Industrial Lens Knowledge Center

An industrial lens is an optical lens designed for machine vision, automation, AI imaging, and industrial inspection applications requiring high precision and imaging stability.

Choosing the right machine vision lens depends on sensor size, focal length, working distance, field of view, distortion requirements, and lighting conditions. A properly matched lens improves image clarity, inspection accuracy, and overall system performance.

Field of view (FOV) refers to the visible area captured by a camera and lens system. In machine vision applications, the correct field of view ensures that the target object is fully captured with the required level of detail and measurement accuracy.

Optical distortion is caused by the curvature and design of lens elements, which can make straight lines appear curved in an image. Common types include barrel distortion and pincushion distortion. Low distortion lenses help improve imaging precision in industrial vision systems.

The ideal sensor size depends on your application requirements, including resolution, field of view, working distance, and lighting conditions. Larger sensors generally provide higher image quality and wider coverage, while smaller sensors are suitable for compact imaging systems.

M12 lenses are compact and lightweight lenses commonly used in embedded vision and small camera systems, while C-Mount lenses are larger industrial lenses designed for higher imaging performance, larger sensors, and more demanding machine vision applications.

MTF (Modulation Transfer Function) is a key optical performance indicator used to evaluate how well an industrial lens can reproduce image details and contrast. A higher MTF value means the lens can capture finer details with better sharpness and resolution, making it especially important for applications such as machine vision inspection, precision measurement, and high-resolution imaging systems.

Sensor size directly affects image coverage, field of view, and lens compatibility in an industrial imaging system. A larger sensor requires a lens with a larger image circle to avoid vignetting, while a smaller sensor may provide a narrower field of view with the same focal length. Choosing the correct sensor and lens combination ensures optimal image quality, resolution, and system performance.
