M12 Wide Angle Lens Applications

Core Application Scenes

This 2.8mm M12 Wide Angle lens is developed for compact imaging systems where a broad viewing angle and strong low-light capability are important. Its 136° diagonal field of view on a 1/2.7″ sensor allows a camera to cover a large area from a relatively short installation distance, reducing the need for multiple narrow-angle cameras in certain monitoring configurations.

The F1.0 aperture is a key advantage for indoor environments, evening monitoring, and other scenes where available light is limited. Combined with 5MP resolution, the lens provides a balance between broad coverage and image detail for embedded camera platforms.

For robotics and intelligent vision devices, the ultra-wide perspective can provide greater environmental visibility around the camera. It is suitable for compact mobile robots, service robots, smart devices, and embedded AI vision modules where optical space is restricted but a large viewing area is required.

The integrated filter structure also makes this model suitable for camera modules that require a protected optical configuration. Depending on the final camera design and filter specification, it can be incorporated into customized embedded imaging assemblies.

When selecting an M12 lens for a particular sensor, the sensor size and active image area should be checked together with the required field of view. The Sensor Guide provides additional information for matching lenses with image sensors.

For applications where field coverage needs to be calculated before selecting a lens, the FOV Calculator can help evaluate focal length, sensor format, and viewing requirements.

For applications requiring controlled geometric accuracy rather than extreme Wide Angle coverage, compare this design with the Low Distortion Lens range.

Designed for low-light wide-area monitoring, embedded AI vision, robotics imaging, and compact camera applications.

Frequently Asked Questions

Q: What type of lens is this 2.8mm M12 lens?
A: It is a fixed focal length M12 Wide Angle lens designed for ultra-wide-angle imaging. Its 136° diagonal FOV on a 1/2.7″ sensor supports broad scene coverage.

Q: What is the field of view of the 2.8mm lens?
A: On a 1/2.7″ sensor, the specified FOV is 136° diagonal, 110° horizontal, and 57° vertical. On a 1/2.8″ sensor, it is 134° diagonal, 98° horizontal, and 71° vertical.

Q: Why is the distortion specified as less than -59%?
A: High negative distortion is inherent to this wide-angle design, enabling an extremely wide FOV at a compact 2.8mm focal length.

Q: What is the main advantage of the F1.0 aperture?
A: F1.0 is an ultra-fast aperture delivering high light throughput to the image sensor, ideal for indoor, dusk and other low-light imaging scenarios.

Q: Which image sensors are compatible with this lens?
A: The lens is specified for 1/2.7″ and 1/2.8″ image formats. Final compatibility should be verified against the sensor’s active image area and the required camera image quality.

Q: Is this lens suitable for CCTV applications?
A: Integratable into compact surveillance camera modules for ultra-wide viewing angles. Its wide-angle design excels at broad-area situational monitoring, not precision surveillance of distant targets.

Q: What does “With filter” mean in the lens structure specification?
A: Optical structure supports filter configuration. Exact filter type and spectral performance to be confirmed against camera module and application requirements.

Q: Can Towin customize this 2.8mm M12 lens?
A: Towin can evaluate customized optical and mechanical requirements based on the sensor, FOV, housing dimensions, filter requirements, and application environment. Project-specific requirements can be submitted through the Contact Towin page.
