This tool is for thickness and optical property measurements of films on substrates. The technique used is white light reflection. Data is taken with normal incidence reflection of white light (400 nm – 850 nm) from the surface. The data is modeled and the optical parameters are adjusted to give a best least-squared fit to the data. The accuracy of the technique will depend on the thickness of the film and the optical models used for the fitting of the data. For a more complete description go to [http://www.filmetrics.com/ Filmetrics]. |

This tool is for thickness and optical property measurements of films on substrates. The technique used is white light reflection. Data is taken with normal incidence reflection of white light (400 nm – 850 nm) from the surface. The data is modeled and the optical parameters are adjusted to give a best least-squared fit to the data. The accuracy of the technique will depend on the thickness of the film and the optical models used for the fitting of the data. For a more complete description go to Filmetrics.
