Abstract

An illuminator system for semiconductor chip testing has a rotary plate and a first light source and second light source mounted on the rotary plate. A controller is configured to rotate the rotary plate to provide a desired light output. A light output of the illuminator system is aligned to the desired first or second light source. A first semiconductor chip receives illumination from the desired source. The rotary plate is rotated until the desired light source is aligned to the light output. A quality or characteristic of light emitted by the first light source can be measured, and then the first light source can be adjusted, or an alert can be generated, if the quality or characteristic falls outside of a preconfigured range.
