Thin film optical filters, also called thin film filters or TFFs, filter or modify lightwaves within an optical system to meet the phase control needs of different optical applications. Example applications include photolithography, image enhancement, image splitting, color match imaging and Raman spectroscopy. Thin film optical filters are used across many industries, including aerospace & defense, medical, and electronics.
Common thin film deposition methods for optical filters or TFFs are ion assisted e-beam evaporation, magnetron sputtering, and ion beam sputtering. We offer solutions for each type of deposition: choose the Integrity for ion assisted e-beam evaporation, choose the Discovery for magnetron sputtering, and the Infinity IBD for ion beam sputtering.
