  3. How to Choose Industrial Lenses in Machine Vision Solutions?

In a machine vision project, industrial lens is one of the important components, so when determining a machine vision solution, how should we choose industrial lens?

1、Clarify the lens field of view, optical magnification and working distance required in the customer’s machine vision solution

When selecting an industrial lens, a lens with a slightly larger field of view than the object under test is usually selected to facilitate motion control.

2、Depth of field requirements:

For the requirement of depth of field, the aperture should be as small as possible; for the choice of magnification, use low-magnification industrial lens as far as possible under the project permit. If the project requirements are more stringent, I tend to choose a sophisticated industrial lens with a high depth of field.

3、Camera chip size and camera interface:

Each lens has matching camera interface and chip size specifications. For example, a 2/3″ industrial lens supports the largest industrial camera rake surface of 2/3″, which cannot support industrial cameras above 1″.

4、Pay attention to the coordination with the light source, and choose a suitable industrial lens

Lenses of different specifications also have matching light sources to choose from.

5、Customer’s installation environment:
In the case of alternative solutions, it is unrealistic for customers to change the size of the equipment. Lenses with similar optical parameters and different sizes can be selected according to their needs.
