M7 1.9mm Low Distortion Miniature Lens

This 1.9mm M7 miniature lens is designed for compact camera modules requiring controlled geometric distortion and a wide 70° diagonal field of view. With VGA resolution, a fixed F2.8 aperture, and less than 1% distortion, it provides a compact optical solution for embedded vision and space-constrained imaging systems.

When selecting a miniature lens, sensor format and field of view should be considered together. The Sensor Guide provides useful information for evaluating sensor and lens compatibility.

M7 Low Distortion Lens Core Highlights

• Low Distortion <1%: Helps maintain accurate image geometry for embedded vision applications.
• 70° Diagonal FOV: Provides broad scene coverage from a compact 1.9mm optical design.
• Compact M7 Mount: M7 × 0.35 thread supports miniature camera assemblies.
• Short 5.7mm M.T.L.: Facilitates integration into space-constrained optical systems.
• High Relative Illumination: >68% relative illumination helps maintain useful brightness across the image field.

M7 1.9mm Low Distortion Lens Applications

Core Application Scenes

This M7 1.9mm low distortion lens is designed for compact imaging systems where a relatively broad field of view is required without the strong geometric distortion associated with fisheye optics. Its 70° diagonal FOV provides wide scene coverage while the distortion remains below 1%, making it suitable for applications where the shape and position of objects need to remain visually consistent across the image.

The 0.1m minimum object distance also makes this lens suitable for relatively close-range imaging inside compact equipment. Its 5.7mm mechanical track length and 0.7mm back focal length provide flexibility for camera modules where available optical space is limited.

The 4P + IRCF structure can support compact camera designs requiring an integrated optical configuration. For engineers working with small CMOS sensors, the Lens Selection Guide can help evaluate focal length, sensor format, field of view, and application requirements together.

Frequently Asked Questions

Q: What is the focal length of this M7 lens?
A: This miniature lens has a fixed 1.9mm focal length and provides a 70° diagonal field of view on the specified 1/6.5″ image format.

Q: Is this M7 lens a low distortion lens?
A: Yes. Its specified distortion is below 1%, making it suitable for applications where controlled image geometry is important.

Q: What sensor format is this lens designed for?
A: The lens is designed for a 1/6.5″ image format and provides VGA resolution.

Q: What is the field of view of the 1.9mm lens?
A: The specified FOV is 70° diagonal, 53° horizontal, and 33° vertical.

Q: Is this lens a fisheye lens?
A: No. The 70° diagonal FOV and distortion below 1% indicate a controlled wide-view optical design rather than a typical fisheye configuration.

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

Q: What does the 4P + IRCF structure mean?
A: The optical structure consists of four lens elements with an IRCF configuration. The supplied specifications do not define a specific IR correction wavelength range, so application-specific IR performance should be confirmed according to the camera module requirements.

Q: Can this M7 lens be used for machine vision applications?
A: Yes. Its compact M7 mounting format, low distortion, 70° diagonal FOV, and fixed focal length make it suitable for miniature machine vision and embedded imaging modules.
