Pinhole Lens – CCL13025PMPR

2.5mm M12 Pinhole Lens

This 2.5mm M12 pinhole lens is designed for compact camera modules that require a wide field of view in a discreet optical configuration. With a 2.5mm fixed focal length, 125° diagonal FOV, 88° horizontal FOV, and 63° vertical FOV, the lens provides broad scene coverage while maintaining a compact M12×0.5 interface. Its 1/3″ image format, F2.5 aperture, 11.5mm TTL, and 0.2m minimum object distance make it suitable for space-constrained embedded imaging systems.

Designed for compact security cameras, access monitoring, embedded vision, and wide-area observation applications, this M12 pinhole lens is particularly useful where the camera needs to capture a large surrounding area from a compact installation position. The fixed 2.5mm focal length provides substantially wider coverage than conventional longer focal length pinhole lenses, while manual focus allows optical adjustment during camera integration.

M12 Pinhole Lens Core Highlights

• 2.5mm ultra-short focal length provides broad scene coverage for compact camera systems.
• 125° diagonal FOV captures a wide surrounding area from a relatively compact installation position.
• 88° horizontal and 63° vertical FOV provide practical wide-angle coverage for embedded monitoring applications.
• M12×0.5 mount and 11.5mm TTL support integration into small camera housings.
• 0.2m M.O.D. allows the lens to be used for relatively close-range wide-area observation.

M12 Pinhole Lens Applications

Wide-Area Security Monitoring

The 125° diagonal field of view makes this 2.5mm pinhole lens suitable for applications where the camera needs to monitor a broad scene from a fixed position. It can be used in compact security camera modules for entrances, corridors, retail spaces, equipment areas, and other locations where wider coverage is more important than long-distance magnification.

Access Control & Entrance Cameras

A wide-angle pinhole lens can help an access control camera capture both the immediate interaction area and surrounding space. The 2.5mm focal length is useful when the camera is installed close to an entrance, gate, terminal, or other access point and needs to maintain broad scene coverage.

The 0.2m M.O.D. also supports applications where subjects may be positioned relatively close to the camera.

Embedded Wide-Angle Cameras

The compact 11.5mm TTL and M12×0.5 mount make this lens suitable for embedded camera designs where both optical coverage and mechanical size are important. It can be integrated into compact monitoring modules, intelligent devices, and OEM camera assemblies.

TOWIN provides additional M12 Lens solutions for embedded vision and compact camera applications.

Indoor Monitoring

The wide FOV can be advantageous for indoor monitoring where a single compact camera needs to cover a relatively large area. Potential applications include room monitoring, small commercial spaces, counters, equipment zones, and localized security areas.

The 2.5mm focal length is particularly useful when the camera-to-scene distance is short and broad coverage is required.

Compact Equipment Observation

The lens can also be considered for equipment monitoring where the camera has limited installation space but needs to observe a larger area around the monitored equipment. Its short TTL helps support compact mechanical designs, while the fixed focal configuration simplifies the optical architecture.

Why Choose a 2.5mm Pinhole Lens?

A 2.5mm focal length provides a significantly wider field of view than longer focal length pinhole lenses. This makes the lens suitable when the camera must capture a large surrounding area from a short installation distance.

The 125° diagonal FOV is the key optical characteristic of this model. Instead of concentrating on a distant target like a 15mm pinhole lens, this configuration is better suited to broad scene coverage, close-range observation, and compact wide-angle camera designs.

For engineers comparing focal lengths and viewing coverage, TOWIN’s Lens Selection Guide provides additional guidance on matching optical parameters to application requirements.

Field of View and Working Distance

The lens provides a 125° diagonal, 88° horizontal, and 63° vertical field of view, making it suitable for wide-area imaging.

The actual scene coverage depends on the sensor dimensions and camera-to-object distance. A shorter focal length generally produces a wider field of view, while increasing the working distance increases the physical area captured by the camera.

Before finalizing the optical configuration, calculate the expected image coverage according to the target working distance and sensor dimensions.
