Hydration Monitoring with Cw-Terahertz Systems
Water provides a strong contrast in terahertz imaging Terahertz measurements can help to optimize irrigation strategies Cw-Terahertz systems
Terahertz Systems for Security Applications
Plastics, paper and cardboard are transparent in the THz range. Imaging with terahertz waves reveals hidden objects. Many explosives and illicit
Inspection for Process Optimization
Any production line of optical media requires inspection tools in order to maintain high quality standards. Shape and depth of structures have to meet strict
Ellipsometry
Manufacturers of optics, semiconductor and optical data storage share the same problem: how to control the thickness of thin films or layers? The measurement has to be fast,
Diode Lasers for Microlithography
Moore’s law is king: Striving for ever smaller structures is the clear target of microlithography. In modern microlithographic systems compact violet and UV diode
Lithography Optics Inspection
