Fisheye Lens – C02211828M10

C02211828M10 is 2.2mm fixed-zoom C-Mount Fisheye Lenses, 1/1.8″ C-Mount manual iris lens, F2.8~16, high resolution 10-Megapixel Industrial Lens.

The extremely wide 180° viewing angle makes this lens particularly suitable for applications where conventional lenses cannot cover the required scene. Engineers can evaluate sensor size, focal length, and required coverage with the FOV Calculator when designing the imaging system.

1/1.8″ 10MP 2.2mm 180° C-Mount Fisheye Lens

This 1/1.8-inch 10MP 2.2mm C-Mount fisheye lens delivers an ultra-wide 180° field of view, making it ideal for machine vision systems that need to capture an exceptionally large scene with a single camera. Its fixed 2.2mm focal length, 10MP resolution, and compact 5mm minimum object distance provide a specialized optical solution for panoramic and close-range industrial imaging.

Designed for 1/1.8-inch sensors, this 180° fisheye machine vision lens combines a manual F2.8–16 aperture with a fixed-focus configuration, making it suitable for applications requiring maximum scene coverage from a compact camera position.

C-Mount Fisheye Lens Applications

Core Application Scenes

This 180° C-Mount fisheye lens is designed for imaging systems where maximum scene coverage is more important than conventional rectilinear image geometry. Its 180° field of view allows a single camera to observe a very large surrounding area, reducing blind spots and potentially reducing the number of cameras required in certain monitoring or inspection configurations.

In industrial machine vision, the lens can be used for applications that require broad environmental awareness rather than conventional dimensional measurement. For example, it can monitor an entire work area, observe equipment surroundings, or provide wide-area visual feedback to an automated system.

The extremely short 5mm minimum object distance also makes this lens suitable for specialized close-range imaging configurations. You can place it very close to a target when you need a large viewing angle within a compact mechanical installation.

For robotics vision, the 180° FOV can provide wide environmental awareness around a robotic platform, helping capture objects and surrounding activity that may fall outside the field of conventional narrow-FOV lenses. It can complement rather than replace directional machine vision cameras used for detailed inspection.

The lens also suits panoramic observation, compact embedded vision devices, security monitoring prototypes, and experimental vision systems that demand an extremely wide optical field.

For engineers developing complete Machine Vision Solutions or Robotics Vision Solutions, this fisheye configuration provides a specialized option for wide-area visual perception.

Compatible Device List

• 1/1.8-inch Industrial Cameras: Designed for compatible C-Mount cameras using 1/1.8-inch sensors.
• Machine Vision Cameras: Suitable for wide-area visual monitoring, environmental observation, and specialized inspection systems.
• Robotic Vision Platforms: Can provide broad peripheral visibility for robotic systems and autonomous equipment.
• Panoramic Imaging Systems: The 180° FOV is suitable for panoramic and hemispherical imaging configurations.

Fisheye lenses intentionally adopt a highly curved optical projection to deliver ultra-wide coverage, so engineers evaluate them differently from standard low-distortion machine vision lenses. Engineers should consider the required projection, image-processing method, and target coverage during system design.

Frequently Asked Questions

Q: Is this a fisheye lens?
A: Yes. The 2.2mm focal length combined with a 180° field of view is characteristic of a fisheye optical design. It is intended for extremely wide scene coverage rather than conventional rectilinear imaging.

Q: What is the field of view of this 2.2mm lens?
A: The supplied specification lists a 180° field of view at Φ8. The exact image projection and coverage should be evaluated according to the camera sensor and mechanical installation.

Q: What sensor size is this fisheye lens designed for?
A: The lens is designed for a 1/1.8-inch image format and uses a C-Mount interface.

Q: Is this lens suitable for machine vision?
A: Yes. The 10MP resolution, 1/1.8-inch image format, and C-Mount interface make it suitable for specialized machine vision systems requiring extremely wide scene coverage.

Q: What is the minimum object distance?
A: The specified M.O.D. is 5mm. This extremely short minimum object distance allows the lens to be installed very close to the imaging target in suitable applications.

Q: Is the focal length fixed?
A: Yes. The supplied specification lists Zoom as Fixed, with a 2.2mm focal length. This configuration is intended for applications requiring a fixed ultra-wide-angle optical setup.

Q: Can the aperture be adjusted?
A: Yes. The lens uses a manual iris with an aperture range from F2.8 to F16, allowing users to adjust exposure and depth of field according to the imaging environment.

Q: Can this lens be used for panoramic imaging?
A: Yes. Its 180° FOV makes it particularly suitable for panoramic, hemispherical, wide-area monitoring, and environmental perception applications where a single camera needs to cover a very large viewing area.
