Fisheye Lens – S6819020

S6819020 is 1.9mm M12 8MP fisheye lens with 181° FOV, F2.0 aperture and IR correction for panoramic, robotic and day-night vision.

1.9mm M12 Fisheye Lens

This 1.9mm M12 fisheye lens delivers an ultra-wide 181° diagonal field of view with 8MP imaging performance, making it suitable for compact cameras that need to capture an exceptionally broad scene. Its IR-corrected optical design supports both visible-light and near-infrared imaging, providing greater flexibility for day-and-night vision applications.

With an M12×0.5 mount, F2.0 aperture, 0.2m minimum object distance, and fixed-focus configuration, this wide angle lens is designed for compact embedded cameras, panoramic vision systems, robotics, security imaging, and other applications where maximum scene coverage is more important than low geometric distortion.

Applications & Compatible Devices

Core Application Scenes

This 1.9mm M12 fisheye lens is designed for vision systems where an extremely wide field of view is essential. Its 181° diagonal FOV allows a single camera to monitor a very large area, reducing blind spots in compact imaging systems.

For robotic platforms, the lens can provide broad environmental awareness for navigation, obstacle observation, and visual localization. Its compact M12 form factor also makes it suitable for embedded cameras installed where optical space is limited. For related embedded optical configurations, see the M12 Lenses range.

The combination of 8MP resolution and ultra-wide coverage is also useful for panoramic security cameras, indoor monitoring systems, compact mobile cameras, and surround-view imaging where comprehensive scene capture is prioritized over rectilinear image geometry.

Its IR-corrected design makes the lens particularly useful for systems that operate under changing illumination. Cameras can maintain more consistent focus when switching between daytime visible-light imaging and nighttime near-infrared illumination. This makes it a practical optical component for selected Smart Security and embedded day-and-night vision systems.

Designed for ultra-wide-angle panoramic vision, robotic perception, and day-and-night embedded imaging applications.

Compatible Device List

• Embedded Vision Cameras: Suitable for compact camera modules using an M12×0.5 interface where maximum scene coverage is required.
• Robotics Vision Systems: Can be integrated into mobile robots, autonomous platforms, and compact robotic cameras for wide-area environmental perception. Related system requirements can be explored through Robotics Vision.
• Panoramic Security Cameras: The ultra-wide FOV helps a single camera monitor large indoor areas, entrances, corridors, or other spaces where reducing blind spots is important.
• Mobile & Compact Imaging Devices: The small M12 mounting format is suitable for embedded imaging equipment with restricted mechanical space.
• Day & Night Vision Cameras: IR correction supports applications that combine visible-light imaging with near-infrared illumination.
• Wide-Area Inspection Systems: The lens can be considered for machine vision setups that require broad scene acquisition rather than precision geometric measurement.

Optical Design Considerations

The optical distortion of this lens is specified at < -95%, which is characteristic of an extreme fisheye optical configuration. This design prioritizes exceptionally wide scene coverage rather than straight-line reproduction.

For applications where geometric accuracy and dimensional measurement are critical, a low-distortion optical design may be more appropriate. Users selecting a lens for machine vision should also consider sensor format, working distance, field of view, and image requirements. The Lens Selection Guide provides additional guidance for matching lens characteristics to a vision system.

For projects requiring precise coverage calculations, the FOV Calculator can help evaluate field-of-view requirements before lens selection.
