Wide Angle Lens – CCL175018MPR

CCL175018MPR is 1.8mm Lightweight Wide Angle Lens for Portability, F2.5 aperture M7x0.35 mount lens, 1/7.5″ 2-megapixel resolution CCTV lens.

1.8mm M7 2MP Wide Angle Miniature Lens

This 1.8mm M7 wide angle miniature lens is designed for compact camera modules requiring a wide field of view, 2MP imaging performance, and a small mechanical footprint. With a 1/7.5″ image format, 80° horizontal FOV, M7×0.35 mount, and 12.15mm TTL, it is suitable for embedded cameras, compact monitoring systems, IoT imaging devices, and other space-constrained applications.

M7 Miniature Wide Angle Lens Highlights at a Glance

• 1.8mm fixed focal length provides an 80° horizontal field of view for compact wide-area imaging.
• 2MP resolution supports image capture for embedded monitoring and general-purpose vision applications.
• M7×0.35 mount provides a compact mechanical interface for miniature camera modules.
• 12.15mm TTL helps accommodate applications where installation space is limited.
• F2.5 fixed aperture provides a practical balance between compact optical design and light collection.

M7 Miniature Wide Angle Lens Applications

Core Application Scenes

The combination of a 1.8mm focal length, 80° horizontal FOV, 2MP resolution, and M7×0.35 mount makes this lens suitable for applications where a compact lens needs to cover a relatively wide scene.

Typical applications include:

• Compact embedded camera modules
• IoT imaging devices
• Small-format monitoring cameras
• Indoor security and observation systems
• Smart home camera modules
• Robotics auxiliary cameras
• Compact vision sensors
• Space-constrained electronic devices
• Short-range wide-area imaging

The wide 95° diagonal field of view allows the lens to capture a relatively broad scene from a short working distance, while the 12.15mm TTL helps simplify integration into compact camera housings.

Designed for compact embedded imaging applications where wide scene coverage and a small M7 lens footprint are important.

Compatible Device List

This M7 miniature lens can be integrated into:

• M7-compatible compact camera modules
• Embedded monitoring cameras
• IoT vision devices
• Miniature security cameras
• Smart home imaging equipment
• Compact robotic imaging modules
• Custom OEM camera assemblies
• Small electronic imaging systems

The M7×0.35 mount and fixed-focus configuration make the lens particularly suitable for OEM camera designs where mechanical size and optical integration are key considerations.

Optical Performance and Selection Considerations

The 1.8mm focal length provides a wide field of view of 95° diagonal, 80° horizontal, and 60° vertical on the specified 1/7.5″ image format. This makes the lens useful when the camera needs to observe a relatively large area without increasing the physical size of the imaging module.

However, the specified TV distortion of less than -13.5% should be considered when selecting the lens for applications requiring geometrically accurate imaging. For applications such as measurement, dimensional inspection, or precision machine vision, a lower-distortion optical design may be more appropriate.

The fixed F2.5 aperture also provides a simple optical configuration for compact camera systems. Because the lens uses a manual focus mechanism, the final focus position should be adjusted according to the actual camera module, working distance, and target scene during integration.

Frequently Asked Questions

Q: What type of lens is the 1.8mm M7 lens?
A: It is a fixed focal length, wide angle miniature lens with an M7×0.35 mount. Its 1.8mm focal length provides a 95° diagonal and 80° horizontal field of view.

Q: What sensor format is this 1.8mm M7 lens designed for?
A: The specified image format is 1/7.5″. The actual imaging performance should be verified with the selected camera sensor and module.

Q: Is this lens suitable for 2MP camera modules?
A: Yes. The lens is specified for 2 Megapixel resolution and is suitable for compact camera modules requiring 2MP imaging performance.

Q: Is this lens a low distortion lens?
A: No. With TV distortion specified at less than -13.5%, it should be treated as a wide angle lens rather than a low distortion lens. Applications requiring accurate geometric reproduction should consider a lower-distortion optical design.

Q: What is the mount specification?
A: The lens uses an M7×0.35 mount, making it suitable for compatible miniature camera modules and compact embedded imaging systems.

Q: Can the focus be adjusted?
A: Yes. The lens uses manual focus, allowing the optical focus to be adjusted during camera module integration.

Q: Is the aperture adjustable?
A: No. The lens uses a fixed F2.5 aperture.

Q: What applications are suitable for this lens?
A: Typical applications include compact monitoring cameras, IoT imaging devices, embedded camera modules, smart home cameras, robotic auxiliary cameras, and other space-constrained imaging systems.
