2.7mm M7 Low Distortion Lens Applications

Core Application Scenes

This 2.7mm M7 wide angle lens is designed for miniature camera systems that need wider scene coverage without the strong geometric distortion associated with fisheye optics. Its 80° diagonal field of view provides a broad perspective while the less-than-1% distortion specification helps preserve a more natural representation of straight lines and object shapes.

The lens is particularly suitable for compact embedded cameras, smart IoT imaging modules, robotic sensing devices, miniature monitoring equipment, and close-range visual systems. Its 5MP resolution capability provides sufficient image detail for applications where a compact camera needs to capture both the surrounding scene and relatively small visual features.

The 0.1m minimum object distance makes this lens especially useful for close-range imaging. It can be positioned near equipment, objects, or operating areas while maintaining a relatively wide field of view. This characteristic can benefit compact inspection modules, interactive devices, and robotic cameras operating within confined spaces.

The fixed F2.2 aperture and manual-focus configuration are suitable for camera modules where the optical system is installed during assembly and then mechanically adjusted to the required imaging distance. Engineers evaluating this type of lens can use Towin’s Lens Selection Guide to compare focal length, FOV, sensor size, and application requirements.

Designed for compact high-resolution imaging where wide coverage, low distortion, and limited optical space are important.

Frequently Asked Questions

Q: What type of lens is the 2.7mm M7 lens?
A: It is a low distortion wide angle fixed focal lens designed for 1/4″ camera modules, with an 80° diagonal FOV and less than 1% distortion.

Q: Is this 2.7mm M7 lens a fisheye lens?
A: No. The 80° diagonal FOV and less-than-1% distortion specification indicate a controlled wide-angle optical design rather than a fisheye lens.

Q: What sensor size is this lens designed for?
A: The lens is specified for a 1/4″ image format and supports up to 5MP resolution according to the supplied specifications.

Q: What is the field of view of this lens?
A: The specified diagonal field of view is 80°.

Q: What is the advantage of less than 1% distortion?
A: Low distortion helps preserve the geometric shape of objects and reduces visible bending of straight lines, which can be useful for compact imaging systems requiring consistent image geometry.

Q: What is the minimum object distance of the 2.7mm lens?
A: The specified M.O.D. is 0.1m, allowing the lens to capture relatively close subjects.

Q: What does the 1.18mm F.B.L. specification mean?
A: F.B.L., or flange back length, describes the optical distance between the mounting reference and the image-side optical position. It is an important parameter when integrating the lens with a specific camera module.

Q: Can this M7 lens be customized for a different camera module?
A: Custom optical and mechanical configurations can be evaluated according to sensor format, resolution, FOV, distortion, mounting interface, F.B.L., dimensions, and application requirements. For project-specific requirements, engineers can contact Towin for customization support.
