Low Distortion Lens – S07711805120F

S07711805120F is 8-Megapixel low distortion 1/1.8″ M12/S-Mount CCTV lens with Built-In IR Filter, 61° F.O.V. F2.0 for security surveillance.

1/1.8″ Industrial 7.7mm M12 Low Distortion Lens

This 7.7mm M12 lens is an 8MP fixed focal lens designed for 1/1.8″ image sensors, delivering a 61° diagonal field of view and less than -1.9% distortion. With an F2.0 aperture, 0.1m minimum object distance, and integrated IR cut filter, it provides a practical optical solution for compact industrial cameras, inspection systems, and embedded vision devices requiring detailed and geometrically controlled images.

Product Highlights at a Glance

• 7.7mm fixed focal length for stable and repeatable imaging
• 8MP resolution for detailed image capture with 1/1.8″ sensors
• Low distortion < -1.9% helps preserve object geometry in the captured image
• F2.0 aperture provides a strong balance between optical performance and compact system integration
• Integrated IRCF helps provide visible-light imaging by filtering unwanted infrared wavelengths

7.7mm M12 Low Distortion Lens Applications

Core Application Scenes

The 7.7mm focal length provides a moderate field of view of 61° diagonally on a 1/1.8″ sensor, making this lens suitable for camera systems that need useful scene coverage while maintaining controlled image geometry. The < -1.9% distortion specification is particularly relevant to inspection and recognition systems where excessive image bending could affect visual measurement or object positioning.

Its 8MP resolution makes the lens suitable for higher-detail imaging than conventional 5MP compact lenses, while the F2.0 aperture supports practical light collection in indoor industrial environments. The 0.1m minimum object distance also allows the lens to be positioned relatively close to the target in compact inspection equipment.

The integrated IR cut filter (IRCF) is intended to block infrared wavelengths during visible-light imaging. It should not be confused with an IR-corrected optical design; applications requiring day/night or near-infrared imaging should be evaluated separately.

Frequently Asked Questions

Q: What sensor size is this 7.7mm M12 lens designed for?
A: The lens is designed for 1/1.8″ image sensors, with a maximum image format of Φ11.

Q: What is the field of view of the 7.7mm lens?
A: On a 1/1.8″ sensor, the field of view is 61° diagonal, 51° horizontal, and 39° vertical.

Q: Is this an 8MP M12 lens?
A: Yes. The lens is specified for 8MP resolution and is designed for use with 1/1.8″ sensors.

Q: Is the 7.7mm M12 lens a low distortion lens?
A: Yes. Its specified distortion is less than -1.9%, making it suitable for imaging applications where controlled geometric distortion is important.

Q: What does IRCF mean on this lens?
A: IRCF refers to an infrared cut filter. It filters infrared wavelengths for visible-light imaging. An IRCF should not be interpreted as an IR-corrected optical design.

Q: What is the minimum object distance?
A: The minimum object distance is 0.1m, allowing the lens to support relatively close-range imaging configurations.

Q: What mount does this lens use?
A: This lens uses an M12x0.5 threaded mount, which is commonly used in compact industrial and embedded camera systems.

Q: Is this lens suitable for machine vision?
A: It can be used in machine vision and automated inspection systems requiring 8MP imaging, a 1/1.8″ sensor format, moderate field of view, and controlled distortion. Final selection should be based on the required working distance, object size, sensor characteristics, and field of view.
