Pinhole Lens – CCL13035PMP

CCL13035PMP Pinhole lens 3.5mm 1/3″ IR MP HD CCTV M12 mount lens for Covert hidden Surveillance

3.5mm M12 Pinhole Lens

This 3.5mm M12 pinhole lens is designed for compact camera modules that require a discreet optical configuration and broad scene coverage. With a 1/3″ image format and a 100° diagonal field of view, 80° horizontal FOV, and 60° vertical FOV, the lens captures a wide area while maintaining a compact optical structure. Its F2.5 fixed aperture, manual focus, and 12mm TTL provide a practical configuration for embedded imaging systems where available installation space is limited.

The M12×0.5 mount makes this 3.5mm M12 pinhole lens suitable for integration with miniature camera modules and custom camera housings. The 0.3m minimum object distance also supports applications that require relatively close-range observation. Its combination of wide-angle coverage and compact dimensions makes it suitable for discreet monitoring, access control, embedded IoT cameras, compact inspection equipment, and other small-form-factor imaging devices.

M12 Pinhole Lens Core Highlights

• 100° Wide-Angle FOV – Provides broad scene coverage for compact monitoring and embedded vision systems.
• 3.5mm Fixed Focal Length – Suitable for applications requiring a relatively wide viewing angle from a compact optical assembly.
• Compact 12mm TTL – Helps simplify integration into small camera housings and space-limited devices.
• M12×0.5 Mount – Provides a widely used mechanical interface for miniature camera modules.
• F2.5 Fixed Aperture – Offers a consistent aperture configuration for embedded imaging applications.

Discreet Pinhole Optical Design

Pinhole lenses are commonly selected for camera systems where the optical opening needs to remain small and unobtrusive. This makes them particularly useful for embedded devices and compact monitoring equipment in which the lens must fit behind a small aperture or within a restricted mechanical structure.

With a 12mm TTL, this lens provides a compact optical solution without sacrificing its 100° diagonal viewing coverage. The M12×0.5 thread further simplifies integration with compatible miniature camera modules.

For engineers comparing different optical configurations, the Lens Selection Guide provides useful guidance on focal length, sensor format, FOV, and other lens selection factors.

100° Wide-Angle Coverage

The 3.5mm focal length provides a 100° diagonal FOV, 80° horizontal FOV, and 60° vertical FOV on the specified 1/3″ image format.

This wide-angle configuration allows the camera to capture more of the surrounding scene from a relatively short installation distance. It can be especially useful where camera placement is constrained and a broader viewing area is required.

The 3.5mm focal length also provides a useful balance between compact optical construction and wide-angle coverage. For projects requiring a different viewing range, engineers can compare alternative focal lengths using TOWIN’s FOV Calculator.

M12 Pinhole Lens Applications

Discreet Security Monitoring

The compact pinhole configuration is suitable for security devices where the camera needs to maintain a low-profile appearance. The 80° horizontal FOV provides broad coverage for indoor monitoring areas, while the compact optical structure can be integrated into small camera enclosures.

Access Control Systems

Access control terminals often have limited internal space for optical components. This M12 pinhole lens can be integrated into compact camera modules used for entry monitoring, visitor observation, and controlled-area surveillance.

Embedded IoT Cameras

For IoT products with strict mechanical size requirements, the combination of a 12mm TTL and M12×0.5 mount provides a practical integration option. The 100° diagonal FOV can help capture a broader area without requiring a larger lens assembly.

Compact Inspection Devices

The 0.3m M.O.D. makes this lens suitable for selected close-range imaging applications. It can be integrated into compact inspection devices where the camera needs to observe a relatively broad area at a short working distance.

Kiosk and Terminal Imaging

Self-service kiosks, information terminals, and other interactive devices may require small embedded cameras for user or environmental monitoring. The discreet pinhole configuration helps minimize the visual footprint of the camera module while providing wide-angle scene coverage.

Miniature Embedded Vision Systems

This lens can also be considered for customized embedded vision products where space, mounting interface, and viewing angle are important design constraints. Its fixed focal length and fixed aperture provide a straightforward optical configuration for predefined imaging requirements.

Designed for compact embedded imaging, discreet monitoring, and wide-angle camera applications.

Lens Selection Considerations

Selecting a pinhole lens requires more than matching the focal length. The sensor format, required field of view, working distance, optical length, mount, focusing method, and available installation space should all be considered.

This lens is specified for a 1/3″ image format with a 3.5mm focal length. If the camera uses another sensor format, the resulting FOV and image coverage may differ. Engineers should therefore verify the sensor and optical configuration together before finalizing the lens.

For more information about the relationship between image sensors and lens selection, refer to the Sensor Guide.
