M12 200° Fisheye Lens Applications

Core Application Scenes

The defining characteristic of this lens is its extremely wide field of view. With a maximum specified diagonal FOV of 200°, it is designed for applications where maximizing scene coverage is more important than maintaining conventional rectilinear image geometry.

The lens is suitable for applications such as:

• Ultra-wide embedded vision
• Panoramic imaging systems
• Wide-area object detection
• Compact monitoring modules
• Robotics perception
• Embedded vision cameras
• Surround-view imaging concepts
• Short-distance wide-area imaging
• Space-constrained optical modules

Because the specified optical distortion is <-122%, this lens should not be treated as a conventional low-distortion wide-angle lens. The strong optical projection is an important part of achieving its exceptionally wide field of view.

Designed for ultra-wide-angle and fisheye imaging applications where maximum scene coverage is the primary optical requirement.

Compatible Devices

The M12x0.5 mount makes this lens suitable for compact camera assemblies where a small mechanical interface is required.

Potential compatible devices include:

• M12 camera modules
• Embedded vision cameras
• Compact industrial cameras
• Miniature robotic vision modules
• Wide-area monitoring cameras
• OEM imaging modules
• Compact panoramic camera systems
• Space-constrained embedded cameras

The specified image format is Φ4.7mm, so the optical image coverage and sensor active area should be checked carefully before integration.

TOWIN’s Sensor Guide can help engineers evaluate sensor and lens compatibility during the camera design process.

200° Ultra-Wide Field of View

The most important feature of this lens is its extremely broad viewing angle.

The specified FOV values are:

• 200° at 4.7mm
• 185° at 4.6mm
• 136° at 3.84mm
• 110° at 3.4mm

These values demonstrate how the lens is designed to capture a very large angular range within a compact imaging system.

This makes the lens particularly useful when the camera cannot be positioned far enough from the target to achieve broad scene coverage with a conventional lens.

Engineers should distinguish between fisheye FOV and rectilinear FOV when evaluating system performance. A fisheye optical design intentionally uses a different image projection to achieve much wider angular coverage.

For general field-of-view planning, TOWIN’s FOV Calculator can be used as part of the lens selection process.

Fisheye Projection and Distortion

The specified optical distortion of <-122% is a fundamental characteristic of this ultra-wide-angle design rather than a defect that should be compared directly with low-distortion machine vision lenses.

For applications such as panoramic perception, wide-area detection, and environmental awareness, the ability to capture a very large angular range can be more important than preserving straight-line geometry.

However, if the application requires accurate dimensional measurement or conventional geometric reconstruction, engineers should evaluate whether a lower-distortion optical design would be more appropriate.

TOWIN’s Distortion Guide provides additional information for comparing optical distortion characteristics.

Compact M12 Optical Integration

The M12x0.5 mount, 14mm T.T.L., and 3.46mm B.F.L. make the lens suitable for compact optical integration.

When integrating the lens into a camera housing, engineers should verify:

1. M12x0.5 mechanical compatibility
2. Sensor active area and image coverage
3. B.F.L. and sensor positioning
4. Housing clearance
5. Optical alignment
6. Image-processing requirements for fisheye distortion

For additional optical integration considerations, see TOWIN’s Optical Design resources.

Lens Selection Considerations

When selecting an ultra-wide-angle M12 lens, engineers should evaluate the entire optical system rather than focusing only on focal length.

Important parameters include:

• Image Format: Φ4.7mm
• Focal Length: 1.8mm
• Maximum FOV: 200°
• Resolution: 5 Megapixel
• Optical Distortion: <-122%
• Aperture: F2.0
• Minimum Object Distance: 0.1m
• Mount: M12x0.5
• T.T.L.: 14mm
• B.F.L.: 3.46mm

For this particular lens, the most important selection question is whether the application prioritizes maximum angular coverage or low geometric distortion.

If maximum scene coverage is the priority, the 200° FOV provides a major advantage. If image geometry and measurement accuracy are more important, engineers should instead evaluate TOWIN’s Low Distortion Lens options.

Frequently Asked Questions

Q1: What is the maximum field of view of this M12 fisheye lens?

A: The specified maximum field of view is 200° at an image height of 4.7mm. Additional specified FOV values are 185° at 4.6mm, 136° at 3.84mm, and 110° at 3.4mm.

Q2: Is this an ultra-wide-angle or fisheye lens?

A: It is best categorized as an ultra-wide-angle fisheye lens. The 200° maximum FOV and <-122% optical distortion are characteristic of a fisheye-type optical design.

Q3: Is this a low-distortion M12 lens?

A: No. The specified optical distortion is <-122%. This lens prioritizes extremely wide angular coverage rather than low geometric distortion.

Q4: What sensor or image format is this lens designed for?

A: The specified image format is Φ4.7mm. The camera sensor and active imaging area should be checked against this optical image coverage before integration.

Q5: What is the minimum object distance?

A: The specified M.O.D. is 0.1m, or 100mm, making the lens suitable for relatively close-range wide-area imaging.

Q6: What mount does this fisheye lens use?

A: The lens uses an M12x0.5 mount, making it suitable for compact M12 camera modules and embedded optical systems.

Q7: Is the 1.8mm M12 lens suitable for machine vision?

A: It can be suitable for machine vision applications that require extremely wide scene coverage, such as environmental perception, wide-area detection, and compact embedded vision. Applications requiring precision measurement should carefully evaluate the specified optical distortion.

Q8: What is the advantage of a 200° fisheye lens?

A: A 200° field of view allows the camera to capture an exceptionally large angular area from a single compact optical position. This can reduce blind spots in applications where broad environmental visibility is more important than conventional image geometry.
