4.8mm M12 Low Distortion Lens Applications

Core Application Scenes

The 4.8mm focal length provides a 74° diagonal field of view on a 1/2.5″ sensor, making this lens suitable for compact imaging systems that need relatively broad scene coverage while maintaining low geometric distortion.

Its <0.5% distortion specification is particularly useful for machine vision tasks where the shape and position of objects need to remain visually consistent across the image. Typical applications include component inspection, object positioning, dimensional checking, barcode reading, and automated visual monitoring.

The 21.7mm total track length and M12x0.35 mount are well suited to space-constrained camera assemblies. With a 0.2m minimum object distance, the lens can also be used in relatively close-range inspection setups where the camera must be installed near the target.

Typical application scenarios include:

• Compact machine vision inspection
• Industrial component inspection
• Automated optical inspection
• Object positioning and alignment
• Barcode and code inspection
• Embedded machine vision cameras
• Robotic vision systems
• Smart factory monitoring
• Compact AI vision devices
• Industrial equipment monitoring

For engineers selecting a lens according to sensor format, focal length, and field of view, TOWIN’s Sensor Guide provides useful background on sensor and lens compatibility. The Lens Selection Guide can also help compare key optical parameters.

Compatible Devices

This lens can be considered for:

• 1/2.5″ industrial cameras
• M12-mount board cameras
• Compact machine vision cameras
• Embedded vision modules
• AI vision camera modules
• Robotic inspection cameras
• Compact industrial imaging devices
• Automated inspection equipment

Before integration, the camera sensor’s actual active area should be checked against the specified 1/2.5″ image format to ensure the desired image coverage.

Designed for compact machine vision and industrial imaging applications requiring broad scene coverage with controlled geometric distortion.

Frequently Asked Questions

Q1: What type of lens is the 4.8mm M12 lens?
A: It is a fixed focal M12 lens designed for compact imaging applications, with a 1/2.5″ image format, 5MP resolution, and distortion below 0.5%.

Q2: Is this a low distortion M12 lens?
A: Yes. The specified distortion is less than 0.5%, making it suitable for imaging applications where relatively accurate object geometry is important.

Q3: What is the field of view of this lens?
A: The specified field of view is 74° diagonal, 62° horizontal, and 49° vertical.

Q4: Is this lens a fisheye lens?
A: No. The 74° diagonal field of view does not by itself indicate a fisheye design. With distortion specified below 0.5%, this lens is better positioned as a low distortion M12 lens.

Q5: What sensor format does this lens support?
A: The specified image format is 1/2.5″. The actual sensor dimensions should be checked during system integration to confirm the required coverage.

Q6: What is the minimum object distance?
A: The specified MOD is 0.2m, or 200mm.

Q7: What does M12x0.35 mean?
A: M12x0.35 specifies the lens mounting thread, with a nominal 12mm thread diameter and 0.35mm thread pitch. The camera housing should use a matching thread for proper mechanical integration.

Q8: Does IRCF mean the lens is IR corrected?
A: Not necessarily. IRCF indicates an IR-cut filter-related optical configuration, but it should not automatically be interpreted as an IR-corrected lens. This product should therefore not be categorized as an IR Corrected Lens unless IR correction is specifically confirmed.
