Low Distortion Lens – M702114008226

M702114008226 is Low distortion Wide-angle CCTV lens with 1/4″ format, 2.1mm focal length, 90° diagonal FOV, 2-Megapixel, F2.6 aperture, and 2G3P optical structure.

2.1mm M7 Low Distortion Lens

This 2.1mm M7 low distortion wide angle lens is a compact fixed focal lens designed for miniature camera modules requiring broad scene coverage and extremely low geometric distortion. With a 90° diagonal FOV on the OV9732 1/4″ sensor and TV distortion below -0.5%, it provides wide-area imaging while maintaining excellent image geometry. Its M7 × 0.35 mount, fixed F2.6 aperture, and 9.85mm TTL make it well suited for space-constrained embedded camera systems.

2.1mm M7 Low Distortion Lens Applications

Core Application Scenes

This 2.1mm M7 low distortion lens is designed for compact camera systems where wide scene coverage and accurate image geometry are both important. Its 90° diagonal field of view allows a small 1/4″ camera module to capture a relatively broad area, while the TV distortion of less than -0.5% helps reduce the curved-line effect commonly associated with wider-angle optics.

The lens is particularly suitable for embedded vision modules, compact IoT cameras, miniature monitoring devices, robotic sensing modules, and electronic equipment with limited installation space. Its M7 × 0.35 interface and 9.85mm total track length make it appropriate for optical assemblies where the available mechanical envelope is restricted.

The 0.2m minimum object distance also makes the lens practical for relatively close-range imaging. This can be valuable for compact devices that need to observe nearby objects, equipment status, operating areas, or user interactions without requiring a physically large camera assembly.

For applications where image geometry matters, the combination of wide FOV and very low distortion can help maintain more natural spatial representation across the captured scene. Engineers evaluating similar miniature optics can also compare sensor size, focal length, and field of view through Towin’s Lens Selection Guide.

Frequently Asked Questions

Q: What type of lens is this 2.1mm M7 lens?
A: It is a fixed focal wide angle lens with a 2.1mm focal length, 90° diagonal FOV, and extremely low TV distortion of less than -0.5%.

Q: Is this 2.1mm lens a fisheye lens?
A: No. Although the lens provides a wide 90° diagonal field of view, its TV distortion is specified below -0.5%. This makes it more appropriately classified as a low distortion wide angle lens rather than a fisheye lens.

Q: What sensor is this lens designed for?
A: The specified FOV is based on the OV9732 sensor with a 1/4″ image format and 2MP resolution.

Q: What is the field of view of the 2.1mm M7 lens?
A: On the specified OV9732 sensor, the lens provides a 90° diagonal, 82° horizontal, and 52° vertical field of view.

Q: What is the advantage of the < -0.5% TV distortion?
A: The very low distortion helps preserve the geometric shape of objects across the image and reduces visible bending of straight lines, which is useful in compact wide-angle imaging applications.

Q: What does the M7 × 0.35 mount mean?
A: M7 × 0.35 identifies the lens mounting thread, with a 7mm nominal thread diameter and 0.35mm thread pitch. It is commonly used for compact miniature camera assemblies.

Q: What is the minimum object distance of this lens?
A: The specified minimum object distance is 0.2m, making the lens suitable for relatively close-range imaging as well as general compact camera applications.

Q: Can this lens be customized for a different camera module?
A: Custom optical and mechanical configurations can be evaluated according to the required sensor, focal length, FOV, mounting interface, dimensions, and application. For project-specific requirements, engineers can contact Towin for customization consultation.
