Fisheye Lens – S00914014528F

S00914014528F is 0.9mm High-Precision Fisheye lens with Built-In Filter, F2.8 170° M12/S-mount ultra-wide-angle lens,1/4″ Megapixel CCTV Lens.

0.9mm M12 170° Fisheye Lens

This 0.9mm M12 Fisheye lens is an fixed focal lens designed for compact 1/4″ imaging systems that require exceptionally broad scene coverage. It provides a 170° diagonal, 145° horizontal, and 122° vertical field of view, allowing a large surrounding area to be captured from a compact camera position. With an F2.8 fixed aperture, 0.1m M.O.D., 12mm T.T.L., and M12x0.5 mount, the lens is well suited to embedded and industrial imaging applications where wide coverage and compact optical integration are priorities.

M12 170° Fisheye Lens Core Product Highlights

• 170° diagonal FOV enables extremely broad scene coverage from a very short 0.9mm focal length.
• 145° horizontal and 122° vertical FOV provide extensive coverage for compact imaging systems.
• 0.9mm ultra-short focal length is suitable for applications requiring a very wide viewing angle.
• M12x0.5 mount and 12mm T.T.L. support compact camera and embedded imaging integration.
• 0.1m M.O.D. allows close-range wide-area imaging.
• F2.8 fixed aperture provides a simple optical configuration for compact camera modules.

Applications & Compatible Devices

Core Application Scenes

The extremely short 0.9mm focal length and 170° diagonal FOV make this lens particularly suitable when a conventional Fisheye lens cannot provide sufficient scene coverage.

Typical application scenarios include:

• Ultra-wide embedded vision systems
• Compact industrial monitoring cameras
• Wide-area machine vision
• Close-range scene monitoring
• Robotics and spatial awareness systems
• Compact inspection modules
• Indoor wide-area imaging
• Embedded camera and sensing modules
• Applications requiring broad peripheral scene coverage

Designed for ultra-wide embedded vision applications where maximum scene coverage and compact optical integration are more important than minimizing geometric distortion.

For additional compact M12 configurations, see TOWIN’s M12 Lenses. Engineers looking for other broad-coverage configurations can also review the M12 Wide Angle Lens category.

Compatible Devices

The lens is specified for a 1/4″ image format and can be evaluated for compact camera systems using compatible imaging sensors.

Potential device configurations include:

• 1/4″ compact camera modules
• Embedded industrial cameras
• Wide-angle vision modules
• Robotic vision devices
• Compact monitoring systems
• Machine vision imaging modules
• Space-constrained sensing equipment

Because the supplied specification lists the resolution as MP, the final camera pairing should be verified against the actual sensor resolution and image quality requirements before production integration.

TOWIN’s Sensor Guide provides additional guidance on matching image sensors and lenses.

Ultra-Wide Field of View

The main optical characteristic of this lens is its exceptionally broad field of view:

• 170° diagonal
• 145° horizontal
• 122° vertical

This makes the lens suitable for systems that need to observe a large surrounding area while keeping the optical assembly extremely compact.

The <-19% TV distortion should be considered during system design. This lens is not intended as a low-distortion optic. Instead, its design prioritizes extremely wide scene coverage. Applications involving precise dimensional measurement or strict geometric accuracy may require distortion correction or a different optical configuration.

For more information about the relationship between lens distortion and imaging performance, see TOWIN’s Distortion Guide.

The FOV Calculator can also help engineers evaluate whether this ultra-wide field of view is appropriate for a particular camera installation.

Compact M12 Optical Integration

The M12x0.5 mount makes the lens suitable for compact camera architectures where installation space is limited. Its 12mm T.T.L. further supports applications requiring a short overall optical package.

The 0.1m M.O.D. allows the lens to capture a wide scene even when the camera is installed relatively close to the target area. This characteristic can be valuable for compact embedded devices where both camera size and viewing coverage are important design constraints.

For applications involving customized optical and mechanical integration, TOWIN’s Optical Design resources provide additional technical guidance.

Fisheye vs. Low-Distortion Selection

This 0.9mm lens should be selected when maximum viewing coverage is the primary optical requirement.

It is different from a low-distortion lens such as a conventional machine vision optic. The <-19% TV distortion specification means some image deformation is expected, particularly toward the edges of the very wide image.

For applications such as scene awareness, broad-area monitoring, object detection, and embedded vision, this trade-off can be acceptable. For precision inspection or measurement, engineers should evaluate distortion together with sensor characteristics, working distance, calibration, and image-processing requirements.

TOWIN’s Lens Selection Guide can help compare focal length, FOV, distortion, sensor format, and application requirements.

Why Choose This 0.9mm M12 Fisheye Lens?

This lens combines an extremely short 0.9mm focal length, 170° diagonal FOV, 145° horizontal FOV, 122° vertical FOV, 0.1m M.O.D., and 12mm T.T.L. in a compact M12 optical configuration.

Its primary advantage is the ability to capture an exceptionally large area from a small camera installation. This makes it particularly valuable for embedded imaging systems where the available optical space is limited but the required viewing area is large.
