1.0mm Megapixel M12 189° Ultra Wide Angle Fisheye Lens

The TOWIN 1.0mm M12 ultra wide angle Fisheye lens provides an exceptionally broad 189° diagonal FOV on a 1/4″ image format, making it suitable for compact vision systems that require maximum scene coverage from a very short working distance. With an F2.0 aperture, M12X0.5 mount, 0.2m M.O.D., and compact optical construction, this fixed focal lens is designed for embedded machine vision and other space-constrained imaging applications.

M12 189° Fisheye Lens Core Product Highlights

• 1.0mm ultra-short focal length for extremely wide scene coverage.
• 189° diagonal FOV on a 1/4″ image format, with 160° horizontal and 95° vertical FOV.
• F2.0 aperture provides a relatively fast optical configuration for compact imaging systems.
• M12X0.5 mount supports integration into small embedded camera modules.
• 0.2m M.O.D. enables wide-area imaging from relatively close working distances.
• Fixed focal and fixed iris design provides a compact configuration for dedicated vision systems.

M12 189° Fisheye Lens Applications

Core Application Scenes

The combination of a 1.0mm focal length and 189° diagonal FOV makes this lens particularly suitable when broad spatial coverage is more important than maintaining rectilinear image geometry. The substantial optical distortion of <-37% should be considered when selecting the lens for applications that require accurate dimensional measurement or geometric reconstruction.

Typical application scenarios include:

• Compact embedded vision systems requiring an exceptionally wide field of view
• Wide-area scene monitoring with space-constrained camera installation
• Short-distance object and environment detection
• Robotics vision requiring broad environmental awareness
• Compact smart-camera modules
• Panoramic or near-panoramic imaging configurations
• Machine vision systems where a single camera needs to cover a large surrounding area

For applications requiring controlled geometric accuracy, users should compare this lens with TOWIN Low Distortion Lens products rather than selecting an ultra-wide fisheye configuration solely based on FOV.

Designed for ultra-wide-angle embedded vision applications where maximum scene coverage is a primary optical requirement.

Compatible Devices

This lens can be considered for compact imaging devices using:

• 1/4″ image-format sensors where the specified FOV is applicable
• M12X0.5 threaded camera modules
• Embedded machine vision cameras
• Compact robotics vision modules
• Small-form-factor smart cameras
• Wide-area monitoring camera modules
• Vision devices operating at close working distances

For sensor and image-format matching, refer to the TOWIN Sensor Guide before final lens selection. The available image circle and sensor dimensions should be checked together with the required FOV.

Optical Design Considerations

A 1.0mm focal length combined with a 189° diagonal FOV places this lens firmly in the ultra-wide/fisheye category. The <-37% TV distortion is therefore an important characteristic of the optical design rather than a specification that should be interpreted as low distortion.

When integrating this lens into a vision system, the required scene coverage, sensor size, camera position, working distance, and acceptable image distortion should all be evaluated together.

For applications where the primary objective is to capture the largest possible area with a compact camera, this type of ultra-wide optical configuration can reduce the number of cameras required in some system designs. For applications requiring straight-line preservation or precise measurement, a lower-distortion lens should be considered instead. TOWIN’s Distortion Guide provides additional information for evaluating these optical requirements.

The FOV Calculator can also be used during system planning to compare focal length, sensor format, and required field of view.

Why Choose a 1.0mm M12 189° Fisheye Lens?

The key advantage of this lens is its ability to combine an extremely short 1.0mm focal length with a very large field of view in a compact M12 configuration. The 189° diagonal FOV can be valuable when the camera has limited installation space or when the system must observe a large surrounding area from a relatively close position.

Its F2.0 aperture, 0.2m M.O.D., and 3.49mm B.F.L. further define the optical configuration for compact camera integration.

For engineers selecting between different focal lengths and optical architectures, TOWIN’s Lens Selection Guide can help evaluate focal length, sensor compatibility, FOV, distortion, and mechanical requirements together.
