Fisheye Lens – CCL12015MP

CCL12015MP Fisheye CCTV HD lens IR corrected 1/2.3″ Φ4.5 M12 lens 185° 8MP F2.5 security surveillance

1.5mm 8MP M12 185° Fisheye IR Corrected Lens

This 1.5mm M12 Fisheye lens is designed for compact imaging systems that require high-resolution 8MP imaging and an exceptionally wide 185° field of view. With a Φ4.5mm image circle, F2.5 fixed aperture, and 1.5mm focal length, the lens provides extensive scene coverage for panoramic, surround-view, security, robotics, and embedded vision applications. Its 185° diagonal, horizontal, and vertical FOV enables near-panoramic image capture from a compact camera position, while the IR-corrected optical design helps maintain consistent imaging performance across visible and near-infrared wavelengths. The M12x0.5 mount, 0.3m minimum object distance, and compact Φ28 × 24mm dimensions make this lens suitable for integration into space-constrained camera modules.

M12 Fisheye Lens Applications & Compatible Devices

Panoramic and 360°-Class Imaging

With a 185° FOV across diagonal, horizontal, and vertical directions, this lens is well suited to panoramic imaging systems that need to capture a very large surrounding area from a single camera position. The 1.5mm focal length provides substantially wider coverage than conventional Fisheye lenses.

Compatible devices:

• Panoramic camera modules
• 360° vision systems
• Wide-area monitoring cameras
• Compact panoramic cameras
• Embedded panoramic imaging devices

For systems requiring extremely broad optical coverage, this lens can complement TOWIN’s Fisheye Lens portfolio.

Smart Security & Surveillance

The 185° viewing angle can help reduce blind spots in security monitoring applications where a single compact camera needs to observe a large area. The 8MP resolution provides additional image detail for scene monitoring, while IR correction supports applications involving near-infrared illumination.

Compatible devices:

• Smart security cameras
• Wide-area surveillance cameras
• Indoor monitoring cameras
• IoT security cameras
• Compact network camera modules

• Smart IoT imaging devices
• Near-infrared vision systems

For systems where wavelength performance is important, TOWIN’s Optical Design resources provide additional guidance for lens selection.

Optical Design & Imaging Characteristics

The 1.5mm focal length and 185° FOV define this lens as an extremely Fisheye optical solution. The specified -104% distortion is characteristic of an ultra-wide/fisheye-style projection and should be considered when designing image-processing and geometric correction algorithms.

Unlike a conventional low-distortion lens, this optical configuration prioritizes maximum scene coverage. Therefore, it is particularly suitable when capturing a very large field of view is more important than maintaining rectilinear geometry directly in the raw image.

The IR-corrected design is another important characteristic. It helps the lens maintain optical focus behavior when the imaging system operates across visible and near-infrared wavelengths, which can be valuable for smart cameras and IR-assisted vision systems.

Lens Selection Considerations

When evaluating this 1.5mm 8MP M12 lens, consider the following factors:

• Image circle: Φ4.5mm.
• Resolution: 8MP.
• Field of view: 185° D/H/V.
• Distortion: -104%, requiring consideration of the intended projection and image correction method.
• Mount: M12x0.5.
• Aperture: Fixed F2.5.
• Minimum object distance: 0.3m.
• IR performance: IR corrected.
• Mechanical size: Φ28 × 24mm.
