The Filmetrics® F60-t family maps film thickness and index just like our F50 products, but it also includes a number of features intended specifically for production environments. These include automatic notch finding, automatic on-board baselining, an enclosed measurement stage with motion interlock, and an industrial computer with pre-installed software. The different F60-t instruments are distinguished primarily by thickness and wavelength range. Generally shorter wavelengths (e.g. F60-t-UV) are required to measure thinner films, while longer wavelengths allow measurement of thicker, rougher, and more opaque films.
