OLEDs are rapidly moving from the research lab to the fab. Their bright, ultra-thin, and dynamic characteristics make them appealing for many display applications, ranging from cell phones to TVs. The metrology of the many thin films that make up such displays is of critical importance. Our spectroscopic instruments offer inexpensive, robust, and non-invasive metrology of simple prototype devices and fully-pixelated displays. Because our instruments are spectroscopic, one can also detect chemical changes that can occur in these atmospherically-sensitive materials.
