M12 Lenses – CCL117049MP

CCL117049MP is 4.9mm High-Resolution Low distortion lens, 1/1.7″ M12/S mount lens, 12-Megapixel wide-angle lens, F2.2 aperture IR corrected CCTV lens.

4.9mm M12 12MP Wide Angle IR Corrected Lens

This 4.9mm M12 wide angle lens is designed for 1/1.7″ high-resolution image sensors such as the Sony IMX226, delivering up to 12MP resolution and a 96° diagonal field of view. With an IR-corrected optical design, F2.2 aperture, and compact M12 × 0.5 mount, it is well suited to wide-area embedded vision, industrial imaging, robotics, and intelligent camera systems.

When selecting a wide-angle lens for a high-resolution sensor, sensor dimensions and image coverage should be evaluated together. The Sensor Guide explains key sensor-format considerations, while the Lens Selection Guide provides additional guidance for matching lens specifications to an imaging system.

Product Core Highlights

• 4.9mm wide-angle focal length for broad scene coverage.
• 12MP resolution support for high-detail imaging.
• 96° diagonal FOV on the specified IMX226 configuration.
• IR-corrected optical design for visible and near-infrared imaging.
• M12 × 0.5 compact mount for embedded vision integration.

The lens is part of Towin’s M12 Lenses range and combines a short focal length with a high-resolution sensor format, making it suitable for applications where a camera needs to capture a broad scene from a relatively compact installation position.

M12 Wide Angle IR Corrected Lens Applications

Core Application Scenes

This 4.9mm M12 industrial lens is designed for wide-area imaging where the camera needs to capture a large portion of the surrounding scene. With a 96° diagonal and 83° horizontal FOV on the specified IMX226 configuration, it provides substantially broader coverage than conventional medium- and long-focal-length machine vision lenses.

The lens is particularly suitable for robotics and embedded vision systems where a compact camera must observe objects, workspaces, or movement over a broad area. In robotic applications, the wide FOV can help provide visual context for navigation, object detection, workspace monitoring, and position awareness.

Its 12MP resolution is also valuable when the system needs both broad coverage and image detail. Instead of using a lower-resolution sensor simply to achieve a wide scene view, this configuration can combine high pixel count with a short 4.9mm focal length for applications requiring detailed analysis across a relatively large image area.

The IR-corrected design provides an additional advantage for systems that use near-infrared illumination or operate across different wavelengths. This makes the lens suitable for intelligent camera platforms that may require more consistent optical behavior between visible-light and NIR imaging conditions.

The TV distortion specification of below -8% indicates that this lens is designed primarily around wide-area coverage rather than low-distortion measurement. It is therefore better suited to scene awareness, monitoring, recognition, and wide-area visual perception than applications requiring highly accurate geometric measurement.

For engineers evaluating the relationship between focal length, sensor size, and viewing coverage, the FOV Calculator can be used to estimate the field of view required for a specific camera installation.

Designed for high-resolution wide-area imaging, embedded vision, robotic perception, and intelligent camera applications.
