Wide Angle Lens – CCL1270412MP – IMX290

CCL1270412MP is 4mm fixed iris 3-Megapixel wide-angle lens, 1/2.8″ CCTV lens IR corrected, F1.2 M12/S-Mount Lenses with Low F-number (Fast Lenses).

4mm F1.2 3MP M12 IR Corrected Wide Angle Lens

This 4mm M12 lens is designed for compact camera systems using the Sony IMX290 sensor, delivering a 94° horizontal field of view with 3MP resolution. With a fast F1.2 aperture, IR corrected optical design, and 0.15m minimum object distance, it provides wide-area imaging in space-constrained security and monitoring applications.

M12 IR Corrected Wide Angle Lens Core Highlights

• 4mm wide-angle coverage: Provides a 94° horizontal FOV and 112° diagonal FOV for broad scene coverage from a compact camera.
• Fast F1.2 aperture: Allows more light to reach the sensor, supporting brighter imaging in low-light indoor and surveillance environments.
• IR corrected optical design: Helps maintain focus consistency across visible and near-infrared wavelengths for day-and-night imaging systems.
• 3MP resolution support: Designed for 1/2.8″ sensors such as the Sony IMX290, balancing wide coverage with practical image detail.
• Compact M12 interface: The M12x0.5 mount makes the lens suitable for small camera modules where installation space is limited.

M12 IR Corrected Wide Angle Lens Applications

Core Application Scenes

This 4mm M12 wide angle lens is suitable for applications that require broad scene coverage without using a large C-mount or CS-mount optical assembly. The 94° horizontal FOV can cover a relatively large area from a short working distance, while the F1.2 aperture helps maintain useful image brightness in challenging lighting conditions.

Designed for compact security camera and day-and-night monitoring applications. The IR corrected optical design makes this lens particularly suitable for camera systems that switch between visible-light and near-infrared illumination. Its 0.15m minimum object distance also supports relatively close-range monitoring.

Compatible Device List

• Compact IP camera modules
• Miniature security cameras
• Indoor surveillance cameras
• Day-and-night monitoring cameras
• Low-light camera modules
• Compact video monitoring equipment
• Embedded camera systems using 1/2.8″ sensors
• Camera modules based on Sony IMX290-class sensors

Wide Angle Coverage for Compact Camera Systems

The 4mm focal length provides a wide viewing range without requiring a large optical assembly. With a 94° horizontal FOV, this lens can capture more of the surrounding scene than a standard narrow-FOV lens, making it useful for entrances, rooms, corridors, equipment areas, and other relatively close-range monitoring environments.

When selecting a wide-angle lens, field of view should be evaluated together with sensor size, mounting position, and target distance. TOWIN’s FOV Calculator can help estimate scene coverage, while the Sensor Guide provides additional information about sensor and lens matching.

IR Corrected Optical Performance

Unlike a standard optical design optimized only for visible light, an IR corrected lens is designed to reduce focus shift associated with different wavelengths. This makes the lens suitable for camera systems using IR illumination for nighttime or low-light monitoring.
