1.75mm M7 Fisheye Lens Applications

Core Application Scenes

This 1.75mm M7 fisheye lens is designed for applications where maximizing scene coverage is more important than maintaining low geometric distortion. Its 177° diagonal FOV allows a compact camera module to observe a very large area without requiring a conventional multi-camera arrangement.

For compact panoramic imaging, the lens can be integrated into embedded camera modules where installation space is limited but an extremely wide viewing angle is required. The 1.75mm focal length and M7×0.35 mount make it particularly suitable for miniature imaging equipment, smart embedded devices, and compact vision modules.

In robotics and mobile vision, the ultra-wide perspective can help provide broad environmental awareness around a compact camera installation. The lens can also be considered for panoramic monitoring, interactive devices, compact IoT cameras, and other systems where a wide field of view is a primary design requirement.

For engineers comparing focal length and viewing coverage, the FOV Calculator can help estimate the relationship between sensor format, focal length, and field of view.

Optical & Lens Selection Considerations

The extremely high negative distortion of this lens is an intentional characteristic of its fisheye optical design rather than a low-distortion imaging feature. With a 177° diagonal field of view, the lens prioritizes maximum scene coverage and compact optical implementation.

When selecting this type of lens, engineers should evaluate the sensor format, required field of view, installation distance, and acceptable image geometry together. Towin’s Lens Selection Guide provides additional guidance for matching lens specifications with different imaging requirements.

The 0.2m minimum object distance also makes this lens suitable for relatively close-range wide-area imaging, while the 3.46mm back focal length should be considered when designing the camera’s mechanical structure.

For applications requiring a different focal length or sensor combination, the M7/M6/Miniature Lens product range can be evaluated as part of the lens selection process.

Frequently Asked Questions
