Pinhole Lens – CCL1315PMP

CCL1315PMP Pinhole lens 10mm 1/3″ 18° HD CCTV M12 mount lens for Covert Surveillance, hidden camera

15mm M12 Pinhole Lens

This 15mm M12 pinhole lens is designed for compact camera modules that require a narrow, controlled field of view and discreet optical integration. With a 15mm fixed focal length, 18° horizontal FOV, F1.6 aperture, and 1/3″ image format, this lens provides targeted image coverage for applications where the camera needs to focus on a specific area rather than capture a wide scene. The M12×0.5 mount and 22.32mm TTL support integration into compact embedded camera systems.

Designed for discreet monitoring, access control, equipment observation, and embedded security applications, this fixed focal pinhole lens combines a relatively long focal length with a compact M12 mounting configuration. Its F1.6 aperture provides a useful optical advantage for applications requiring more light collection than slower compact lenses, while the 0.2m minimum object distance supports close-range imaging.

M12 Pinhole Lens Applications

Discreet Security Monitoring

The 15mm focal length and 18° horizontal FOV make this lens suitable for monitoring a defined area where a broad panoramic view is unnecessary. It can be integrated into compact security cameras designed to observe entrances, counters, restricted areas, equipment zones, or other specific locations.

The pinhole configuration can also help maintain a discreet camera appearance where the optical opening needs to occupy limited space.

Access Control Systems

Access control devices often require a camera to observe a relatively specific area around an entry point or interaction zone. The controlled field of view of this 15mm M12 pinhole lens can help concentrate image coverage on the required area without unnecessarily capturing the surrounding environment.

The 0.2m M.O.D. also makes the lens suitable for applications where the camera is installed relatively close to the subject.

Equipment & Machine Monitoring

For equipment monitoring, the camera may need to observe a specific component, display, indicator, or operating area. A 15mm fixed focal lens can provide more concentrated coverage than short focal length lenses, making it useful for targeted observation.

The lens can be integrated into compact monitoring modules where limited installation space requires an M12 optical interface.

Embedded Vision Devices

The combination of an M12×0.5 mount, fixed 15mm focal length, and 22.32mm TTL makes this lens suitable for OEM camera modules and embedded vision equipment. It can be considered for compact imaging devices where mechanical integration and controlled image coverage are important design factors.

Close-Range Observation

With a specified minimum object distance of 0.2m, the lens can be considered for relatively close-range observation where the camera needs to concentrate on a particular object or area. Potential applications include equipment interfaces, access points, compact inspection zones, and localized monitoring.

Why Choose a 15mm Pinhole Lens?

A longer focal length is useful when the imaging system needs to concentrate on a defined area. Compared with short focal length lenses, a 15mm lens provides a narrower field of view, which can reduce unnecessary surrounding scene coverage and help the camera focus on a specific target.

When selecting this type of lens, the most important factors include sensor format, horizontal FOV, working distance, aperture, and mechanical dimensions. TOWIN’s Sensor Guide provides additional information about matching lenses with image sensors.

Field of View and Working Distance

The 18° horizontal FOV gives this lens a relatively concentrated viewing angle. This makes it more appropriate for targeted imaging than applications requiring broad scene coverage.

The actual object coverage depends on both the camera-to-object distance and the sensor configuration. Before selecting the final lens, it is recommended to calculate the required image coverage based on the intended working distance.

Use the FOV Calculator to estimate the expected field of view and image coverage for your camera configuration.

Frequently Asked Questions

Q: What type of lens is this product?
A: This product is a 15mm fixed focal M12 pinhole lens designed for compact and discreet camera systems requiring a controlled field of view.

Q: What is the field of view of this 15mm M12 pinhole lens?
A: The specified horizontal field of view is 18°. The actual image coverage also depends on the sensor format and working distance.

Q: Is this lens suitable for a 1/3″ sensor?
A: Yes. The lens is specified for a 1/3″ image format and can be used with compatible 1/3″ image sensors.

Q: What aperture does the lens use?
A: The lens has a fixed F1.6 aperture, providing a relatively bright optical configuration for compact imaging applications.

Q: Does this lens have manual focus?
A: Yes. The lens uses manual focus and has a specified minimum object distance of 0.2m.

Q: What mount does this pinhole lens use?
A: The lens uses an M12×0.5 mount, which is commonly used for compact embedded camera modules.

Q: Is a 15mm pinhole lens suitable for wide-angle applications?
