Pinhole Lens – CCL1270PMP

70mm M12 Pinhole Lens | 5° FOV F1.6 2MP Lens

The 70mm M12 Pinhole Lens is a long focal length fixed-focus optical solution designed for compact imaging systems that require a very narrow field of view. With a 70mm focal length and 5° horizontal FOV, this 2MP pinhole lens provides targeted imaging of distant or specific objects while maintaining a compact M12x0.5 mounting interface. The F1.6 aperture helps provide strong light-gathering capability for applications where available illumination may vary.

With a 1/2″ image format, manual focus, fixed iris and 72.3mm TTL, this M12 pinhole lens is suitable for embedded camera designs where controlled viewing angles and compact mechanical integration are important. Compared with shorter focal length pinhole lenses, its narrow 5° FOV makes it particularly suitable for applications requiring focused observation rather than wide-area coverage.

For systems requiring a different viewing range, TOWIN also provides a range of M12 Lenses covering different focal lengths and optical configurations.

M12 Pinhole Lens Core Highlights

• 70mm Long Focal Length: Provides a narrow 5° horizontal field of view for targeted imaging.
• F1.6 Aperture: Offers useful light-gathering capability for compact imaging systems.
• 2MP Resolution: Suitable for 2MP camera sensors and monitoring applications requiring focused image capture.
• M12x0.5 Mount: Supports compact camera integration and space-constrained device designs.
• Fixed Focal & Manual Focus: Provides a straightforward optical configuration for applications with a defined imaging distance.

Designed for Targeted Long-Range Imaging

The defining feature of this 70mm M12 Pinhole Lens is its 5° horizontal field of view. A narrow FOV reduces the amount of surrounding scene captured by the camera, allowing the optical system to concentrate on a specific area or target.

This makes the lens particularly useful when a camera needs to observe a defined target from a relatively distant position. The 70mm focal length also differentiates this model from shorter M12 pinhole lenses, making it a strong option for applications where a tighter viewing angle is preferred.

For optical selection, the required focal length and sensor size should always be considered together with the desired field of view. TOWIN’s FOV Calculator can help engineers estimate the relationship between sensor size, focal length and viewing area.

M12 Pinhole Lens Applications

Targeted Security Monitoring

The narrow 5° FOV can be useful in compact security camera systems where the camera is intended to observe a specific entrance, passage, machine area or other defined target instead of an entire scene. The 70mm focal length helps concentrate the optical field on a limited viewing area.

Embedded Inspection Cameras

The M12x0.5 interface and compact optical configuration make this lens suitable for embedded camera equipment where installation space is limited but a narrow viewing angle is required. It can be integrated into compact imaging modules, inspection devices and specialized monitoring equipment.

Access Control and Entrance Observation

For access-control equipment or compact surveillance devices that need to monitor a specific doorway, gate, corridor or checkpoint, the 5° FOV can help limit unnecessary background information and concentrate imaging on the intended observation zone.

Industrial Equipment Monitoring

The lens can be used for monitoring a defined component, indicator, operating area or machine section. Its long focal length is particularly useful when the camera cannot be positioned close to the target and a narrow viewing angle is preferred.

Specialized Embedded Vision Systems

The combination of a 70mm focal length, 2MP resolution and M12 mount makes the lens suitable for specialized embedded vision systems requiring a fixed, narrow optical perspective. Engineers can integrate it into custom camera modules where the optical field is predetermined during system design.

Optical Selection Considerations

A 70mm focal length produces a substantially narrower viewing angle than shorter M12 pinhole lenses. Therefore, this model is best selected when the application has a clearly defined target area.

For example, TOWIN’s shorter focal length pinhole models can provide progressively wider coverage, while this 70mm model is positioned toward the narrow-FOV end of the M12 pinhole lens range.

When selecting a pinhole camera lens, engineers should evaluate:

• Sensor format and active image area
• Required horizontal and vertical FOV
• Target distance
• Available installation space
• Required resolution
• Aperture and illumination conditions
• Mounting interface
• Required focusing method
