Wide Angle Lens – CCL128021MP

CCL128021MP 2.1mm 3MP M12 Wide Angle lens with 156° FOV

2.1mm 3MP M12 Wide Angle IR Corrected Lens

This 2.1mm M12 Wide Angle lens is designed for 1/2.8″ imaging sensors and provides an ultra-wide 156° diagonal field of view, 134° horizontal FOV, and 75° vertical FOV. With 3MP resolution, an F1.8 aperture, and a compact M12 × 0.5 mount, it is designed for camera systems that require extensive scene coverage from a compact optical package.

The IR corrected optical design helps maintain consistent imaging performance across visible and infrared illumination, making this lens a practical choice for day-and-night imaging systems. Manual focus and a 0.3m minimum object distance provide installation flexibility for applications requiring precise focus adjustment.

Applications & Compatible Devices

The combination of a 2.1mm focal length and 156° diagonal FOV makes this lens particularly suitable for applications where maximizing scene coverage is more important than maintaining a conventional perspective. The Wide Angle optical configuration can capture a broad surrounding area from a relatively short camera-to-scene distance, reducing blind spots in wide-area monitoring.

The IR corrected design further expands its suitability for imaging systems that operate under both visible and infrared illumination. This is especially useful for cameras designed for day-and-night monitoring, where changes in illumination wavelength can otherwise affect focus consistency.

Typical applications include:

• Wide-area security monitoring
• Indoor panoramic and near-panoramic camera modules
• Smart home security cameras
• IoT monitoring devices
• Embedded Wide Angle camera systems
• Day-and-night surveillance cameras
• Compact wide-area monitoring equipment
• Smart building and facility monitoring
• Short-range environmental observation systems

Compatible devices may include 1/2.8″ CMOS camera modules, compact security cameras, smart IoT cameras, embedded vision devices, Wide Angle camera modules, and M12-mount day-and-night imaging platforms.

For systems requiring very wide coverage, engineers should evaluate sensor format, FOV, installation distance, and the expected level of Wide Angle image deformation together. TOWIN’s Lens Selection Guide provides additional guidance for choosing a suitable lens, while the FOV Calculator can help estimate the required field of view for a specific camera installation.

Why Choose This 2.1mm M12 Wide Angle Lens?

The primary advantage of this lens is its 156° diagonal field of view in a compact M12 configuration. A conventional lens with a longer focal length would generally provide substantially narrower scene coverage, while this 2.1mm Wide Angle configuration is designed specifically for wide-area imaging.

The F1.8 aperture provides a useful balance between light collection and compact optical construction, while the IR corrected design makes the lens suitable for systems exposed to changing illumination conditions. The manual focus configuration allows installers to optimize focus according to the actual camera position and working distance.

The 7G optical construction and plastic barrel provide a compact lens architecture for integration into small camera modules. For application-specific optical requirements, mounting requirements, or customized lens development, Contact TOWIN for engineering support.
