M12 Lenses – SP08012704228F

SP08012704228F is 2-Megapixel M12 CCTV lens with Built-In IR Filter, 1/2.7″ sensor size, M12 mount, 49° diagonal FOV, F2.8 aperture, for security surveillance.

8mm 2MP M12 Fixed Focal Miniature Lens

This 8mm M12 fixed focal lens is designed for compact 2MP imaging systems requiring a controlled 49° diagonal field of view, F2.8 aperture, and reliable image capture. With an M12×0.5 mount, 0.3m minimum object distance, manual focus, and a 5G+IRCF optical structure, it is suitable for embedded vision, industrial inspection, smart devices, and compact machine vision cameras.

The 8mm focal length provides a narrower field of view than short-focal-length M12 lenses, making this lens suitable when the imaging system needs to concentrate on a defined inspection area while maintaining a compact optical footprint. For more information about selecting focal length and matching the lens to an imaging system, see the Lens Selection Guide.

M12 Fixed Focal Lens Core Highlights

• 8mm fixed focal length provides a controlled field of view for defined inspection areas.
• 2MP optical resolution supports common industrial and embedded imaging applications.
• M12×0.5 mount enables compact integration with small-format cameras and vision modules.
• F2.8 fixed aperture provides a stable optical configuration for consistent imaging.
• 5G + IRCF structure combines a multi-element optical design with an infrared-cut filter configuration.

8mm M12 Fixed Focal Lens Applications

Core Application Scenes

The 8mm focal length and 49° diagonal FOV make this lens suitable for applications where the camera needs to cover a specific target area without using an ultra-wide perspective. Its 0.3m M.O.D. also supports relatively close-range imaging in compact inspection systems.

Typical applications include:

• Compact machine vision inspection
• Embedded vision systems
• Industrial camera modules
• Smart equipment imaging
• Barcode and code-reading systems
• Object presence and positioning detection
• Small-part inspection
• Robotics vision modules
• Intelligent monitoring equipment

Designed for compact machine vision and embedded imaging applications where a controlled field of view and small M12 optical interface are required.

Compatible Devices

This lens can be integrated into:

• 1/2.7″ industrial camera modules
• Compact machine vision cameras
• Embedded vision cameras
• Smart inspection devices
• Robotics vision modules
• Industrial monitoring equipment
• Small-format imaging systems

The M12×0.5 mount is particularly suitable for compact camera assemblies where installation space is limited. TOWIN also provides a range of M12 Lenses for systems requiring different focal lengths, fields of view, and optical configurations.

Optical Configuration and Selection Considerations

The 8mm focal length produces a 49° diagonal, 42° horizontal, and 24° vertical FOV on the specified 1/2.7″ image format. This makes it appropriate for applications where the target needs to occupy a defined portion of the image rather than requiring extremely broad scene coverage.

When selecting an M12 lens, the relationship between sensor size, focal length, working distance, and required field of view should be evaluated together. TOWIN’s Focal Length Calculator can be used to estimate the focal length required for a specific imaging setup.

The fixed F2.8 aperture and fixed iris simplify the optical configuration, while manual focus allows the lens to be adjusted during system setup. With a 0.3m minimum object distance, the lens can be considered for relatively close industrial imaging tasks where the target is positioned within a controlled working range.
