Pinhole Lens – CCL13037PMP

CCL13037PMP Pinhole lens 3.7mm 13 IR MP HD CCTV M12 mount lens for Covert hidden Surveillance

3.7mm M12 Pinhole Lens

This 3.7mm M12 pinhole lens is designed for compact camera modules and embedded imaging systems that require a discreet optical design with a wide viewing range. Featuring a 1/3″ image format, 92° diagonal FOV, 70° horizontal FOV, and 55° vertical FOV, this M12 pinhole lens provides broad scene coverage while maintaining a compact 11mm total optical length. The F2.5 fixed aperture and manual focus design offer a practical solution for space-constrained imaging equipment. With a 0.3m minimum object distance and M12×0.5 mount, it is suitable for applications where the lens needs to be integrated into a small camera housing or concealed behind a limited optical opening.

For engineers selecting a compact optical module, this M12 pinhole lens combines a short 3.7mm focal length, wide-angle coverage, manual focusing, and a compact mechanical structure. It can be integrated into embedded security cameras, access monitoring devices, compact inspection equipment, and other small-form-factor imaging systems.

M12 Pinhole Lens Core Highlights

• Compact 11mm TTL – Suitable for small camera housings and space-constrained optical assemblies.
• 3.7mm Wide-Angle Focal Length – Provides 92° diagonal FOV for broader scene coverage.
• M12×0.5 Mount – Compatible with a wide range of compact embedded camera modules.
• F2.5 Fixed Aperture – Provides a consistent optical aperture for stable imaging configurations.
• Manual Focus Design – Allows optical focus adjustment during camera module integration and setup.

Compact Pinhole Design for Discreet Imaging

A pinhole lens is often selected when the camera needs to maintain a small and unobtrusive optical footprint. Compared with larger conventional camera lenses, this type of optical design can be integrated into compact housings where available installation space is limited.

The 11mm TTL of this lens makes it particularly suitable for miniature camera assemblies, while the M12×0.5 thread provides a commonly used mechanical interface for compact imaging modules. The 3.7mm focal length further expands the visible area without requiring a physically large lens assembly.

For more information about choosing the appropriate lens architecture and optical specifications, see the Lens Selection Guide.

Wide-Angle Imaging Performance

With a 92° diagonal FOV, 70° horizontal FOV, and 55° vertical FOV, this lens provides significantly broader scene coverage than a conventional narrow-angle lens.

The wide-angle configuration is useful when the camera needs to observe a relatively large area from a short installation distance. It can help reduce the number of cameras required in certain compact monitoring or embedded imaging designs.

When determining whether the 3.7mm focal length provides sufficient coverage for a particular sensor and working distance, engineers can use the FOV Calculator to evaluate the relationship between sensor size, focal length, working distance, and field of view.

M12 Pinhole Lens Applications

Embedded Security Cameras

The compact pinhole construction makes this lens suitable for embedded security cameras where the optical assembly needs to occupy minimal space. The 70° horizontal FOV provides a relatively broad viewing area for indoor monitoring applications, while the 11mm TTL helps simplify integration into compact camera housings.

Access Control and Entry Monitoring

Compact imaging devices used for access monitoring often require lenses that can fit into restricted mechanical spaces. This M12 pinhole lens can be integrated into small camera modules used around entrances, controlled areas, kiosks, and other access points where a discreet optical configuration is preferred.

Compact Inspection Devices

The 3.7mm focal length and 0.3m M.O.D. make the lens suitable for selected close-range imaging configurations. It can be considered for compact inspection devices that need to capture a relatively broad area without using a larger optical assembly.

Embedded IoT Imaging

Small IoT cameras and embedded vision products frequently have strict limitations on lens size and mechanical depth. The combination of an M12×0.5 mount, 11mm TTL, and wide-angle FOV makes this lens suitable for compact imaging modules integrated into connected devices.

Miniature Monitoring Equipment

For monitoring equipment installed in confined spaces, a compact pinhole lens can provide optical functionality while helping reduce the size of the camera enclosure. The fixed aperture and fixed focal length also simplify the optical configuration for applications with a predefined imaging distance.

Designed for compact embedded imaging and discreet monitoring applications.

How to Select a Pinhole Lens for Your Camera

When selecting a pinhole lens, focal length alone should not determine the final configuration. The image sensor format, required field of view, working distance, lens mounting interface, optical length, and focusing requirements should all be considered.

For this lens, the 1/3″ image format and 3.7mm focal length provide a 92° diagonal FOV. If your camera uses a different sensor format or requires a different viewing angle, TOWIN can help evaluate the appropriate focal length and optical configuration.

You can also review the Sensor Guide to understand how sensor dimensions affect lens selection.
