Five Points to Note When Choosing a Machine Vision Light Source

Selecting the right light source is crucial in machine vision inspection. As the saying goes, choosing the right light source is half the success of the project. So when starting a new project, the most challenging task is selecting the appropriate light source. Let's examine "Five Points to Note When Choosing a Machine Vision Light Source" with falenses technology.

1. Contrast

The primary purpose of lighting the object being inspected is to enhance the contrast between defects and the background, making defects more visible for further processing by machine vision algorithms. This is one of the most critical factors when choosing a light source.

2. Uniformity

Uneven illumination can create many problems in later image processing, even rendering the captured images useless. For example, reflective parts can cause specular reflections, resulting in bright spots on the surface. If a defect is covered by a bright spot, it can lead to missed or incorrect detections.

3. Brightness

If the brightness is too high, defects might be obscured; if too low, the contrast might be insufficient, diminishing the purpose of lighting. Therefore, choosing the appropriate brightness level is essential.

4. Stability

Stability refers to the light source's ability to maintain consistent illumination over a certain period.

5. Cost and Lifespan

A high price doesn't necessarily mean the most suitable, nor does it guarantee it is affordable. The longer the lifespan of a light source, the better—it not only reduces costs but also minimizes system adjustments due to light source replacement.
