Wide Angle Lens – CCL158018MPF

CCL158018MPF is 1/5.8″ 1.8mm High-Quality wide angle lens with Built-In Filter, F2.5 M7x0.35 mount lens, 2 Megapixel resolution CCTV lens.

1.8mm M7 Wide Angle Miniature Lens

This 1.8mm M7 wide angle lens is a compact fixed-focal-length optical solution designed for small-format camera modules requiring broad scene coverage in a limited installation space. With a 120° diagonal FOV, 92° horizontal FOV, M7×0.35 mount, and 1/5.8″ image format, it is well suited for compact embedded cameras, monitoring modules, and space-constrained vision devices.

The lens combines a 5G optical construction with an IR cut filter and manual focus adjustment, providing a practical balance between compact mechanical dimensions and stable 2-megapixel imaging performance.

M7 Wide Angle Lens Core Highlights at a Glance

• 1.8mm ultra-short focal length for broad scene coverage in compact camera systems.
• 92° horizontal FOV helps capture a wider area from a short working distance.
• 2MP optical performance matched to 1/5.8″ image sensors.
• M7×0.35 miniature mount supports compact and space-constrained camera designs.
• 5G optical construction with IR cut provides a practical solution for visible-light imaging modules.

M7 Wide Angle Lens Applications

Core Application Scenes

This 1.8mm M7 wide angle miniature lens is designed for applications where camera size and field coverage are both important. Its short 12.15mm T.T.L. and M7×0.35 mount make it particularly suitable for compact camera modules installed inside small electronic devices, monitoring equipment, and embedded vision products.

With a 92° horizontal field of view, the lens can cover a relatively broad scene without requiring a long installation distance. This makes it useful for compact indoor monitoring cameras, smart device cameras, embedded vision modules, access monitoring equipment, and small inspection or observation systems where a conventional C-Mount or CS-Mount lens would be unnecessarily large.

The manual focus design allows the optical system to be adjusted during camera assembly or production setup, while the fixed F2.5 aperture provides a straightforward configuration for applications with relatively controlled lighting conditions.

Compatible Device List

• Compact Camera Modules: Suitable for small camera boards using 1/5.8″ sensors where a short optical package and wide viewing coverage are required.
• Embedded Vision Devices: The M7×0.35 miniature mount is suitable for compact embedded imaging systems with strict mechanical space limitations.
• Indoor Monitoring Equipment: The 92° horizontal FOV helps cover entrance areas, equipment surroundings, counters, or other relatively close-range scenes.
• Smart Electronics: Its compact optical structure can be integrated into smart devices and electronic equipment requiring a small camera module.
• OEM Camera Modules: The fixed focal design and manual focus configuration provide a practical optical platform for customized camera assemblies.

Designed for compact embedded camera and wide-angle monitoring applications where small optical dimensions and broad scene coverage are required.

Optical Integration Considerations

When integrating this lens into a camera module, the sensor format, required field of view, mechanical clearance, and target working distance should be evaluated together. The sensor guide can help verify sensor and image-circle compatibility, while the FOV Calculator can be used to estimate scene coverage for a specific installation distance.

For applications requiring a different focal length or field of view, the lens selection guide provides additional guidance for matching lens characteristics with camera requirements.

Why Choose an M7 Miniature Wide Angle Lens?

Miniature camera systems often need to balance three competing requirements: physical size, field coverage, and image quality. A conventional industrial lens may provide greater optical flexibility but can be too large for embedded camera designs. This M7 lens addresses that mechanical constraint with a compact M7×0.35 interface and 12.15mm T.T.L., while the 1.8mm focal length provides a broad viewing angle.

For projects requiring a larger range of miniature optical solutions, the Other Mount Lenses category provides access to additional small-format and special-mount lens options.

For broader embedded M12 optical requirements, users can also explore the M12 Lenses product range, which provides additional compact lens configurations for embedded vision systems.

Frequently Asked Questions

Q: What sensor size is this M7 lens designed for?

A: This lens is specified for a 1/5.8″ image format and provides 2-megapixel optical performance for compatible camera modules.

Q: What is the field of view of the 1.8mm M7 lens?

A: The lens provides a 120° diagonal FOV, 92° horizontal FOV, and 65° vertical FOV, making it suitable for wide-angle close-range imaging.

Q: Is this an M7 fixed focal lens?

A: Yes. The lens uses a 1.8mm fixed focal length and fixed zoom configuration. Focus is manually adjustable during camera assembly or installation.

Q: What type of mount does this lens use?

A: It uses an M7×0.35 mount, which is commonly used for compact miniature camera modules and space-constrained optical assemblies.

Q: Is this lens suitable for wide-angle camera applications?

A: Yes. Its 92° horizontal and 120° diagonal FOV make it a practical choice for compact wide-angle camera systems that need broad scene coverage.

Q: Does this lens have IR correction?

A: The specification lists a 5G + IR cut optical construction. The IR cut filter cuts unwanted infrared wavelengths for visible‑light imaging. Do not confuse this feature with an IR‑corrected optical design.

Q: What is the total track length of this M7 lens?

A: The specified T.T.L. is 12.15mm, making the lens suitable for compact camera assemblies where optical package length is an important design constraint.

Q: Can this M7 lens be customized for an OEM camera module?

A: For OEM projects, you can evaluate optical and mechanical requirements against the target sensor, FOV, mounting structure, housing limitations and imaging environment. For project-specific requirements, contact the Towin optical engineering team for further evaluation.
