1.2mm M6.5 Low Distortion Wide Angle Lens Applications

Core Application Scenes

This 1.2mm low distortion wide angle lens is designed for compact camera systems that need a broad field of view while maintaining more controlled image geometry than an extreme fisheye configuration. Its 110° diagonal FOV on a 1/6″ sensor provides extensive scene coverage without requiring a physically large optical assembly.

The lens is particularly suitable for embedded vision modules, compact smart cameras, IoT imaging devices, robotic sensing modules, and short-range monitoring equipment. Its 0.2 m minimum object distance adds flexibility for systems that mount the camera relatively close to the monitored area.

The 1.2mm focal length and M6.5 × 0.25 mounting interface make the lens suitable for compact optical assemblies where both wide-angle coverage and mechanical integration need to be considered. The fixed F2.4 aperture also provides a straightforward optical configuration for camera modules that do not require variable iris control.

The < -7.9% TV distortion specification is an important characteristic for applications that need a wide field of view while seeking more controlled geometric deformation than a strongly distorted fisheye image. It therefore fits visual systems that balance broad coverage with usable image geometry.

The 4G2P optical structure with integrated IRCF is suitable for visible-light camera modules that require infrared filtering as part of the optical assembly.

Designed for compact wide-area imaging where broad FOV and controlled distortion need to be balanced.

When selecting a wide angle lens, sensor format, focal length, and field of view should be evaluated together. Towin’s Sensor Guide explains the relationship between sensor specifications and lens selection, while the Lens Selection Guide provides additional guidance for comparing focal length, FOV, optical format, and other parameters.

Because this lens is designed around controlled distortion rather than extreme fisheye imaging, the Distortion Guide can help engineers understand how different distortion levels affect image geometry and lens selection.

For initial optical calculations, the FOV Calculator can be used to estimate viewing coverage based on sensor size and focal length.

Frequently Asked Questions

Q: What type of lens is the 1.2mm M6.5 lens?
A: It is a wide angle fixed focal lens with a controlled-distortion design, intended for compact camera modules using 1/5″ or 1/6″ sensors.

Q: Is this lens a fisheye lens?
A: No. Although it provides a 110° diagonal FOV on a 1/6″ sensor, its optical positioning is better described as a wide angle lens with controlled distortion rather than a fisheye lens.

Q: What is the field of view of this lens?
A: On the specified 1/6″ sensor, the lens provides approximately 110° diagonal, 94° horizontal, and 75° vertical field of view.

Q: What does the < -7.9% TV distortion specification mean?
A: It indicates that the lens has controlled barrel-type image distortion while maintaining a wide field of view. The specification is useful when balancing broad scene coverage with image geometry.

Q: What sensor formats are supported?
A: The lens is specified for both 1/5″ and 1/6″ image formats, with the listed FOV values provided for the 1/6″ format.

Q: What is the minimum object distance of this lens?
A: The M.O.D. is 0.2m, making the lens suitable for relatively close-range imaging applications.

Q: What is the purpose of the IRCF?
A: IRCF stands for infrared cut filter. It helps block unwanted infrared wavelengths from reaching the image sensor and is commonly used in visible-light camera modules.

Q: What mounting interface does this lens use?
A: The lens uses an M6.5 × 0.25 mounting thread and has a total track length of 9.33mm, providing defined mechanical parameters for compact camera integration.
