M12 Fisheye Lens Applications

Core Application Scenes

This 2.3mm M12 fisheye lens is designed for applications where maximizing scene coverage is more important than maintaining low geometric distortion. Its 170° diagonal FOV on a 1/2.7″ sensor allows a compact camera module to capture a very broad area, making it useful for panoramic and situational-awareness imaging.

For embedded vision systems, the compact M12 lens format makes this model suitable for small camera housings where a conventional wide-angle lens may not provide sufficient coverage. It can be integrated into compact monitoring cameras, robotic vision modules, smart IoT devices, and embedded AI cameras.

In robotics, the ultra-wide perspective can help provide a broader visual view for navigation and environmental awareness. The lens can also be considered for compact indoor surveillance systems, where a single camera needs to monitor a large area from a relatively fixed installation point.

The F1.6 aperture provides useful light-gathering capability for indoor and moderately low-light environments, while the fixed 2.3mm focal length provides a simple optical configuration without the mechanical complexity of a zoom mechanism.

Frequently Asked Questions

Q: What type of lens is the 2.3mm M12 lens?
A: It is a fixed focal length M12 fisheye lens with an ultra-wide field of view. On a 1/2.7″ sensor, it provides a 170° diagonal FOV.

Q: What sensors are compatible with this M12 fisheye lens?
A: The lens is specified for 1/2.7″ and 1/3.2″ image formats. The actual camera design should also verify the sensor’s active image area and optical interface.

Q: What is the field of view of this 2.3mm lens?
A: On a 1/2.7″ sensor, the FOV is 170° diagonal, 141° horizontal, and 80° vertical. On a 1/3.2″ sensor, it is 136° diagonal, 109° horizontal, and 82° vertical.

Q: Why does this lens have such high negative distortion?
A: This fisheye ultra-wide lens uses intentional negative distortion to achieve an expansive FOV in a compact optical layout, not rectilinear low-distortion imaging.

Q: Is this lens suitable for machine vision inspection?
A: Suitable for machine vision systems requiring wide scene coverage and situational awareness. Low-distortion machine vision lenses are recommended for precision measurement and dimensional inspection.

Q: What is the advantage of the F1.6 aperture?
A: The F1.6 aperture provides relatively strong light-gathering capability, which can help maintain usable image brightness in indoor environments and other scenes with limited illumination.

Q: What does M12X0.5 mean?
A: M12X0.5 indicates the mechanical lens thread: a 12mm diameter mount with a 0.5mm thread pitch. It is commonly used for compact camera modules and embedded vision systems.

Q: Can Towin customize this M12 fisheye lens?
A: Towin can evaluate optical and mechanical customization requirements based on the camera module, sensor, housing dimensions, FOV, and application requirements. For a project-specific configuration, contact the Towin optical engineering team with your requirements.
