Pinhole Lens – CCL1330PMPR

30mm M12 Pinhole Lens | 9° FOV F1.6 Lens

The 30mm M12 Pinhole Lens is a compact fixed-focus optical solution designed for imaging systems that require a narrow and controlled field of view. With a 30mm focal length and 9° horizontal FOV, this M12 pinhole lens is well suited to targeted observation where the camera needs to focus on a defined area rather than capture a wide scene. The F1.6 aperture provides useful light-gathering capability for compact imaging systems operating under varying illumination conditions.

Designed for 1/3″ image formats, this 30mm M12 Pinhole Lens features an M12x0.5 mount, fixed iris, manual focus and a 36.95mm TTL. The 0.2m minimum object distance provides flexibility for installations requiring relatively close positioning, while the narrow 9° FOV makes the lens suitable for applications where controlled scene coverage is more important than wide-area viewing.

M12 Pinhole Lens Core Highlights

• 30mm Long Focal Length: Provides a tight 9° horizontal FOV for focused target observation.
• F1.6 Aperture: Provides useful light-gathering capability for compact imaging applications.
• 1/3″ Image Format: Designed for camera modules using 1/3″ sensor formats.
• M12x0.5 Mount: Enables integration into compact embedded camera assemblies.
• 36.95mm TTL: Offers a practical optical configuration for specialized embedded imaging equipment.

Narrow 9° FOV for Targeted Imaging

The defining characteristic of this 30mm M12 Pinhole Lens is its 9° horizontal field of view. Compared with shorter focal length M12 pinhole lenses, the 30mm focal length produces a significantly tighter viewing area, allowing the camera to concentrate on a specific target.

This optical configuration is particularly useful when capturing unnecessary background information is undesirable. By limiting the viewing angle, system designers can position the camera toward a predefined observation zone such as a machine component, access point, equipment area or designated security target.

The appropriate focal length depends on the sensor size, target distance and required coverage. TOWIN’s FOV Calculator can help engineers estimate the relationship between sensor dimensions, focal length and field of view.

M12 Pinhole Lens Applications

Targeted Security Monitoring

The 9° FOV makes this lens suitable for security devices that need to observe a specific location rather than provide broad scene coverage. It can be considered for monitoring designated entrances, checkpoints, restricted areas and other predefined observation zones.

Access Control and Checkpoint Cameras

A narrow viewing angle can help concentrate the camera on a specific access point. The M12x0.5 mounting interface makes the lens suitable for compact access-control camera modules where installation space is limited and the observation area is clearly defined.

Equipment and Machine Monitoring

The 30mm focal length can be useful when a camera needs to monitor a specific part of equipment without capturing a large surrounding area. It can be integrated into embedded monitoring systems for machinery, control equipment and specialized devices.

Compact Inspection Devices

For inspection equipment with a predetermined observation area, the 9° FOV can help concentrate the camera on a specific inspection region. The manual focus configuration allows the installer to optimize focus according to the actual working distance.

Specialized Embedded Camera Modules

The compact M12 interface, fixed 30mm focal length and narrow FOV make this lens suitable for specialized OEM camera modules. It can be incorporated into custom imaging devices where the optical viewing area is defined during system design.

Lens Selection Considerations

The 30mm focal length provides a considerably narrower viewing angle than short focal length M12 lenses. This makes the model more appropriate for focused observation and targeted imaging than wide-area surveillance.

When selecting a 30mm M12 pinhole lens, consider:

• Camera sensor format
• Active sensor dimensions
• Required horizontal and vertical FOV
• Target distance
• Required image resolution
• Available illumination
• Lens installation space
• Mounting interface
• Required focus adjustment
