Inline systems and offline equipment for both production control and development of OLED layers and stacks.
Experience and Knowledge
NXT has developed a product group to check both inline and offline all types of layers which are currently used for any type of OLED stack, including organic and inorganic layers.
Based on 15 years experience in thin-film testing, special optical components have been designed to guarantee highest precision of the spectral reflectance/transmittance which are needed for precise, reliable and fast testing of layer thickness and n&k.
