Low Distortion Lens – S06012705621F67

S06012705621F67 is Low distortion lens 2-Megapixel M12 mount CCTV with Built-In IR Filter, 6.0mm focal length, 65° diagonal field of view, and IP67 waterproof rating.

6.0mm M12 Low Distortion Lens

This 6.0mm M12 low distortion lens is designed for compact 2MP imaging systems using the 1/2.7-inch AR0237 sensor. With TV distortion below -2.9%, a 65° diagonal FOV, F2.1 aperture, and IP67 waterproof protection, it provides stable and geometrically accurate imaging for automotive, industrial, and outdoor vision applications.

M12 Low Distortion Lens Core Highlights

• Low distortion imaging: TV distortion below -2.9% helps maintain accurate object geometry and image proportions.
• 6.0mm fixed focal length: Provides a balanced 65° diagonal field of view for controlled scene coverage.
• 2MP AR0237 compatibility: Designed around the 1/2.7-inch AR0237 image sensor.
• Compact M12x0.5 mount: Suitable for space-constrained camera modules and embedded vision equipment.
• IP67 protection: Supports outdoor and automotive environments where protection against dust and water is required.

6.0mm M12 Low Distortion Lens Applications

Core Application Scenes

The 6.0mm focal length provides a more controlled field of view than ultra-wide M12 lenses, while the low-distortion optical design helps preserve the shape and relative position of objects in the image.

This makes the lens suitable for:

• Automotive surround and auxiliary vision: The IP67 structure supports camera systems exposed to dust, moisture, and outdoor operating conditions.
• Vehicle-mounted monitoring: The 56° horizontal FOV provides practical scene coverage without the excessive geometric deformation associated with fisheye optics.
• Industrial inspection: Low distortion helps maintain more accurate object dimensions and positions when images are used for visual inspection.
• Compact machine vision systems: The M12x0.5 interface and 20.51mm T.T.L. are suitable for compact embedded camera designs.
• Outdoor monitoring: IP67 protection makes the lens suitable for vision equipment operating in demanding outdoor environments.
• Object recognition: The controlled FOV and low optical distortion help maintain consistent image geometry for recognition algorithms.

Designed for automotive, compact machine vision, industrial inspection, and outdoor imaging applications.

Optical Design and Imaging Performance

The optical configuration combines a 6G lens structure with an IRCF (IR Cut Filter). The IRCF helps control unwanted infrared wavelengths in visible-light imaging and should not be confused with an IR-corrected optical design.

The < -2.9% TV distortion is a key characteristic of this model. Compared with highly distorted wide-angle or fisheye lenses, the optical design is intended to maintain a more natural relationship between real-world geometry and the captured image. This is useful for applications involving object measurement, positioning, recognition, or image-based analysis.

The F2.1 fixed aperture provides a practical balance between light transmission, optical compactness, and consistent imaging performance. Combined with the 6.0mm focal length and 0.3m M.O.D., the lens can be used for relatively controlled viewing distances rather than extremely close-range macro imaging.

Frequently Asked Questions

Q1: What sensor size is this 6.0mm M12 lens designed for?
A: This lens is designed for a 1/2.7-inch image format and is specified with the 2MP AR0237 sensor.

Q2: What is the field of view of this M12 lens?
A: With the AR0237 sensor, the lens provides approximately 65° diagonal, 56° horizontal, and 31° vertical FOV.

Q3: Is this a low distortion lens?
A: Yes. The specified TV distortion is below -2.9%, making it suitable for applications where image geometry needs to remain relatively accurate.

Q4: Is the 6.0mm lens a fisheye lens?
A: No. Its 65° diagonal FOV and low distortion are characteristic of a conventional low-distortion fixed focal lens rather than a fisheye design.

Q5: What does IRCF mean in the optical structure?
A: IRCF refers to an IR Cut Filter, which blocks unwanted infrared wavelengths in visible-light imaging. It does not mean that the lens itself is optically IR corrected.

Q6: Is this lens suitable for outdoor or automotive applications?
A: Yes. The IP67 waterproof rating makes it suitable for protected outdoor and automotive vision applications where resistance to dust and water is required.

Q7: What is the minimum object distance?
A: The specified M.O.D. is 0.3m, meaning the lens is designed to focus from approximately 0.3 meters under the specified configuration.

Q8: What type of camera mount does this lens use?
A: It uses an M12x0.5 mount, making it compatible with camera modules and compact vision systems designed for M12 lenses.
