This 3MP 3.7mm M12 pinhole lens is designed for compact camera modules and embedded imaging systems where a discreet optical profile and wide scene coverage are required. Built for a 1/3″ image format, the lens provides a 92° diagonal FOV, 70° horizontal FOV, and 55° vertical FOV, allowing the camera to capture a broad viewing area from a compact installation position. Its F2.5 fixed aperture and manual focus configuration provide a straightforward optical solution for embedded camera integration.
With an M12×0.5 mount and 13mm total optical length, this 3.7mm M12 pinhole lens is suitable for compact camera housings where installation space is restricted. The 0.3m minimum object distance also makes it practical for selected close-range imaging applications. The 3MP resolution specification provides a suitable option for embedded monitoring, access control, IoT cameras, compact inspection devices, and other applications requiring a small wide-angle lens assembly.
The main advantage of a pinhole lens is its ability to provide imaging functionality within a discreet and space-efficient optical configuration. This makes pinhole optics particularly useful for products where a conventional, larger lens assembly would be difficult to accommodate.
This model combines a 3.7mm focal length with a 13mm TTL, providing a relatively compact optical package while maintaining a 92° diagonal field of view. The M12×0.5 interface also makes it easier to integrate the lens into compatible miniature camera modules.
For engineers evaluating different lens configurations, the Lens Selection Guide can help compare focal length, sensor format, FOV, and other key optical parameters.
The 3.7mm focal length produces a 92° diagonal FOV, 70° horizontal FOV, and 55° vertical FOV when used with the specified 1/3″ image format.
This viewing angle provides broader scene coverage than a standard narrow-angle lens, making the product suitable for cameras installed in relatively confined locations. A wide-angle configuration can help capture more of the surrounding environment without requiring the camera to be positioned far from the target area.
When determining whether this field of view is appropriate for a specific camera installation, TOWIN’s FOV Calculator can be used to evaluate focal length and sensor combinations.
Embedded Security Cameras
This M12 pinhole lens is suitable for compact security camera modules where a discreet optical appearance and broad viewing coverage are important. The 92° diagonal FOV can help capture a wider indoor scene while the pinhole configuration allows the optical assembly to remain visually unobtrusive.
Access Control and Entry Monitoring
Access control devices often combine a camera with a compact electronic and mechanical structure. The 3.7mm focal length provides useful wide-angle coverage for monitoring users approaching a terminal or entry point, while the M12 interface supports integration into compact camera assemblies.
IoT and Smart Device Cameras
Small connected devices may have limited internal space for optical components. The 13mm TTL and M12×0.5 mount provide a practical option for embedded camera designs, while the 3MP specification is suitable for applications that require more than basic VGA-level imaging.
Compact Inspection Equipment
For selected inspection systems with a working distance of around 0.3m or greater, the wide-angle configuration can provide useful coverage of the inspection area. The manual focus design allows the optical position to be adjusted during system integration.
Kiosk and Terminal Monitoring
Kiosks, self-service terminals, and interactive equipment may require compact cameras for user or environmental observation. The pinhole configuration can help maintain a low-profile appearance while the 70° horizontal FOV provides broad frontal coverage.
Miniature Embedded Vision Devices
The combination of 3MP imaging, 3.7mm focal length, M12×0.5 mounting, and compact mechanical dimensions makes this lens suitable for customized embedded vision equipment where both optical coverage and installation space are important considerations.
Designed for compact embedded cameras, discreet monitoring, access control, and wide-angle imaging applications.
This 3MP M12 pinhole lens can be considered for use with:
Before integration, the camera manufacturer or system designer should verify sensor compatibility, image circle, mechanical clearance, required FOV, working distance, and final image quality.
For a compact pinhole camera, the correct lens should be selected by considering the sensor format, focal length, field of view, working distance, TTL, mounting thread, and focus method together.
This model is optimized around a 1/3″ image format and 3.7mm focal length. Its 92° diagonal FOV is determined by the optical design and sensor combination, so using the lens with a different sensor format may change the effective field of view and image coverage.
The Sensor Guide provides additional information about matching camera sensors with appropriate optical systems.
