This application note describes the challenges related to the optical testing of thin film filters (TFF). TFFs are probably the most versatile and widely used optical components, and yet come with unique challenges when it comes to optical testing. TFFs are free-space optical components that consist of a substrate (typically glass) coated with a succession of layers of high and low index materials that give the TFF its desired transmission and reflection profiles
