Low Distortion Lens – S50011809028

S50011809028-Low distortion fixed-focus 12MP 1/1.8″ M12 HD lens with 50mm long focal length, 10° diagonal FOV, F2.8 aperture for general imaging applications.

50mm Ultra Low Distortion Lens

This 50mm 12MP M12 ultra-low distortion lens is designed for high-resolution, narrow-field imaging where precise target representation and excellent geometric control are required. With less than 0.1% distortion, a 10° diagonal FOV, and 12MP resolution, it provides a strong optical solution for precision inspection, machine vision, target recognition, and fixed-position industrial imaging.

The 50mm fixed focal length concentrates the camera’s field of view on a specific target area, making this lens particularly suitable for applications where detailed imaging is required from a defined working distance.

• 12MP High Resolution: Captures fine target details for demanding inspection and recognition systems.
• 50mm Fixed Focal Length: Delivers a narrow 10° diagonal FOV for focused target imaging.
• 1/1.8″ Sensor Support: Designed for high-resolution imaging systems using 1/1.8″ image sensors.
• M12x0.5 Mount: Combines a long focal length with a compact M12 mechanical interface.

Ultra Low Distortion Lens Applications

Core Application Scenes

This 50mm M12 low distortion lens is optimized for imaging applications where a specific target must be captured with high detail and minimal geometric deformation. Its 10° diagonal field of view provides a focused perspective, while the <0.1% distortion specification helps maintain accurate target geometry throughout the image.

For precision industrial inspection, the lens can be used when the camera needs to examine a localized component, feature, or measurement area without capturing excessive surrounding information. Its 12MP resolution provides additional image detail for identifying small features, surface characteristics, markings, and other visual information in fixed inspection environments.

The combination of 50mm focal length and ultra-low distortion also makes the lens suitable for machine vision systems that require stable image geometry. It can support applications such as dimensional observation, component positioning, fine-detail inspection, and automated visual recognition where excessive lens distortion could affect image interpretation. See TOWIN’s Machine Vision solutions for more information about industrial vision applications.

For longer-distance target observation, the narrow FOV allows the camera to concentrate on a defined target area while reducing unnecessary background content. This makes the lens suitable for fixed-position monitoring of equipment, production details, inspection stations, and other localized industrial targets.

The lens can also be integrated into compact high-resolution embedded vision systems where a longer focal length is required but the camera design still benefits from an M12x0.5 interface. Its manual focus configuration allows the optical focus to be adjusted during system integration according to the actual working distance.

With distortion below 0.1%, this lens is particularly relevant when geometric accuracy is an important part of the imaging requirement. Engineers can refer to TOWIN’s Distortion Guide when evaluating the effect of optical distortion on their specific application.

Q: What is the distortion level of this 50mm M12 lens?

A: The specified distortion is less than 0.1%, providing exceptionally controlled geometric imaging for applications where image shape and positional accuracy are important.

Q: What sensor size does this lens support?

A: The lens is specified for a 1/1.8″ image format and is designed for high-resolution imaging systems using compatible 1/1.8″ sensors.

Q: What is the field of view of the 50mm lens?

A: The lens provides a 10° diagonal, 9° horizontal, and 5° vertical field of view on a 1/1.8″ sensor, giving it a narrow and focused imaging perspective.

Q: What applications are suitable for a 50mm M12 lens?

A: It is suitable for precision industrial inspection, machine vision, detailed target recognition, fixed-position equipment monitoring, and other applications requiring high resolution and very low optical distortion.

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

A: No. Its 10° diagonal FOV is designed for narrow-field target imaging rather than wide-area coverage. A shorter focal length would generally be more appropriate when a wider field of view is required.

Q: Does the lens support manual focus?

A: Yes. The lens uses manual focus, allowing the focus position to be adjusted during camera integration according to the working distance and target position.

Q: Is the aperture adjustable?

A: No. The lens uses a fixed F2.8 aperture and fixed iris configuration. This provides a straightforward optical configuration for dedicated imaging systems.

Optical Selection Resources

Selecting a 50mm M12 lens requires careful consideration of sensor size, working distance, target dimensions, and required field of view. TOWIN’s FOV Calculator can help estimate the viewing coverage for a specific camera configuration.

For focal-length selection, the Focal Length Calculator can help engineers determine an appropriate focal length based on sensor dimensions, working distance, and target field of view.

Engineers can also refer to the Sensor Guide when matching the lens to a camera sensor, while the Lens Selection Guide provides additional guidance for evaluating focal length, sensor format, and application requirements.
