Wide Angle Lens – CCL13036MPR2

CCL13036MPR2 M12 S-mount wide angle 3.6mm CCTV board lens with IR corrected.

3.6mm 3MP M12 IR Corrected Wide Angle Lens

This 3.6mm 3MP M12 wide angle lens is designed for compact camera systems that require a wider field of view together with stable imaging across visible and infrared wavelengths. With a 104° diagonal FOV, 75° horizontal FOV, and 58° vertical FOV on a 1/3″ sensor, the lens provides broad scene coverage while maintaining a more moderate wide-angle configuration than ultra-wide lenses. Its 3MP resolution, fixed F2.0 aperture, and IR-corrected optical design make it suitable for compact security cameras, day-and-night monitoring systems, and embedded imaging devices.

The M12X0.5 mount, 22.4mm total track length, and 7.1mm back focal length support integration into compact camera assemblies. Manual focus allows the optical position to be adjusted during installation, while the fixed focal length and fixed iris provide a straightforward configuration for production camera modules. For additional compact optical options, TOWIN provides a selection of M12 lenses and wide angle lenses.

Optical & Mechanical Configuration

• 1/3″ Image Format — Designed for compact camera modules using 1/3″ CMOS sensors.
• 3.6mm Focal Length — Provides a practical wide-angle configuration for cameras requiring broader coverage without the extreme distortion associated with ultra-short focal lengths.
• 104° Diagonal FOV — Covers a wide scene while maintaining a more moderate field of view for general-purpose monitoring.
• 75° Horizontal FOV — Provides useful horizontal coverage for entrances, rooms, corridors, and other monitored areas.
• 3MP Resolution — Supports higher image detail than standard 2MP camera configurations.
• F2.0 Aperture — Provides a fixed, relatively bright optical configuration for compact imaging equipment.
• M12X0.5 Mount — Enables straightforward integration into compact camera modules and embedded optical systems.
• IR Corrected — Helps maintain consistent focus when the imaging system operates across visible and infrared wavelengths.
• Manual Focus — Allows focus adjustment during camera assembly or installation.
• Fixed Iris & Fixed Zoom — Simplifies optical integration for camera systems designed around a fixed focal length.
• 0.3m M.O.D. — Supports applications where the monitored subject may be relatively close to the camera.
• 7.1mm B.F.L. — Provides a defined back focal position for camera module optical integration.

M12 IR Corrected Wide Angle Lens Applications

The combination of 3.6mm focal length, 104° diagonal FOV, 3MP resolution, and IR correction makes this lens suitable for camera systems that need broad scene coverage but do not require the extreme viewing angle of a fisheye or ultra-wide lens.

Core Applications

• Day-and-Night Security Cameras — IR correction supports camera systems that switch between visible-light and infrared illumination, helping maintain focus consistency between operating modes.
• Indoor Surveillance — The 104° diagonal FOV provides broad coverage for rooms, corridors, entrances, and other indoor areas.
• Entrance Monitoring — The wide-angle configuration helps capture approaching subjects across a wider horizontal area from a relatively compact mounting position.
• Smart Security Devices — The combination of 3MP resolution, M12 mounting, and IR correction is suitable for embedded security camera designs.
• Compact IP Camera Modules — The fixed focal configuration simplifies integration into camera modules designed around a predefined field of view.
• Embedded IoT Cameras — The M12 interface supports integration into compact connected imaging equipment where optical size and installation flexibility are important.
• Close-Range Monitoring — With a 0.3m minimum object distance, the lens can be used where subjects are positioned relatively close to the camera.
