Fisheye Lens – S2918521F

S2918521F is Fisheye CCTV Lens with Built-In IR Filter, 2-Megapixel 1.3mm M12 Mount, 185° Diagonal Field of View, F2.1 Aperture for Security Surveillance.

1.3mm M12 185° Fisheye Lens for IMX462

This 1.3mm M12 fisheye lens is designed for the Sony IMX462 sensor, delivering an extremely wide 185° field of view across the diagonal, horizontal, and vertical directions. With 2MP resolution, F2.1 aperture, M12 × 0.5 mounting, and a compact 16.93mm total optical length, it is designed for wide-area imaging where maximum scene coverage is required.

The lens is particularly suitable for compact security cameras, panoramic imaging modules, robotics perception, and embedded vision systems requiring an ultra-wide field of view from a small optical package.

1.3mm M12 185° Fisheye Lens Applications

Core Application Scenes

Ultra-Wide Security Monitoring

The 185° field of view allows the camera to observe a very broad area from a single installation point. This makes the lens suitable for security systems where wide scene awareness and reduced blind areas are important.

IMX462-Based Security Cameras

The lens is specifically specified for the IMX462 sensor, making it suitable for camera designs built around this 2MP image sensor. The optical configuration can provide extremely broad coverage for compact security camera architectures.

Panoramic Imaging

The equal 185° diagonal, horizontal, and vertical FOV provides extremely broad angular coverage. This makes the lens suitable for panoramic and surround-scene imaging where conventional rectilinear lenses cannot provide sufficient coverage.

Robotics and Environmental Perception

The ultra-wide FOV can provide a large visual awareness range for robotic systems. It can support environmental observation, obstacle awareness, and surrounding-scene perception where a broad angular view is required.

Embedded Wide-Angle Vision

The M12 × 0.5 mount provides a compact mechanical interface for embedded camera modules. The lens can be integrated into OEM vision devices requiring extreme wide-angle coverage without using a large industrial lens assembly.

Designed for IMX462-based ultra-wide security, panoramic imaging, robotics perception, and compact embedded vision applications.

Frequently Asked Questions

Q: What sensor is this 1.3mm M12 fisheye lens designed for?
A: The lens is specified for the Sony IMX462 sensor, with a maximum image format of Φ2.9mm.

Q: What is the field of view on IMX462?
A: The specified FOV is 185° diagonal, 185° horizontal, and 185° vertical on the IMX462 sensor.

Q: Is this an M12 fisheye lens?
A: Yes. It uses an M12 × 0.5 mount and provides a 185° field of view, making it an ultra-wide fisheye lens.

Q: What is the resolution of this lens?
A: The lens is specified for 2MP resolution and is designed around the IMX462 sensor.

Q: What does F(θ) distortion mean?
A: F(θ) distortion describes the deviation of the lens’s image projection from an ideal angular relationship. It is particularly relevant to fisheye and ultra-wide optical systems and should not be compared directly with conventional TV distortion.

Q: Is this a low distortion lens?
A: No. The lens is designed for an extremely wide 185° field of view. Its F(θ) distortion specification reflects the fisheye projection rather than a low-distortion optical design.

Q: Does IRCF mean the lens is IR corrected?
A: Not necessarily. IRCF indicates an infrared-related optical component, but it does not by itself confirm that the lens has been optically corrected for infrared wavelengths.

Q: What is the minimum object distance?
A: The specified M.O.D. is 0.2m, or 200mm.
