- Pinholes in optical coatings can dramatically degrade performance of interference optical filters, particularly for the application of liner variable filter or laser protection which requires high optical density. Modelling and simulation of effect of pinholes, thickness uniformity, thickness control error on performance of optical filters revealed that pinholes are the main issue. Our developed pinhole-free/minimised sputtering process allowed for high-quality optical coatings. This work provided a foundation for further optical filter development, for example, liner variable filter (Patent WO2018150173A2) and bandpass filter for gas sensors and miniaturised spectrometer which are now the products for UWS spinout company Albasense.
