5.95mm M12 Low Distortion Lens Applications

Core Application Scenes

The 5.95mm focal length provides a 52.5° diagonal field of view when paired with a 1/3″ sensor. This moderate viewing angle is suitable for camera systems that need focused scene coverage rather than an ultra-wide perspective.

A major optical characteristic of this lens is its TV distortion below 0.9%. Controlled distortion can be useful in monitoring and imaging applications where straight lines and object proportions need to remain relatively consistent across the captured image.

The F2.8 fixed aperture provides a straightforward optical configuration for compact camera modules, while the 0.1m minimum object distance makes the lens suitable for relatively close-range imaging. This can be useful for indoor monitoring, equipment observation, access-area monitoring, and embedded visual devices.

The specified relative illumination above 76% is another useful characteristic for applications where image brightness across the frame matters. Combined with the 23.2mm TTL, the lens provides a practical optical package for compact camera designs.

Typical application scenarios include:

• Compact CCTV cameras
• Indoor security cameras
• Equipment monitoring
• Access-area monitoring
• Embedded monitoring cameras
• Industrial visual monitoring
• Close-range observation
• Smart security devices
• Compact IP camera modules
• Embedded vision systems

For applications involving security and monitoring, TOWIN’s Smart Security solution provides additional information about optical requirements. Engineers can also use the Lens Selection Guide when comparing focal length, sensor format, FOV, and distortion.

Compatible Devices

This lens can be considered for:

• 1/3″ 2MP cameras
• M12-mount CCTV cameras
• Compact IP camera modules
• Board cameras
• Embedded security cameras
• Industrial monitoring cameras
• Smart security imaging devices
• Compact embedded vision modules
• Close-range monitoring systems

The maximum 9.0mm image circle should be checked against the actual sensor dimensions during camera integration. Mechanical compatibility with the M12x0.5 thread should also be confirmed.

Designed for compact security and industrial monitoring applications requiring controlled distortion, close focusing, and consistent image illumination.

Frequently Asked Questions

Q1: What type of lens is this 5.95mm M12 lens?
A: It is a fixed focal M12 low distortion lens with 2MP resolution, F2.8 aperture, and a maximum image circle of 9.0mm.

Q2: What is the field of view of this lens?
A: At 1/3″, the specified FOV is 52.5° diagonal, 43° horizontal, and 33° vertical.

Q3: Is this a low distortion M12 lens?
A: Yes. The specified TV distortion is below 0.9%, making controlled geometric distortion one of the lens’s main optical characteristics.

Q4: What is the minimum object distance?
A: The specified MOD is 0.1m, or 100mm, making the lens suitable for relatively close-range imaging.

Q5: What does RI >76% mean?
A: RI refers to relative illumination, which describes the illumination level toward the image edges compared with the center. A value above 76% indicates the specified lens maintains a useful level of peripheral illumination.

Q6: Does the IRCF specification mean this is an IR corrected lens?
A: No. IRCF refers to an IR-cut filter-related optical configuration and should not automatically be interpreted as IR correction. This product should not be classified as an IR Corrected Lens based on IRCF alone.

Q7: Is this a fisheye or wide-angle lens?
A: No. The 52.5° diagonal FOV is a moderate field of view and does not support fisheye classification. The lens is better positioned as a low distortion fixed focal M12 lens.

Q8: What cameras can use this lens?
A: It can be considered for 1/3″ 2MP cameras, M12 board cameras, compact CCTV modules, embedded monitoring systems, and other cameras compatible with its image circle and M12x0.5 mount.
