Therefore optical coatings have a long history of research and development, which is still advancing. For this thesis optical filter design and fabrication methods utilizing vacuum evaporation and optical monitoring were studied. The objective was to test and improve production capabilities of an industrial electron beam evaporation system using direct transmittance measurement for layer thickness monitoring. Four distinct optical coatings of differing complexity were designed and fabricated. The coating types were a Bragg mirror, a short wavelength pass edge filter, a long wavelength pass edge filter and a narrow bandpass absorption filter. Design processes for the filters are shown including their structure and the development of the monitoring strategy. The results are analysed and possible optimization solutions are shortly discussed.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2019-07-11T09:33:16Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-07-11T09:33:16Z (GMT).
