M5 Miniature Low Distortion Lens Core Highlights

• Less Than 1.5% Distortion — Maintains controlled image geometry for compact imaging applications requiring accurate scene representation.
• 2.2mm Short Focal Length — Provides broad 80° diagonal coverage from a very small optical package.
• Ultra-Compact M5×0.35 Mount — Supports integration into miniature camera modules where installation space is highly restricted.
• Megapixel Optical Performance — Designed for detailed imaging in compact embedded vision systems.
• Integrated IR Cut Filter — The 3P optical construction includes an IR cut filter for visible-light imaging configurations.

M5 Miniature Low Distortion Lens Applications

This 2.2mm M5 lens is designed for compact imaging applications where both small mechanical dimensions and controlled optical distortion are important. Unlike extreme fisheye optics, its less-than-1.5% distortion provides a much more controlled image geometry while still delivering an 80° diagonal field of view.

Low-Distortion Machine Vision

The <1.5% distortion specification is one of the main optical advantages of this lens. It provides a significantly more controlled perspective than highly distorted fisheye designs while retaining a relatively broad 80° diagonal FOV.

This makes the lens suitable for compact machine vision modules used for object observation, visual inspection, positioning, and localized industrial imaging where excessive geometric distortion could affect image interpretation.

Robotics & Compact Perception Modules

Small robotic platforms and embedded perception devices often have strict limitations on camera size. The M5 mount allows the optical assembly to fit into compact camera housings while the 63° horizontal FOV provides useful coverage of the working area.

Potential applications include miniature robotic cameras, compact inspection robots, robotic end-effectors, and embedded perception modules.

More robotic imaging applications can be found in TOWIN’s Robotics Vision solution.

Low-Distortion Optical Performance

For miniature camera systems, increasing the field of view often introduces stronger barrel distortion. This 2.2mm M5 lens takes a more controlled optical approach, providing an 80° diagonal FOV while keeping specified distortion below 1.5%.

This makes it particularly useful when a compact camera requires broad coverage but the image still needs to maintain relatively consistent geometry.

When comparing lenses, focal length, sensor size, field of view, distortion, and mechanical dimensions should be evaluated together. TOWIN’s Lens Selection Guide provides additional guidance for choosing an appropriate optical configuration.

Compact Optical Integration

The M5×0.35 mount is one of the defining characteristics of this lens. Its miniature thread is suitable for applications where the camera housing and optical assembly must remain extremely small.

The lens has a 1.23mm BFL and a minimum object distance of 0.1m, making it suitable for close-range compact imaging configurations when the mechanical and optical conditions are properly matched.

Because the lens uses a fixed F2.8 aperture, fixed iris, manual focus, and fixed zoom configuration, it is intended for camera designs where the optical setup can be established during installation rather than continuously adjusted during operation.

Field of View & Sensor Matching

This lens is designed for a 1/5″ image format and provides an 80° diagonal, 63° horizontal, and 48° vertical field of view under the specified configuration.

Before integrating the lens into a camera system, the sensor format and required scene coverage should be checked together. TOWIN’s Sensor Guide can help with sensor and lens compatibility considerations.

The FOV Calculator can also be used to estimate the viewing area required for a specific working distance and imaging setup.

Frequently Asked Questions

Q: What is the focal length of this M5 lens?
A: The focal length is 2.2mm, providing a relatively broad field of view from a highly compact optical assembly.

Q: What is the field of view of this 2.2mm lens?
A: The specified FOV is 80° diagonal, 63° horizontal, and 48° vertical.

Q: How much distortion does this M5 lens have?
A: The specified distortion is less than 1.5%, making low distortion one of the key characteristics of this lens.

Q: What sensor format is this lens designed for?
A: The lens is specified for a 1/5″ image format.

Q: What type of mount does this miniature lens use?
A: It uses an M5×0.35 miniature mount, which is suitable for highly compact camera modules.

Q: Is this lens a fisheye lens?
A: No. Although the 2.2mm focal length provides broad coverage, the 80° diagonal FOV and less-than-1.5% distortion are more consistent with a controlled wide-angle miniature design rather than an extreme fisheye configuration.

Q: Does the lens include an IR cut filter?
A: Yes. The lens construction is specified as 3P + IR cut filter. The IR cut filter does not mean the lens is an IR-corrected optical design.

Q: What is the minimum object distance?
A: The specified M.O.D. is 0.1m.
