1.7mm M12 Wide Angle Lens with 157° Ultra-Wide FOV

This 1.7mm M12 Wide Angle lens is designed for compact cameras requiring an exceptionally wide field of view in a small optical package. With a 157° diagonal FOV, F1.2 aperture, M12×0.5 mount, and visible + 940nm pass filter, it is suitable for wide-area monitoring, compact security cameras, and specialized imaging systems requiring broad scene coverage.

Product Highlights at a Glance

• 157° diagonal FOV provides extremely wide scene coverage for compact camera systems.
• 1.7mm focal length enables broad-area imaging where conventional lenses cannot provide sufficient coverage.
• F1.2 aperture provides a bright optical configuration for compact imaging applications.
• M12×0.5 mount and 1.2mm B.F.L. support integration into space-constrained camera modules.
• Visible + 940nm pass filter enables specialized spectral filtering for camera applications requiring this optical configuration.

1.7mm M12 Wide Angle Lens Applications

This M12 Wide Angle lens is designed for applications where maximizing scene coverage is more important than maintaining low geometric distortion. Its 157° diagonal field of view and 1.7mm focal length allow compact cameras to capture a very broad area from a fixed installation position.

The significant negative distortion is characteristic of the Wide Angle optical configuration and should be considered when the application requires geometric measurement or accurate straight-line reproduction.

Core Application Scenes

• Wide-area security monitoring — Suitable for compact cameras that need to monitor a broad indoor or localized area from a fixed position.
• Panoramic-style imaging — The ultra-wide FOV can capture a large portion of the surrounding scene with a single camera.
• Compact embedded cameras — The M12×0.5 interface and short B.F.L. make the lens suitable for space-constrained camera assemblies.
• Situational awareness cameras — Useful where broad environmental visibility is more important than conventional rectilinear image geometry.
• Specialized visible and near-infrared imaging — The visible + 940nm pass-filter configuration supports camera designs requiring this specific spectral transmission setup.
• OEM camera modules — Suitable for customized compact imaging products requiring an ultra-wide optical configuration.

Designed for ultra-wide-area monitoring and specialized compact imaging applications, this lens combines a 157° diagonal FOV with a compact M12 optical interface.

Frequently Asked Questions

Q: Is this lens a Wide Angle lens?
A: Yes. The combination of a 1.7mm focal length, 157° diagonal FOV, and < -59% distortion clearly places this product in the Wide Angle lens category.

Q: What is the maximum field of view of this lens?
A: With the specified KW33000A1T configuration, the lens provides a 157° diagonal FOV, 124° horizontal FOV, and 92° vertical FOV.

Q: What camera format is this lens designed for?
A: The specification lists a maximum image format of Φ4.9 and a 1/4″ camera format, with VGA resolution.

Q: Does the lens provide low-distortion imaging?
A: No. The specified distortion is < -59%, which is characteristic of the ultra-wide fisheye configuration. It should not be classified as a low distortion lens.

Q: What is the purpose of the 940nm pass filter?
A: The integrated visible + 940nm pass filter provides a specified spectral transmission configuration for camera systems designed to work with visible and near-infrared illumination around 940nm.

Q: Is this an IR corrected lens?
A: The supplied specification does not state IR correction performance. The presence of a 940nm pass filter should therefore not be interpreted as proof that the lens is an IR corrected lens.

Q: Can the focus be adjusted?
A: Yes. The lens uses manual focus, allowing the optical focus position to be adjusted during camera assembly or installation.

Q: Does this lens have optical zoom?
A: No. It has a fixed 1.7mm focal length and fixed zoom configuration.
