Low Distortion Lens – S50023001080

S50023001080-12MP Low Distortion Megapixel Lens M12-mount lens with 50mm focal length, suitable for 2/3″ and 1/2″ sensors, F8.0 aperture, <0.3% distortion, and 0.3m M.O.D.

50mm M12 Low Distortion Lens

This 50mm 12MP M12 low distortion lens is designed for fixed-position imaging systems that require high resolution, controlled geometric distortion, and a narrow field of view. Supporting up to a 2/3″ image format with less than 0.3% distortion, this fixed focal lens is well suited for industrial inspection, factory automation, machine vision, and detailed target observation.

Its F8.0 aperture provides a relatively narrow optical aperture that can help support greater depth of field in fixed imaging configurations, making the lens particularly suitable for inspection environments where multiple target features need to remain within an acceptable focus range.

Low Distortion Lens Core Highlights

• <0.3% Low Distortion: Provides controlled geometric imaging for inspection and recognition applications.
• 12MP High Resolution: Supports detailed image acquisition for demanding industrial vision systems.
• 2/3″ Image Format: Offers compatibility with larger machine vision sensors than many compact M12 optics.
• 50mm Fixed Focal Length: Provides a focused narrow field of view for localized target imaging.
• F8.0 Aperture: Supports depth-of-field-oriented imaging configurations for fixed inspection environments.

Low Distortion Lens Applications

Core Application Scenes

This 50mm M12 machine vision lens is designed for fixed imaging systems where the camera needs to concentrate on a defined inspection area rather than capture a broad scene. Its 12.6° diagonal FOV on a 2/3″ sensor provides a focused perspective, while the <0.3% distortion specification helps maintain consistent geometric representation across the image.

For factory automation and production-line inspection, the lens can be used to observe specific components, assemblies, markings, or product features from a controlled camera position. The 50mm focal length helps isolate the inspection target from surrounding areas, while the F8.0 aperture can be beneficial in fixed setups where maintaining a useful depth of field is important. For broader automation applications, see TOWIN’s Machine Vision solutions.

The lens is also suitable for precision component inspection, particularly where the camera needs to cover a defined area while maintaining low geometric distortion. Applications may include checking component placement, product appearance, mechanical features, printed markings, and other localized visual characteristics.

For automated optical inspection systems, the combination of 12MP resolution and <0.3% distortion provides a useful balance between image detail and geometric control. The larger 2/3″ image format also allows the lens to work with camera systems using larger sensors, provided the sensor’s image circle remains within the specified optical coverage.

The lens can be considered for fixed-position equipment monitoring when the objective is to continuously observe a specific machine component or operating zone rather than an entire room or production floor. Its narrow FOV helps concentrate the captured image on the selected target area.

For engineers selecting between different focal lengths and sensor formats, TOWIN’s Lens Selection Guide can help compare optical requirements. The Distortion Guide is also useful when evaluating whether a low-distortion lens is appropriate for a particular inspection task.

Frequently Asked Questions

Q: What type of lens is this?

A: This is a 50mm 12MP M12 low distortion fixed focal lens designed for industrial imaging, machine vision, and factory automation applications requiring a narrow field of view and controlled geometric distortion.

Q: What sensor size does this 50mm M12 lens support?

A: The lens has a maximum image format of Φ11.3mm and provides specified FOV data for both 2/3″ and 1/2″ sensors. The 2/3″ configuration provides a 12.6° diagonal FOV.

Q: What is the distortion of this lens?

A: The specified distortion is less than 0.3%, making the lens suitable for applications where image geometry needs to remain well controlled.

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

A: On a 2/3″ sensor, the lens provides a 12.6° diagonal, 10.1° horizontal, and 7.6° vertical FOV. On a 1/2″ sensor, the corresponding FOV is 9.2° diagonal, 7.3° horizontal, and 5.5° vertical.

Q: Is this lens suitable for machine vision?

A: Yes. Its 12MP resolution, low distortion, 50mm focal length, and narrow FOV make it suitable for fixed-position machine vision and automated inspection systems when the working distance and target size match the optical configuration.

Q: What is the minimum object distance?

A: The specified M.O.D. is 0.3m, making the lens suitable for both close-to-medium working configurations where the target can be positioned at or beyond the specified minimum object distance.

Q: Is this a wide-angle lens?

A: No. With a 12.6° diagonal FOV on a 2/3″ sensor, this is a narrow-field fixed focal lens rather than a wide-angle lens. It is designed to concentrate imaging on a defined target area.

Optical Selection Resources

Selecting a 50mm machine vision lens requires matching the focal length with sensor size, working distance, target dimensions, and required field of view. TOWIN’s FOV Calculator can help estimate the expected image coverage for a specific camera configuration.

The Focal Length Calculator can help engineers determine whether a 50mm focal length is appropriate for their target working distance and sensor dimensions.

For sensor matching, refer to the Sensor Guide. Engineers can also review Lens Basics for fundamental optical concepts when designing or selecting an industrial camera lens.
