited to environmental awareness and panoramic imaging than precision measurement.

Q: What sensor is this lens designed for?
A: The specified configuration is designed for a 1/2.5″ image format and is listed with the MT9P031 sensor.

Q: What is the advantage of the 3.99mm BFL?
A: The short 3.99mm back focal length can simplify integration into compact camera modules where optical space behind the lens is limited.

Q: What applications are suitable for this M12 fisheye lens?
A: Typical applications include panoramic monitoring, smart security cameras, robotics environmental perception, indoor navigation, compact embedded cameras, IoT vision devices, and other wide-area imaging systems.

Q: Does the IRCF specification mean the lens is IR corrected?
A: No. IRCF indicates an IR cut filter configuration. This is not an IR-corrected optical design. Systems requiring infrared wavelength correction require a dedicated IR-corrected lens.

Q: Can TOWIN customize this type of M12 fisheye lens?
A: TOWIN can support customized optical solutions according to sensor format, focal length, field of view, mechanical interface, and application requirements. Contact the TOWIN engineering team to discuss a specific camera project.
