| Ambient light refers to any outside light such as sunlight coming through windows or overhead room light. |
|
It seldom lends itself to suitable illumination for vision applications, as it tends to be inconsistent and causes inaccurate inspection results.
It is therefore critical to control any and all ambient light within the immediate area of the vision installation.
Sometimes this means building a shroud over or around the area of installation to completely block all ambient light.
In other cases this could mean flooding the inspection area with enough dedicated stable light so as to supersede any ambient light. |
