Ultra-Wide-Angle Lens Advantages

161° Ultra-Wide Field of View
The 161° diagonal FOV provides extensive scene coverage, making the lens suitable for applications where a conventional lens may leave significant areas outside the camera’s viewing range.

4MP Resolution
The 4MP optical configuration provides sufficient image detail for a wide range of surveillance, monitoring, and embedded vision applications while maintaining a compact optical design.

Compact M12x0.5 Mount
The standard M12x0.5 mount supports integration into compact board cameras, embedded vision modules, and space-constrained camera housings.

F2.0 Aperture
The F2.0 aperture provides a balanced light-gathering capability for indoor monitoring, security cameras, and other applications where maintaining adequate image brightness is important.

Ultra-Wide Optical Design
The 2.1mm focal length is optimized for extremely broad scene coverage, making it particularly useful for environmental awareness and wide-area monitoring.

Compact Optical Structure
The 15.12mm TTL and 3.72mm B.F.L. provide flexibility for compact camera integration, while the 3.37mm M.B.F.L. offers an additional mechanical reference for system design.

IR Cut Filter Configuration
The 2G5P+IRCF optical construction incorporates an IR cut filter, supporting visible-light imaging by reducing unwanted infrared transmission and helping maintain more natural daytime color reproduction.

Ultra-Wide-Angle Lens Applications

CCTV & Security Cameras
The 161° diagonal FOV makes this lens suitable for surveillance cameras that need to cover large indoor spaces, entrances, corridors, retail areas, or other locations where broad visual coverage is important.

Drone Imaging
The compact optical structure and 161° FOV can be useful for lightweight drone cameras requiring extensive environmental coverage and situational awareness.

See TOWIN’s Drone Imaging Solutions for additional drone camera lens options.

Embedded AI Cameras
The combination of 4MP resolution, ultra-wide viewing angle, and compact dimensions makes this lens suitable for embedded AI cameras where broad environmental information is more important than a narrow, highly magnified perspective.

Wide-Area Monitoring
The 161° diagonal field of view can help reduce blind spots in applications such as room monitoring, entrance observation, vehicle surroundings, and compact intelligent monitoring systems.

Lens Selection & Technical Considerations

Focal Length and Field of View
The 2.1mm focal length provides a 161° diagonal, 141° horizontal, and 82° vertical field of view. This makes the lens significantly wider than conventional M12 lenses and particularly suitable for applications requiring maximum scene coverage.

Use TOWIN’s FOV Calculator to evaluate the relationship between sensor size, focal length, and field of view for your camera configuration.

Distortion Consideration
The specified distortion is below -25%, which reflects the strong wide-angle optical characteristics of this 2.1mm lens. This design prioritizes broad scene coverage rather than geometrically precise image reproduction. For measurement or applications requiring highly accurate object dimensions, a low-distortion lens should be considered.

Sensor Compatibility
The lens is designed for a 1/2.9″ image format and supports 4MP resolution. The camera sensor should be matched with the lens image format to ensure the available sensor area is properly covered and to avoid vignetting.

For more information, visit the Sensor Guide.

Aperture and Lighting
The fixed F2.0 aperture provides a balanced optical solution for general surveillance and embedded imaging. Actual low-light performance depends on the camera sensor, exposure settings, illumination level, and image-processing system.

Optical Construction and IR Cut Filter
The 2G5P+IRCF construction includes an IR cut filter for visible-light imaging. This configuration is appropriate for standard color cameras where unwanted infrared wavelengths need to be controlled. It should be distinguished from an IR-corrected lens designed specifically for near-infrared imaging.

Mechanical Integration
The 15.12mm TTL, 3.72mm B.F.L., and 3.37mm M.B.F.L. provide useful mechanical references when integrating the lens into a compact camera housing. The final camera design should also account for sensor position, lens barrel clearance, focus adjustment, and housing dimensions.
