Over the past decade, tremendous strides have been made in the design, manufacture and measurement of optical thin film filters. Driven in part from the challenging demands of fiber optic communication (telecom) filters, the manufacture of optical coatings has advanced significantly through improved optical monitoring technologies and algorithms; improved deposition technologies; and, very importantly, the ability to fully automate all aspects of the coating process. This improvement in optical coating technology has since been applied to filters used in other diverse fields ranging from bio-medical instrumentation to sensors to astronomy. In this paper, advanced optical thin film filters will be described along with their applications, both in telecom and spectroscopic fields.
