Depth of Field, the key to obtain sharp images

Have you ever wondered why some photographs have a beautifully blurred background while others keep everything sharply in focus?

This phenomenon is known as depth of field, and it plays a crucial role in the world of machine vision. Depth of field refers to the maximum range of distance an object appears to be in acceptable focus. In machine vision applications, achieving the correct depth of field is essential for accurately measuring and analyzing images.

By adjusting parameters such as aperture size, focal length, and working distance, you can modify the depth of field to suit specific inspection requirements. For example, a shallow depth of field is ideal for highlighting specific features or defects on objects, while a larger depth of field ensures that an entire object will remain in focus.

In manufacturing industries like automotive, pharmaceutical and semiconductor, precise DoF is critical to their machine vision systems. Liquid lens solutions can help you meet the DoF requirements for a given vision task. They can provide added flexibility, enhance quality inspection processes, improve efficiency and ensure product consistency.
