Quantization effects in nanolaminate structures of oxide materials are proposed and experimentally demonstrated only recently. Herein, the material combination of amorphous silicon and SiO2 deposited by magnetron sputtering is investigated and it is

A computer program simulating the deposition process with both broadband and monochromatic optical monitoring strategies allows to determine the most suitable parameters prior to deposition. This saves time and resources and is demonstrated using the

Various types of optical monitoring systems are established in industry. They range from single wavelength, over monochromatic to broadband monitoring to calculate a monitoring signal, which allows to terminate each layer in a filter at the required

Broadband monitoring with high signal quality enables using both broadband and monochromatic layer termination algorithms in the same coating run. Examples of a bandpass filter and an absorbing layer show the benefits of this “hybrid” approach.

A new optical monitoring system operating both in broadband and in monochromatic mode is presented. Measurement of transmission as well as reflection, directly on the substrate or on a test glass changer is possible. This system enables the user to c

We have shown that a simple process such as multiple repetition of an anisotropic sine/cosine average filter produces the effect of an excellent automatic adaptive filter for filtering speckle-interferometric phase fringe patterns. On an exemplary sh

The measurement of in-plane strain with image-shearing speckle pattern interferometry has so far been impeded by the lack of an efficient method for suppressing the out-of-plane displacement derivative. This paper presents a simple optical set-up wit

A simulation tool is presented for assessing the effectiveness of design reoptimization during the coating process. The simulations show significant differences between coating designs for bandpass filters, but only small differences for NIR blockers

In shearography a doubled speckle pattern is used to measure an approximation to the displacement derivative of a deformed object. In this paper a method is presented that reconstructs the original displacement field from a shearographic recording. T

In this work we want to demonstrate how the methodology of Design of Experiment (DOE) can be used for the development of ion-assisted ITO films deposited at low temperatures. The optimization method allows us to identify the process parameters, which
