3.0mm M5 Low Distortion Lens Applications

Core Application Scenes

This 3.0mm miniature low distortion lens is designed for compact imaging systems that need a wider viewing area without sacrificing geometric control. With a 61° diagonal field of view and distortion below 1%, it is particularly suitable for applications where objects near the edges of the image need to retain accurate shape and position.

The lens is well suited to embedded inspection cameras installed inside compact equipment. Its 3.2mm total track length allows the optical assembly to fit into camera housings where conventional M12 or larger threaded lenses would require too much installation space.

For miniature automation equipment, the combination of a 3.0mm focal length and low distortion can support visual positioning, component presence inspection, alignment, and monitoring. The relatively high >54% relative illumination is also useful when the system needs consistent image brightness across a compact sensor.

The lens can also be integrated into small robotic vision modules and OEM camera assemblies. Its M5 × 0.35 mount provides a compact mechanical interface, while the 1/5″ image format supports small CMOS imaging modules.

Designed for compact low-distortion inspection, embedded vision, and miniature automation imaging applications.

Low Distortion for Compact Imaging

The lens provides less than 1% distortion, making it particularly useful for compact imaging systems where excessive wide-angle distortion could affect object geometry.

This characteristic is valuable in applications involving visual positioning, dimensional comparison, edge detection, and machine-assisted inspection. Compared with highly distorted wide-angle or fisheye designs, the controlled distortion profile can simplify downstream image processing when maintaining geometric consistency is important.

Engineers evaluating different distortion levels can refer to the Distortion Guide when determining how lens distortion may affect their imaging system.

Optical Construction

The lens uses a 2P + IRCF optical construction. The IRCF specification indicates an integrated IR-cut filter configuration for visible-light imaging. It should not be interpreted as an IR-corrected optical design.

The combination of 3.2mm T.T.L., M5 × 0.35 mount, 61° diagonal FOV, and <1% distortion makes this lens particularly suitable for applications requiring a compact optical path with controlled image geometry.

Frequently Asked Questions

Q: What sensor size is this 3.0mm lens designed for?
A: This lens is designed for 1/5″ image sensors and supports a maximum image circle of approximately Φ3.8mm.

Q: What is the field of view of this lens?
A: The lens provides a 61° diagonal FOV, 50° horizontal FOV, and 40° vertical FOV.

Q: Is this a low distortion lens?
A: Yes. The specified distortion is below 1%, making it suitable for imaging applications where controlled image geometry is important.

Q: Is this lens a fisheye lens?
A: No. The 61° diagonal field of view and less-than-1% distortion are characteristic of a controlled wide-angle design rather than a fisheye lens.

Q: What mount does the lens use?
A: The lens uses an M5 × 0.35 mount, which is intended for miniature camera modules and compact embedded imaging systems.

Q: How compact is this lens?
A: The total track length is only 3.2mm, allowing the lens to be integrated into camera modules with very limited optical installation depth.

Q: What does IRCF mean in the optical construction?
A: IRCF refers to an IR-cut filter configuration. It indicates filtering for visible-light imaging but does not mean that the lens is an IR-corrected lens.

Q: What applications are suitable for this low distortion miniature lens?
A: The lens is suitable for compact inspection cameras, embedded industrial imaging, miniature robotics cameras, visual positioning, and OEM camera modules where low distortion and a small optical footprint are required.
