2.8mm M8 Low Distortion Lens Applications

Core Application Scenes

This 2.8mm M8 wide angle lens is designed for compact camera systems where a large viewing area is required from a short physical installation distance. Its 102° diagonal FOV on a 1/2.6″ sensor allows one camera to cover a relatively broad scene, making it suitable for embedded vision devices, compact monitoring modules, and wide-area imaging equipment.

The lens is particularly useful when camera installation space is limited but the system still needs to observe a large area. The M8 × 0.35 mount and 14.19mm T.T.L. help keep the optical assembly compact, while the <0.2% TV distortion specification helps reduce the geometric deformation commonly associated with wide-angle imaging.

In equipment where the camera must observe a broad working area rather than a small inspection target, this lens can provide a practical alternative to longer focal-length optics. Its 2.8mm fixed focal length also provides a consistent FOV once the camera position has been established.

For engineers matching the lens to a particular camera sensor, the Sensor Guide can be used to evaluate image format compatibility and sensor-related optical considerations.

Compatible Device List

• Embedded Vision Cameras: Suitable for compact camera modules requiring a broad viewing angle within a small mechanical envelope.
• Industrial Monitoring Devices: The wide FOV can help cover larger work areas from a relatively short camera-to-scene distance.
• Compact Machine Vision Systems: Suitable for applications where scene coverage is more important than long-range magnification.
• Smart Security Camera Modules: The 2.8mm focal length can provide broad scene observation for compact camera assemblies.
• Robotics & Mobile Vision: Suitable for robotic or mobile imaging systems that need to observe a wider surrounding area.
• OEM Camera Modules: The M8 × 0.35 interface supports integration into customized embedded imaging equipment.

When determining whether the 2.8mm focal length provides sufficient coverage for a specific working distance, engineers can use the FOV Calculator to estimate the required field of view.

Designed for compact wide-area imaging and embedded machine vision applications.

Optical Performance & Design Considerations

The combination of 2.8mm focal length and up to 102° diagonal FOV makes this lens suitable for applications requiring broad scene coverage. On a 1/2.6″ sensor, the specified FOV is 102° diagonal, 92° horizontal, and 66° vertical. On a 1/2.7″ sensor, the diagonal FOV is 100°, with 92° horizontal and 59° vertical coverage.

Despite its wide field of view, the lens specifies TV distortion below -0.2%. This characteristic is useful when the application needs a wide viewing area while still requiring relatively controlled image geometry.

The 0.2m M.O.D. provides flexibility for relatively close-range scene observation, while the F2.4 aperture provides a practical optical configuration for compact camera modules.

For applications where distortion is an important selection factor, the Distortion Guide provides additional information about how lens distortion affects imaging geometry.

Engineers developing compact optical modules can also review the M8/M7/M6/M5/M3.5 Small Mount Lenses category for alternative miniature mounting configurations.
