5.8mm M8 Low Distortion Lens Applications

Core Application Scenes

This 5.8mm M8 low distortion lens is designed for compact camera systems that require a balance between field of view, image resolution, and optical size. Its 63° diagonal FOV provides useful scene coverage for close- to medium-range imaging, while the controlled distortion helps maintain more consistent object geometry across the captured image.

The lens is well suited to compact machine vision modules, embedded inspection cameras, robotic visual sensors, smart electronic equipment, and miniature industrial imaging devices. With support for 1/2.7″ sensors and 5MP resolution, it can provide detailed image capture without requiring a large optical assembly.

The 0.1m minimum object distance makes the lens particularly useful for equipment positioned relatively close to the target. This can benefit compact inspection modules used for component recognition, assembly verification, object positioning, and localized visual inspection.

Its M8 × 0.35 mount and 10.3mm TTL are important advantages when mechanical space is limited. The 4.9mm BFL also provides a defined optical mounting reference for camera module integration. The 5G + IRCF construction is suitable for camera designs incorporating an IR-cut filter within the optical assembly.

For embedded systems that operate under controlled visible-light conditions, the integrated IRCF can help maintain natural-color imaging by filtering unwanted infrared wavelengths. This makes the lens suitable for compact camera modules where optical performance and mechanical integration need to be considered together.

Designed for compact machine vision, embedded inspection, and space-constrained industrial imaging applications.

Frequently Asked Questions

Q: What type of lens is the 5.8mm M8 lens?
A: It is a fixed focal, low distortion miniature lens designed for 1/2.7″ sensors and 5MP imaging applications.

Q: Is this lens a fisheye lens?
A: No. The 63° diagonal FOV does not represent a fisheye optical design. The lens is better classified as a compact low distortion fixed focal lens.

Q: What is the field of view of this 5.8mm lens?
A: When used with a 1/2.7″ sensor, the lens provides approximately 63° diagonal, 55° horizontal, and 32° vertical FOV.

Q: What does the < -5.5% distortion specification mean?
A: It indicates that the lens has controlled geometric distortion compared with highly distorted ultra-wide optical designs. This can be beneficial in visual recognition, inspection, positioning, and other imaging applications where object geometry matters.

Q: What sensor size is this M8 lens designed for?
A: The lens is specified for a 1/2.7″ image format and supports 5MP resolution.

Q: What is the function of the IRCF in this lens?
A: IRCF generally refers to an infrared-cut filter. It helps block unwanted infrared wavelengths from reaching the image sensor, supporting more consistent visible-light color reproduction in suitable camera systems. It should not be interpreted as an IR-corrected optical design unless IR correction is separately specified.

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

Q: What are the advantages of the M8 × 0.35 mount?
A: The M8 × 0.35 interface provides a compact mounting solution for miniature camera modules, embedded vision devices, and equipment where the available optical installation space is limited.
