Pinhole Lens – CCL1322PMPR2

22mm M12 Pinhole Lens | 13° FOV F1.6 Lens

The 22mm M12 Pinhole Lens is a compact fixed-focus optical solution designed for imaging systems that require a narrow, controlled field of view. With a 22mm focal length and 13° horizontal FOV, this M12 pinhole lens is suitable for targeted observation where the camera needs to concentrate on a defined area rather than capture a wide scene. The F1.6 aperture provides useful light-gathering capability for compact imaging applications.

Designed for 1/3″ image formats, this 22mm M12 Pinhole Lens features an M12x0.5 mount, fixed iris, manual focus and a 30mm TTL. Its compact mechanical configuration makes it suitable for embedded camera modules and space-constrained devices. Its 0.2 m minimum object distance adds flexibility for installations that place the camera near targets.

M12 Pinhole Lens Core Highlights

• 22mm Long Focal Length: Provides a controlled 13° horizontal field of view for targeted imaging.
• F1.6 Aperture: Supports effective light collection in compact imaging systems.
• 1/3″ Image Format: Designed for camera modules using 1/3″ sensors.
• M12x0.5 Mount: Enables integration into compact embedded camera systems.
• 30mm TTL: Provides a relatively compact optical package for space-conscious product designs.

Narrow-FOV Optical Design for Targeted Imaging

The main advantage of this 22mm M12 Pinhole Lens is its 13° horizontal field of view. Compared with shorter focal length pinhole lenses, the longer focal length produces a tighter viewing area, allowing the camera to concentrate on a specific target.

This makes the lens suitable for applications where unnecessary background information should be minimized. Instead of covering a large scene, the optical system can be positioned to observe a specific entrance, equipment area, inspection point or other predefined target.

When selecting a narrow-FOV lens, focal length should be evaluated together with sensor size and target distance. TOWIN’s FOV Calculator can help engineers estimate the required focal length for a specific sensor and viewing area.

M12 Pinhole Lens Applications

Targeted Security Monitoring

The 13° FOV is suitable for compact security systems that need to monitor a specific area rather than provide broad scene coverage. This lens fits devices that observe entrances, corridors, restricted areas and other predefined targets.

Access Control Camera Modules

For access-control equipment, a narrow field of view can help concentrate the camera on a designated checkpoint or entrance zone. The compact M12 interface lets designers fit this lens into small camera modules with limited installation space.

Embedded Equipment Monitoring

The 22mm focal length can be useful for monitoring a defined section of machinery, equipment or infrastructure. Instead of capturing a large surrounding area, the camera can be positioned to focus on a specific operating point or component.

Compact Inspection Systems

The lens can support embedded inspection devices where the optical field is predetermined and a relatively narrow viewing angle is preferred. The manual focus configuration allows installers to adjust focus according to the actual working distance.

Specialized OEM Imaging Devices

The combination of a 22mm focal length, 13° FOV and M12x0.5 mounting interface makes this lens suitable for custom camera modules and specialized OEM imaging equipment. It can be considered when the system requires a compact fixed-focus lens with controlled scene coverage.

Lens Selection Considerations

A 22mm focal length provides substantially tighter coverage than short focal length M12 pinhole lenses. Therefore, this model is more appropriate for targeted imaging and narrow-area observation than wide-area surveillance.

For a successful lens selection, consider:

• Camera sensor format
• Required horizontal and vertical FOV
• Target distance
• Required image resolution
• Available illumination
• Mechanical installation space
• Mounting interface
• Required focusing method

TOWIN’s Lens Selection Guide provides additional guidance for matching lens parameters with camera requirements.
