Machine vision lenses are the cornerstone of modern industrial automation, enabling machines to “see” and interpret their surroundings with human-like precision. These specialized lenses transform raw visual data into actionable insights, driving efficiency in manufacturing, robotics, quality control, and beyond.
But not all machine vision lenses are created equal. Depending on the application, environment, and performance requirements, selecting the right lens type can mean the difference between flawless operation and costly errors.
Fixed focal length (FFL) lenses, also known as “prime lenses,” are the workhorses of machine vision. These lenses have a non-adjustable focal length, meaning their field of view (FOV) and magnification are fixed. This simplicity makes them highly reliable and cost-effective for applications where the object distance and size remain constant.
Key Advantages:
Common Applications:
Example: A fixed 12mm lens is perfect for inspecting small PCB components at a consistent working distance.

Zoom lenses offer adjustable focal lengths, allowing users to change the FOV and magnification without physically moving the camera or object. This flexibility makes them invaluable for applications requiring dynamic adjustments, such as multi-object inspection or variable working distances.
Key Advantages:
Common Applications:
Example: A 12–50mm zoom lens can inspect both tiny components and larger assemblies without swapping lenses.
Telecentric lenses are engineered to eliminate perspective distortion, ensuring that objects appear the same size regardless of their distance from the lens. This makes them indispensable for metrology and dimensional measurement applications where accuracy is non-negotiable.
Key Advantages:
Common Applications:
Example: A bilateral telecentric lens can measure the diameter of a cylindrical part with sub-pixel accuracy.Recommended Reading: M12 telecentric lenses for machine vision
Macro lenses specialize in capturing extreme close-up images with high magnification. These lenses are essential for inspecting minute details, such as surface textures, microchips, or pharmaceutical tablets.
Key Advantages:
Common Applications:
Example: A 10x macro lens can detect scratches on a smartphone screen that are just a few microns wide.

LiDAR (Light Detection and Ranging) lenses are designed for 3D sensing applications, such as autonomous vehicles, drones, and robotics. These lenses work in tandem with LiDAR sensors to create high-resolution depth maps of the environment.
Key Advantages:
Common Applications:
Example: A LiDAR lens with a 120° FOV helps a delivery robot avoid obstacles in real time.
