Low Distortion Lens – S35011801124

S35011801124-Low distortion manual focus fixed-zoom 1/1.8″ M12 mount 8MP F2.4 lens with 35mm focal length and 14.5° diagonal F.O.V. for general surveillance.

35mm 8MP M12 Ultra Low Distortion Machine Vision Lens

This 35mm 8MP M12 low distortion lens is designed for compact machine vision and industrial imaging systems that require a narrow, controlled field of view and highly accurate image reproduction. With a 1/1.8″ image format, <0.7% distortion, 8MP resolution, and F2.4 aperture, it is well suited to detailed inspection of objects located at relatively long working distances.

The M12x0.5 mount provides compact integration for embedded cameras and space-constrained vision equipment, while the 1m minimum object distance makes this lens particularly suitable for applications where the camera must remain away from the inspection target.

Product Core Highlights

• 35mm telephoto focal length: Provides a narrow 14.5° diagonal FOV for focused imaging of distant or localized targets.
• Ultra-low distortion: <0.7% distortion helps preserve object geometry for inspection and measurement-oriented vision applications.
• 8MP resolution: Supports detailed image capture with 1/1.8″ high-resolution sensors.
• F2.4 fixed aperture: Provides a practical balance between optical performance and compact lens construction.
• Compact M12x0.5 mount: Enables integration into embedded machine vision cameras and space-limited industrial equipment.

M12 Low Distortion Lens Applications

Unlike short-focal-length M12 lenses designed for broad scene coverage, this 35mm lens provides a narrow field of view that allows the camera to focus on a specific area from a greater distance. Its <0.7% distortion is a key advantage when image geometry and dimensional consistency are important.

Designed for long-distance machine vision inspection applications, the lens can be used when the camera cannot be positioned directly beside the inspection target. The 35mm focal length allows a defined area to be captured while maintaining physical separation between the camera and the object.

It is particularly suitable for dimensional inspection and part measurement, where excessive lens distortion can affect the apparent shape or position of components. The ultra-low distortion characteristic helps maintain more consistent geometry across the image, while 8MP resolution supports detailed inspection of edges, features, and component surfaces.

The lens can also be used for production-line monitoring of specific zones, including inspection of components moving along a conveyor, monitoring of assembly stations, and observation of machinery from a fixed position. Its 14.5° diagonal FOV is useful when a broad scene is unnecessary and the imaging system needs to isolate a specific target area.

With a 1m M.O.D., the lens is better suited to medium- and longer-distance setups than close-range compact inspection. Manual focus allows engineers to optimize image sharpness during system installation according to the actual working distance.

Typical compatible devices and systems include:

• 8MP machine vision cameras
• Compact industrial cameras
• Embedded vision cameras
• Dimensional inspection systems
• Long-distance inspection cameras
• Conveyor inspection systems
• Component measurement equipment
• Automated optical inspection equipment
• Robotic inspection cameras
• Fixed-position industrial monitoring cameras

For advanced automated inspection projects, TOWIN’s Machine Vision solutions can be used alongside this lens to develop optical configurations matched to specific sensor and working-distance requirements.

Frequently Asked Questions

Q: What type of lens is this 35mm M12 lens?
A: It is an 8MP M12 fixed focal machine vision lens with a 35mm focal length and <0.7% distortion, designed for narrow-field industrial imaging applications.

Q: Is this a low distortion lens?
A: Yes. With distortion specified below 0.7%, it provides very low geometric distortion and is suitable for applications where accurate image shape and positioning are important.

Q: What is the field of view of the 35mm lens?
A: On a 1/1.8″ sensor, the lens provides a 14.5° diagonal, 11.7° horizontal, and 8.8° vertical field of view.

Q: Why use a 35mm focal length for machine vision?
A: A 35mm focal length provides a relatively narrow field of view, making it useful when the camera needs to isolate a specific target area or remain farther away from the object.

Q: What is the minimum object distance?
A: The specified M.O.D. is 1m, making the lens particularly suitable for medium- to longer-distance imaging setups rather than very close-range inspection.

Q: Is the focus adjustable?
A: Yes. The lens uses manual focus, allowing engineers to adjust focus during installation according to the required working distance.

Q: Is this lens suitable for dimensional inspection?
A: Yes. Its <0.7% distortion and 8MP resolution make it a strong option for applications requiring detailed imaging and consistent geometric reproduction, provided the complete camera system is properly calibrated.

Q: Can TOWIN customize this M12 machine vision lens?
A: TOWIN can support OEM and ODM optical projects based on requirements such as sensor format, focal length, FOV, working distance, mounting interface, and mechanical configuration.

Lens Selection Resources

For a 35mm machine vision lens, selecting the correct sensor size and working distance is especially important because the focal length produces a relatively narrow field of view. TOWIN’s Lens Selection Guide provides additional guidance for matching lens parameters with camera requirements.

You can also use the FOV Calculator to estimate the required viewing area based on the camera’s sensor and installation distance.
