Precise control and adjustment of uniformity for optical coatings on 2D and 3D components Open
The uniformity of a PVD coating process is investigated and adjusted in this work. With the help of a digital twin derived from physical modelling of the plasma and gas flow dynamics in the reactor, it is possible to precisely predict and …

Uniformity and wavefront control of optical filters Open
The present paper addresses uniformity effects in demanding dielectric optical coatings. The origins of spectral resonant wavefront errors (WFE) induced by non-uniformities in complex dielectric filters are investigated in detail. The coat…
