1.8mm M12 Ultra Wide Angle Lens Applications

Core Application Scenes

The extremely short 1.8mm focal length and 140° horizontal FOV make this lens suitable for applications where maximizing scene coverage is more important than maintaining low geometric distortion.

Typical applications include:

• Automotive surround and auxiliary vision: The ultra-wide FOV can capture a broad area around a vehicle or equipment platform.
• Vehicle-mounted monitoring: The 140° horizontal field of view helps reduce blind areas in close-range monitoring scenarios.
• Outdoor security and monitoring: IP67 protection supports camera installations exposed to dust and water.
• Wide-area scene monitoring: The lens can capture a large visual area using a single compact camera module.
• Embedded AI vision: The broad FOV can provide extensive scene information for object detection and environmental perception.
• Compact camera systems: The 13.35mm T.T.L. is useful where the available optical installation space is limited.
• Near-field monitoring: The ultra-wide optical configuration is suitable for applications requiring coverage of objects or areas close to the camera.

Designed for automotive wide-angle vision, outdoor monitoring, embedded AI imaging, and near-field wide-area applications.

Compatible Device List

• 1/2.9-inch GC2093 camera modules — directly matched to the specified 2MP sensor format.
• Automotive camera modules — IP67 protection supports vehicle-mounted applications.
• Wide-angle embedded cameras — 1.8mm focal length provides extensive scene coverage.
• Outdoor monitoring cameras — IP67 construction supports exposed installation environments.
• AI vision camera modules — broad image coverage provides extensive visual information for perception algorithms.
• Compact M12 camera systems — M12x0.5 mounting and short T.T.L. simplify mechanical integration.

Ultra Wide Angle Optical Performance

The 1.8mm focal length produces an extremely broad field of view, reaching 154° diagonal, 140° horizontal, and 89° vertical with the GC2093 sensor.

This optical configuration is particularly useful when the camera needs to observe a large surrounding area from a relatively close installation position. Compared with longer focal-length lenses, the 1.8mm design significantly expands scene coverage.

The trade-off is the specified TV distortion below -19%. Therefore, this model should be selected when broad coverage is a higher priority than maintaining extremely low geometric distortion.

For applications that require lower distortion and more accurate image geometry, TOWIN also provides dedicated Low Distortion Lenses.

Compact Mechanical Design

With a 13.35mm T.T.L., the lens is suitable for compact camera housings and embedded vision modules where installation space is limited.

The M12x0.5 mount provides a commonly used mechanical interface for miniature camera systems, while the manual focus configuration allows installers or system integrators to adjust focus according to the actual working distance.

The CRA below 25° also supports compatibility considerations when integrating the lens with the selected image sensor.

Environmental Protection

The lens features an IP67 waterproof rating, making it suitable for applications where the optical assembly may encounter dust, rain, splashing water, or other outdoor environmental conditions.

Potential environments include:

• Automotive camera systems
• Outdoor monitoring equipment
• Industrial equipment
• Embedded vision devices
• Smart transportation systems
• Vehicle-mounted cameras

For the final system, the complete camera enclosure and mechanical assembly should also be evaluated because the system-level environmental protection depends on more than the lens alone.

Frequently Asked Questions
