Wide Angle Lens – CCL13045MP

CCL13045MP 4.5mm fixed focal M12 wide angle lens with 78° FOV

4.5mm Megapixel M12 Wide Angle Fixed Focal Lens

This 4.5mm M12 wide angle lens is designed for compact camera modules requiring a balanced field of view, megapixel imaging, and a compact M12 × 0.5 interface. With a 78° diagonal FOV, 63° horizontal FOV, F2.2 aperture, and 4G + IR Cut optical construction, this fixed focal lens is suitable for indoor security cameras, smart monitoring devices, IoT camera modules, and other embedded imaging systems.

M12 Wide Angle Lens Core Highlights

• Balanced 63° Horizontal FOV — The 4.5 mm focal length delivers a 63° horizontal FOV, balancing coverage and perspective against ultra‑wide M12 lenses.
• Megapixel Imaging for Everyday Camera Systems — The megapixel optical configuration is designed for camera modules that require clear image reproduction for monitoring, observation, and embedded imaging applications.
• F2.2 Fixed Aperture for Stable Integration — The F2.2 aperture and fixed iris provide a straightforward optical configuration for dedicated camera products, avoiding the mechanical complexity of adjustable iris systems.
• 0.2m M.O.D. for Close-Range Monitoring — With a minimum object distance of 0.2m, the lens can be positioned relatively close to the monitored subject, making it practical for indoor monitoring, entrance cameras, and compact smart devices.
• 4G + IR Cut Optical Construction — The four‑glass‑element optics deliver megapixel performance, and the built‑in IR‑cut filter suits visible‑light camera systems.

M12 Wide Angle Lens Applications

This 4.5mm M12 fixed focal lens is intended for applications that need moderate wide-angle coverage rather than an extremely wide viewing angle. Its 63° horizontal FOV provides a useful balance between scene coverage and perspective control, while the 0.2m M.O.D. supports relatively close installation positions.

• Indoor Security Cameras — The 63° horizontal FOV covers rooms, entrances, offices and retail spaces without excessive wide‑angle distortion.
• Smart Monitoring Devices — The compact M12 × 0.5 mount makes the lens suitable for embedded monitoring products that require a fixed field of view and a small optical interface.
• Entrance and Access Monitoring — The 0.2m minimum object distance allows the camera to be positioned relatively close to doors, access points, counters, and other monitored areas while maintaining useful image coverage.
• IoT Camera Modules — The fixed focal design simplifies integration into smart home and connected devices where the camera viewing angle is predetermined during product development.
• Compact Embedded Imaging Systems — The combination of 4.5mm focal length, megapixel imaging, and M12 mounting provides a practical optical solution for equipment requiring more controlled coverage than ultra-wide lenses.

Compatible equipment: This lens is designed for compatible 1/3″ CMOS camera modules using an M12 × 0.5 interface, including compact IP camera modules, indoor security cameras, smart monitoring devices, IoT camera modules, entrance monitoring cameras, and embedded imaging equipment.

Frequently Asked Questions

• Q: What type of lens is this?
  A: This is a 4.5mm M12 fixed focal wide angle lens designed for 1/3″ camera sensors. It provides a 78° diagonal FOV and 63° horizontal FOV for balanced wide-angle coverage.
• Q: What is the field of view of this 4.5mm M12 lens?
  A: The lens provides a 78° diagonal FOV, 63° horizontal FOV, and 47° vertical FOV, making it suitable for moderate wide-angle monitoring applications.
• Q: What sensor size is compatible with this lens?
  A: The specified image format is 1/3″, so the lens is designed for compatible 1/3″ CMOS image sensors and camera modules.
• Q: Is this an M12 fixed focal lens?
  A: Yes. The lens uses an M12 × 0.5 mount and has a fixed 4.5mm focal length, fixed iris, and fixed zoom configuration.
• Q: What is the advantage of a 4.5mm focal length compared with a 2.1mm M12 lens?
  A: The longer 4.5mm focal length provides a narrower and more controlled field of view, which can be preferable when excessive scene coverage or extreme wide-angle perspective is not required.
• Q: What is the minimum object distance of this lens?
  A: The specified M.O.D. is 0.2m, allowing the lens to capture relatively close subjects and making it suitable for short-range monitoring applications.
• Q: Does this lens have IR correction?
  A: This model includes an IR Cut configuration, which is different from an IR Corrected optical design. It should therefore be classified as an IR Cut lens rather than an IR Corrected Lens.
• Q: Can TOWIN customize this M12 lens?
  A: TOWIN can support customized optical solutions based on sensor format, focal length, field of view, aperture, mounting interface, and application requirements. Customers can contact TOWIN to discuss their specific project.
