6.1mm M9 Low Distortion Lens Applications

Core Application Scenes

The 6.1mm focal length provides a more controlled field of view than short wide-angle lenses, making this lens suitable for imaging a defined inspection area without introducing excessive perspective coverage. Its low-distortion optical performance is particularly useful where consistent object geometry is important.

Designed for compact machine vision application.

Typical applications include:

• Machine Vision Inspection: Suitable for component inspection, dimensional checking, positioning, and visual quality control where low distortion is beneficial.
• Embedded Vision: The compact M9 mount makes the lens suitable for integrated camera modules installed inside industrial equipment.
• Robotics Vision: The controlled 50° horizontal FOV can provide focused scene coverage for robotic inspection and object positioning.
• Industrial Equipment Monitoring: Suitable for monitoring a defined area of machinery, instruments, or production equipment.
• AI Vision Systems: The 5MP optical specification supports image acquisition for recognition and classification systems.
• Compact OEM Cameras: The M9 × 0.35 interface is suitable for OEM imaging devices where installation space is limited.

For sensor and optical matching, the Sensor Guide can help verify the relationship between sensor format and lens coverage.

If the required working area and working distance are known, the FOV Calculator can be used to estimate whether the 6.1mm focal length provides the required image coverage.

Low Distortion Optical Performance

For machine vision applications, excessive lens distortion can alter the apparent shape and position of objects toward the image edges. This 6.1mm lens specifies less than 1% TV distortion, making it suitable for applications where consistent geometric representation is important.

The 60° diagonal FOV provides useful scene coverage while remaining more controlled than an ultra-wide-angle optical design. This balance can be advantageous for inspection systems that need to capture a defined working area rather than an extremely broad scene.

For applications involving measurement, alignment, or geometric inspection, the Distortion Guide provides additional information about distortion and its effect on machine vision imaging.

Compact M9 Optical Design

The M9 × 0.35 mount is suited to compact camera assemblies where conventional larger lens mounts may not fit. The 3.0mm B.F.L. further supports integration into small imaging modules.

The 2G2P + IRCF construction combines glass and plastic optical elements with an infrared cut filter configuration for visible-light imaging applications. The fixed F3.0 aperture provides a consistent optical setup for controlled industrial environments.

Frequently Asked Questions

Q: What sensor size is this 6.1mm lens designed for?
A: The specified optical performance is based on a 1/2.5″ image format, with a 60° diagonal, 50° horizontal, and 38° vertical field of view.

Q: Is this lens a wide-angle or fisheye lens?
A: No. The 6.1mm focal length and 60° diagonal FOV provide a moderate field of view rather than an ultra-wide or fisheye perspective. The lens is better classified as a low-distortion fixed focal lens.

Q: What is the distortion specification?
A: The specified TV distortion is less than 1%, which is suitable for applications where controlled geometric imaging is required.

Q: What is the resolution of this M9 lens?
A: The lens is specified for 5MP resolution and can be used with compatible 1/2.5″ camera sensors.

Q: What is the minimum object distance?
A: The M.O.D. is 0.2m, allowing the lens to be used for relatively close-range industrial imaging applications.

Q: What does the F3.0 aperture provide?
A: F3.0 provides a fixed optical aperture suitable for controlled machine vision and industrial imaging environments. Actual exposure performance also depends on sensor sensitivity and illumination.

Q: What cameras can use this M9 lens?
A: The M9 × 0.35 mount is suitable for compact industrial cameras, embedded vision modules, robotic imaging systems, OEM camera modules, and other compatible camera assemblies.

Q: How do I select the correct focal length for my application?
A: The required focal length depends on sensor size, working distance, and target field of view. The Focal Length Calculator can help estimate the appropriate focal length for a specific imaging setup.
