Low Distortion Lens – S06011806122F

S06011806122F is Low distortion 2-Megapixel lens with Built-In IR Filter, fixed aperture F2.2, M12/S-Mount CCTV lens, Suitable for security Surveillance.

6mm M12 Low Distortion Lens

The 6.0mm 2MP M12 low distortion lens is designed for 1/3″ image sensors and compact imaging systems that require controlled image geometry and a moderate field of view. With less than -0.6% distortion, a 43° horizontal FOV, and an F2.2 aperture, it provides a practical balance between image coverage, optical clarity, and compact system integration.

Featuring an M12 × 0.5 mount, 0.2m minimum object distance, and 23.2mm total track length, this fixed focal lens is well suited to embedded cameras, inspection equipment, smart monitoring devices, and compact machine vision applications.

M12 Low Distortion Lens Highlights

• 6.0mm fixed focal length provides stable and repeatable image framing
• 2MP resolution for compact vision and monitoring camera systems
• Low distortion below -0.6% helps maintain accurate image geometry
• 43° horizontal FOV at 1/3″ provides moderate scene coverage for controlled imaging
• M12 × 0.5 mount with 23.2mm TTL supports compact camera integration
• Relative illumination above 58% helps maintain practical brightness across the image

6mm M12 Low Distortion Lens Applications

Core Application Scenes

The 6.0mm M12 lens is designed for applications that require a controlled, moderate field of view rather than an ultra-wide viewing angle. At 1/3″, its 43° horizontal and 33° vertical FOV provide a balanced image area for cameras positioned at a defined working distance.

Its < -0.6% distortion specification makes the lens particularly suitable for imaging tasks where straight lines and object proportions need to remain relatively consistent. This can be useful in basic inspection, object detection, measurement-assisted vision, and fixed-position monitoring systems.

The 0.2m minimum object distance also supports relatively close-range imaging. Combined with the compact M12 interface and 23.2mm total track length, the lens can be integrated into camera modules where installation space is limited but a standard moderate-FOV lens is required.

With F2.2 aperture and >58% relative illumination, the optical design provides a practical combination of light transmission and image brightness for indoor and controlled-light environments.

Designed for compact inspection and embedded machine vision applications where moderate FOV, low distortion, and stable fixed-focus imaging are required.

Frequently Asked Questions

Q: What sensor format is this 6.0mm M12 lens designed for?
A: The specified FOV is based on a 1/3″ image sensor. The lens has a maximum image format of 9.0mm.

Q: What is the field of view of this 6.0mm lens?
A: At 1/3″, the lens provides a 52.5° diagonal FOV, 43° horizontal FOV, and 33° vertical FOV.

Q: Is this considered a low distortion lens?
A: Yes. The specified distortion is below -0.6%, making it suitable for applications where controlled geometric distortion is important.

Q: Is the 6.0mm M12 lens suitable for machine vision?
A: Yes. Its fixed focal length, 2MP resolution, low distortion, moderate FOV, and compact M12 mount make it suitable for selected machine vision and embedded inspection applications.

Q: What is the minimum object distance?
A: The minimum object distance is 0.2m, allowing the lens to support relatively close-range imaging.

Q: What does the >58% relative illumination specification mean?
A: Relative illumination indicates how well image brightness is maintained toward the edges of the image compared with the center. A value above 58% provides practical edge illumination for many compact imaging applications.

Q: What mount does this lens use?
A: It uses an M12 × 0.5 mount with a fixed iris, making it suitable for compact camera modules and embedded vision equipment.

Q: Does the IRCF specification mean the lens is IR corrected?
A: No. IRCF generally refers to an infrared-cut filter. The presence of an IRCF should not by itself be interpreted as optical IR correction.
