Illumination

Illuminate features & make defects visible

Selecting the perfect lighting

And it's worth it!

The importance of correct lighting in machine vision

Proper lighting is an essential element in machine vision. It forms the basis for accurate and reliable inspections and plays a key role in the detection and analysis of faults and defects. Carefully selected lighting ensures uniform and optimal illumination of the inspection object, which significantly improves image quality and increases the accuracy of processing.

Without the right lighting, even the best cameras and image processing algorithms cannot deliver the best results.

1. Field of view and inspected object

What is the size of the field of view and the object to be inspected?

2. Working distances

How far is the camera and lighting from the object?

3. Lighting type and intensity

What lighting types and light intensity is required for illumination?

4. Component features

How do the inspection features look like and with which lighting technique can they be detected?

5. Macroscopic and microscopic shape properties

Which material properties and surface characteristics does the object have?

6. Colour

Which colour does the part have?

7. Wavelength of light

Which light colour is required? White, Red, Blue, Green? IR or UV radiation?

Any type of lamp can be used for lighting, as long as it does the job and fits into the system.

Today, however, LED lighting is the most common. They all have individual characteristics that make them more or less suitable for use.

Conclusion:

Choosing the right lighting depends on a variety of physical factors that are often difficult to predict. Trial and error is explicitly allowed and is the basis for a stable application.
