Low Distortion Lens – S36011801124F

S36011801124F-Low distortion fixed-iris 8MP M12-mount lens with 36mm focal length, <0.7% distortion, F2.4 1/1.8″ & 1/2.3″ industrial CCTV lens.

M12 Low Distortion Lens

This 36mm 8MP M12 low distortion lens is designed for narrow-field imaging where accurate target framing and controlled geometric distortion are important. With a 14.5° diagonal FOV on a 1/1.8″ sensor, less than 0.7% distortion, and 8MP resolution, it provides a focused imaging solution for compact industrial cameras, machine vision systems, and fixed-position monitoring applications.

Its 36mm fixed focal length is particularly suitable for systems that need to isolate a specific target or observe objects from a relatively long working distance without using a wide-angle optical design.

M12 Low Distortion Lens Core Highlights

• <0.7% Low Distortion: Maintains controlled image geometry for accurate target representation.
• 36mm Fixed Focal Length: Provides focused narrow-field imaging for localized targets.
• 8MP High Resolution: Supports detailed image capture for advanced compact vision systems.
• 1/1.8″ Sensor Support: Provides a 14.5° diagonal FOV with larger-format imaging sensors.
• 1m Minimum Object Distance: Suitable for applications where the camera observes targets from a defined working distance.

M12 Low Distortion Lens Applications

Core Application Scenes

This 36mm M12 low distortion lens is optimized for applications that require a focused view of a specific target rather than broad scene coverage. Its 14.5° diagonal FOV on a 1/1.8″ sensor allows the camera to concentrate on a localized area, while the <0.7% distortion specification helps preserve the target’s geometric appearance.

For longer-distance industrial observation, the 36mm focal length can be used to monitor specific equipment, components, or production zones when the camera cannot be positioned close to the target. The 1m minimum object distance makes it particularly relevant to fixed installations where a defined camera-to-object distance is maintained.

In machine vision and automated inspection, this lens can support applications where a relatively narrow field of view is required to isolate a particular inspection area. The combination of 8MP resolution and low distortion is useful when image detail and consistent object geometry are both important. Engineers can explore TOWIN’s Machine Vision solutions for related industrial imaging applications.

The lens can also be used for localized industrial monitoring, such as observing machinery status, production details, specific workstations, or restricted equipment areas. Its narrow viewing angle helps reduce unnecessary background information and concentrates the camera’s imaging resources on the target zone.

For compact embedded vision systems, the M12x0.5 mount provides a practical integration option where a longer focal length is needed but the camera assembly must remain compact. The lens can be incorporated into specialized camera modules for target recognition, equipment observation, and other fixed-position imaging applications.

Because the distortion is specified below 0.7%, this lens is better suited to applications where geometric consistency matters than conventional wide-angle optics. TOWIN’s Distortion Guide provides additional information for evaluating distortion requirements during lens selection.

Frequently Asked Questions

Q: What type of lens is this?

A: This is a 36mm 8MP M12 low distortion fixed focal lens designed for narrow-field imaging. It provides a 14.5° diagonal FOV on a 1/1.8″ sensor and less than 0.7% distortion.

Q: What sensor sizes can this M12 lens support?

A: The lens is specified with a maximum image format of Φ10.3mm and provides FOV data for both 1/1.8″ and 1/2.3″ sensors. The actual camera configuration should be verified based on the sensor’s image circle.

Q: What is the field of view of the 36mm lens?

A: On a 1/1.8″ sensor, the lens provides a 14.5° diagonal, 11.7° horizontal, and 8.8° vertical FOV. On a 1/2.3″ sensor, the corresponding FOV is 12.5° diagonal, 10° horizontal, and 7.5° vertical.

Q: Is this a low distortion lens?

A: Yes. The specified distortion is less than 0.7%, making this lens suitable for applications where controlled image geometry is important.

Q: What applications are suitable for a 36mm M12 lens?

A: The lens is suitable for localized industrial inspection, machine vision, equipment monitoring, target recognition, and fixed-position embedded vision systems that require a relatively narrow field of view.

Q: Is this lens suitable for wide-angle imaging?

A: No. Its 14.5° diagonal FOV on a 1/1.8″ sensor is designed for narrow-field target imaging rather than wide-area scene coverage. A shorter focal length would generally be more appropriate when a wider field of view is required.

Q: Does the lens have an adjustable iris or zoom?

A: The lens uses a fixed iris and fixed 36mm focal length. It is therefore designed as a fixed focal optical solution rather than a varifocal or zoom lens.

Optical Selection Resources

Selecting a 36mm lens requires careful consideration of sensor size, working distance, target dimensions, and required field of view. TOWIN’s FOV Calculator can help estimate the scene coverage for a specific camera configuration, while the Focal Length Calculator can assist with focal-length selection.

For sensor compatibility, refer to the Sensor Guide. Engineers comparing different optical configurations can also review the Lens Selection Guide for practical lens selection considerations.
