2mm M5 Miniature Low Distortion Lens Applications

Compact Machine Vision

The combination of a 2mm focal length, 84° diagonal FOV, and less than 1.5% distortion makes this lens suitable for compact machine vision systems that require a wider viewing area without the pronounced geometric distortion associated with fisheye optics.

Typical applications include:

• Compact machine vision cameras
• Embedded inspection modules
• Small industrial cameras
• Component inspection systems
• Compact robotic vision modules
• Edge AI imaging devices
• Automated equipment monitoring

Designed for compact machine vision applications requiring wide coverage with controlled geometric distortion.

Low-Distortion Wide-Angle Imaging

Unlike an extreme fisheye lens, this optical design combines a relatively wide 84° diagonal FOV with <1.5% TV distortion. This makes it useful when a system needs to capture a relatively large area while preserving more natural image geometry.

For applications where distortion is an important optical selection parameter, the Distortion Guide can help engineers evaluate different lens designs.

The lens can also be considered alongside TOWIN’s Low Distortion Lens collection when selecting a compact lens for geometry-sensitive imaging.

Embedded Camera Modules

The 3mm T.T.L. and 0.6mm M.B.F.L. provide a highly compact optical package. Combined with the M5×0.25 mount, this lens is suitable for camera modules where lens size and installation depth are important mechanical constraints.

Potential device integrations include:

• Miniature embedded cameras
• Compact inspection modules
• Small-format AI cameras
• Robotic end-effectors
• Electronic equipment monitoring cameras
• Space-constrained imaging assemblies

For engineers matching this lens to a sensor, TOWIN’s Sensor Guide provides useful information about sensor format and lens compatibility.

Wide-Area Close-Range Imaging

With an M.O.D. of 0.1m, the lens can be used for relatively close-range imaging while maintaining a wide field of view. This combination is useful when the camera must observe nearby objects without requiring a large installation distance.

The F2.4 fixed aperture provides a consistent optical configuration for applications where adjustable iris control is not required.

Frequently Asked Questions

Q: What sensor size is this 2mm M5 lens designed for?
A: The lens is designed for 1/5″ image sensors and provides an 84° diagonal, 70° horizontal, and 55° vertical field of view.

Q: Is this lens a fisheye lens?
A: No. Although the 2mm focal length provides a wide field of view, its TV distortion is less than 1.5%, which makes it more appropriate to classify as a low distortion wide-angle lens rather than a fisheye lens.

Q: What makes this a low distortion lens?
A: The specified TV distortion of <1.5% provides controlled image geometry, which can be beneficial for inspection and vision applications where excessive barrel distortion could affect image interpretation.

Q: What is the advantage of the 84° field of view?
A: The 84° diagonal FOV allows the camera to cover a relatively large scene from a compact installation position while avoiding the extreme distortion associated with much wider fisheye optics.

Q: What is the total track length of this miniature lens?
A: The specified T.T.L. is only 3mm, making it suitable for highly compact camera modules and embedded optical systems.

Q: What does M.B.F.L. 0.6mm mean for camera integration?
A: The 0.6mm M.B.F.L. indicates a very short back focal length, which can help accommodate compact sensor and mechanical layouts.

Q: Does the 3P+IRCF structure mean the lens is IR corrected?
A: No. IRCF refers to an IR Cut Filter configuration. It should not be interpreted as an IR-corrected optical design.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.1m, making it suitable for relatively close-range imaging applications.
