16mm M12 Low Distortion Lens for 3MP Compact Imaging

This 16mm M12 low distortion lens is designed for compact imaging systems that require accurate target reproduction, stable optical performance, and precise image detail. With a 1/2.8″ optical format, 3MP resolution, 23° diagonal FOV, and distortion below 0.2%, it is well suited for close-range inspection, object recognition, measurement, and embedded vision applications. Designed for precision compact imaging applications, this fixed focal lens combines a compact M12 mount with a 21.1mm TTL for easy integration into space-constrained camera systems.

For projects that require correct focal length and sensor matching, engineers can also refer to the Sensor Guide and Lens Selection Guide.

Product Core Highlights

• 16mm fixed focal length: Provides a relatively narrow field of view for focused target imaging and close-range inspection.
• Ultra-low distortion <0.2%: Helps maintain accurate object geometry and minimizes image deformation at the edges.
• 3MP resolution: Suitable for detailed imaging with 3MP-class sensors in compact vision systems.
• F2.0 aperture: Provides a useful balance between optical brightness and compact lens design.
• M12 × 0.5 mount: Enables integration with compact camera modules and embedded vision equipment.

Low Distortion Lens Applications

The 16mm focal length and <0.2% distortion make this lens particularly suitable when the imaging system needs to isolate a target rather than capture a wide scene. Its 23° diagonal FOV provides more focused coverage than typical wide-angle M12 lenses, making it useful for applications where controlled framing and geometric accuracy are important.

Compact Machine Vision

The low distortion performance is beneficial for compact inspection systems that need consistent object geometry across the image. The 16mm focal length can help capture a defined inspection area while maintaining sufficient image detail with a 3MP sensor.

Designed for compact machine vision applications, this lens can be integrated into small inspection cameras, embedded vision modules, and space-constrained optical systems.

Object Recognition and Measurement

With distortion below 0.2%, the lens is suitable for applications where the apparent shape and position of an object need to remain accurate. It can support dimensional observation, component recognition, target positioning, and other image-analysis tasks.

Embedded Imaging Devices

The M12 × 0.5 mount and 21.1mm TTL make this lens suitable for compact camera designs where installation space is limited. It can be incorporated into embedded imaging equipment that requires a longer focal length without moving to a larger C-Mount optical system.

Inspection of Components and Parts

The relatively narrow FOV can help concentrate the camera’s imaging area on a specific component or inspection zone. This makes the lens useful for electronics inspection, small-part observation, assembly verification, and automated visual checking.

Compatible Devices

This lens can be considered for:

• Compact machine vision cameras
• Embedded vision camera modules
• Small inspection cameras
• Object recognition camera systems
• Component inspection devices
• Automated visual inspection equipment
• Compact measurement imaging systems
• OEM camera modules using M12 × 0.5 mounts
