3.7mm M12 Pinhole Lens

This 3.7mm M12 Pinhole Lens is a compact fixed focal lens designed for discreet embedded imaging systems using 1/3″ image sensors. With a 3.7mm focal length, 92° diagonal FOV, 70° horizontal FOV and 55° vertical FOV, the lens provides a wide viewing area while maintaining a compact optical structure. The F2.5 fixed aperture supports consistent imaging performance, while the M12×0.5 mount allows easy integration with miniature camera modules. With a 10.5mm TTL and 0.2m minimum object distance, this M12 pinhole lens is well suited to applications where camera size, installation flexibility and discreet optical integration are important.

As a compact pinhole camera lens, it can be integrated into embedded security equipment, access control terminals, smart kiosks, compact monitoring devices and other space-constrained imaging systems. For additional information about selecting focal length, sensor format and field of view, see TOWIN’s Lens Selection Guide and Lens Basics.

M12 Pinhole Lens Core Highlights

• 3.7mm Wide-Angle Focal Length — Provides a 92° diagonal field of view for broad scene coverage in compact installations.
• Compact M12×0.5 Mount — Designed for integration with miniature camera modules and embedded imaging equipment.
• Discreet Pinhole Configuration — Suitable for applications where the optical opening needs to remain small and visually unobtrusive.
• F2.5 Fixed Aperture — Provides a consistent optical configuration for embedded camera applications.
• 10.5mm TTL & 0.2m M.O.D. — Compact optical dimensions with a practical minimum object distance for nearby scenes.

M12 Pinhole Lens Applications

Discreet Security Monitoring

The compact pinhole configuration makes this lens suitable for discreet monitoring equipment where the camera module must occupy limited space. The 70° horizontal FOV helps capture a relatively broad scene without requiring a long physical lens assembly.

Typical equipment includes:

• Compact security cameras
• Embedded monitoring modules
• Indoor surveillance devices
• Concealed camera housings
• Miniature monitoring equipment

Access Control & Identification Terminals

The 3.7mm focal length and 0.2m M.O.D. make this lens appropriate for compact terminals positioned relatively close to users. It can be integrated into access control systems, visitor terminals and other embedded devices requiring a discreet camera module.

Suitable equipment includes:

• Access control terminals
• Visitor management terminals
• Door-entry camera modules
• Compact identification devices
• Embedded biometric terminals

When the application requires facial or biometric imaging, lens selection should also consider sensor size, distortion, working distance and illumination conditions. See TOWIN’s Biometric Recognition Solutions for additional guidance.

Smart Kiosks and Interactive Devices

The compact M12 form factor allows the lens to be integrated into space-constrained interactive equipment. Its 92° diagonal FOV can help capture users or objects positioned within a relatively broad area in front of the device.

Potential applications include:

• Smart kiosks
• Self-service terminals
• Interactive displays
• Information terminals
• Compact IoT devices

Embedded Vision Systems

This M12 pinhole lens is also suitable for embedded vision systems where a compact optical module is preferred over a larger C-mount or CS-mount assembly. The fixed focal configuration simplifies integration when the camera operates at a defined installation distance.

Typical devices include:

• Embedded vision cameras
• Compact inspection modules
• IoT imaging devices
• Smart electronic equipment
• Miniature camera modules

Compatible Devices

This 3.7mm M12 pinhole lens can be considered for use with:

• 1/3″ embedded camera modules
• M12 camera boards
• Compact security cameras
• Access control camera modules
• Smart kiosks and terminals
• IoT imaging devices
• Miniature monitoring cameras
• Space-constrained embedded vision systems

Before final selection, verify the camera sensor format, active image area, mechanical clearance and required working distance. TOWIN’s FOV Calculator can also be used to evaluate the relationship between focal length, sensor size and field of view.

Frequently Asked Questions

Q: What type of lens is this 3.7mm M12 lens?

A: This is a pinhole lens with a 3.7mm fixed focal length and M12×0.5 mount. It is designed for compact and discreet embedded imaging applications.

Q: What is the field of view of the 3.7mm M12 pinhole lens?

A: The lens provides a 92° diagonal FOV, 70° horizontal FOV and 55° vertical FOV when used with the specified 1/3″ image format.

Q: Is this lens a fixed focal lens?

A: Yes. The focal length is fixed at 3.7mm and the zoom configuration is fixed, making it suitable for camera systems with a predefined installation geometry.

Q: What camera sensors can this M12 pinhole lens be used with?

A: The specified image format is 1/3″. The final compatibility should be confirmed against the camera sensor’s active imaging area and mechanical interface.

Q: What is the minimum object distance of this lens?

A: The specified M.O.D. is 0.2m, meaning the lens is designed to focus on objects from approximately 0.2m under the specified optical configuration.

Q: Is the aperture adjustable?

A: No. The lens uses a fixed F2.5 aperture rather than a manually or automatically adjustable iris.

Q: What applications are suitable for a 3.7mm pinhole lens?

A: Typical applications include discreet security monitoring, access control terminals, smart kiosks, embedded camera modules, IoT devices and other compact imaging equipment.

Q: Can TOWIN customize this M12 pinhole lens?

A: TOWIN can evaluate optical and mechanical customization requirements based on the target sensor, FOV, working distance, housing dimensions and application environment. Contact TOWIN through the Lens Solution Request page for project-specific requirements.
