Pinhole Lens – CCL13042M9PMP

CCL13042M9PMP Pinhole lens 4mm 1/3″ IR MP HD CCTV M9 mount lens for Covert hidden Surveillance

4.2mm M9 Pinhole Lens for Compact Embedded Cameras

This 4.2mm M9 pinhole lens is designed for compact camera systems that require a discreet optical form factor with a wide 80° diagonal field of view. With a 1/3″ image format, F2.8 fixed aperture, 0.2m minimum object distance, and only 10.5mm TTL, it provides a practical optical solution for space-constrained surveillance, monitoring, and embedded vision devices.

Product Core Highlights

• 4.2mm fixed focal length for stable wide-angle imaging
• 80° diagonal FOV provides broad scene coverage
• Compact M9 × 0.5 mount for space-constrained camera designs
• 10.5mm TTL supports compact embedded optical assemblies
• F2.8 fixed aperture provides a consistent optical configuration

M9 Pinhole Lens Applications & Compatible Devices

The compact mechanical dimensions and pinhole configuration make this lens suitable for embedded camera designs where the optical opening needs to remain small and discreet. The 4.2mm focal length and 80° diagonal FOV provide useful coverage for indoor observation, equipment monitoring, access areas, and other close-to-medium-range imaging tasks.

Typical compatible devices include compact security cameras, miniature monitoring cameras, embedded inspection cameras, access-control equipment, smart devices, and other camera modules where installation space is limited. The 0.2m M.O.D. also makes the lens suitable for applications that need to capture subjects relatively close to the camera.

Designed for compact embedded surveillance and monitoring applications.

For projects involving compact camera modules, you can also explore TOWIN’s Pinhole Lens solutions and M12 Lens products for alternative optical configurations.

When selecting a pinhole lens, the relationship between sensor size, focal length, and field of view should be considered carefully. TOWIN’s Sensor Guide provides additional information about sensor compatibility, while the Lens Selection Guide can help determine the appropriate focal length and lens configuration for a specific camera system.

Why Choose This 4.2mm Pinhole Lens?

This lens is particularly suitable when compactness and discreet imaging are more important than long-range optical performance. Compared with larger conventional camera lenses, its M9 mount and 10.5mm TTL allow optical integration into smaller camera housings. The fixed focal length and fixed aperture also provide a straightforward configuration for embedded camera manufacturers.

For customized requirements involving focal length, mount configuration, optical performance, or mechanical dimensions, TOWIN can provide OEM/ODM optical development according to project requirements. You can contact TOWIN for a customized lens evaluation.

Frequently Asked Questions

Q: What type of lens is this?
A: This is a 4.2mm fixed focal length pinhole lens designed for compact embedded camera and discreet monitoring applications.

Q: What is the field of view of this pinhole lens?
A: The lens provides an 80° diagonal field of view when used with the specified 1/3″ image format.

Q: What sensor size is compatible with this lens?
A: The lens is specified for a 1/3″ image format, making it suitable for camera modules using sensors within this format.

Q: What is the mount of this pinhole lens?
A: It uses an M9 × 0.5 mount, making it suitable for compact camera assemblies designed around an M9 mounting interface.

Q: Is this lens a fixed focal length lens?
A: Yes. The focal length is fixed at 4.2mm and the zoom configuration is fixed, providing a consistent field of view.

Q: What is the minimum object distance?
A: The specified M.O.D. is 0.2m, allowing the lens to capture objects at relatively close distances.

Q: Is the aperture adjustable?
A: No. The lens uses a fixed F2.8 aperture rather than a manually or automatically adjustable iris.

Q: Can TOWIN customize this pinhole lens?
A: TOWIN can evaluate customized optical and mechanical requirements such as focal length, mount, field of view, and lens dimensions for specific embedded camera projects.
