Filmetrics has announced the web’s most complete public database of
refractive index values for use in thin film
thickness measurements, as well as a free refractive index
measurement service. Without accurate refractive index values for each
material being measured, optical-based thickness
measurements are inaccurate or even impossible.
The new database and measurement service are finding use across a broad
range of applications, including many in the semiconductor, solar,
display, and biomedical industries. Filmetrics President Dr. Scott
Chalmers stated, “The first full week our database was online it
averaged over 200 visitors a day. This demonstrates the large number of
people requiring this information to perform their job.”
Filmetrics instruments determine film thickness by illuminating the film
with white light and measuring the spectrum reflected off of the film.
The wavelength ranges are available between 200-1700 nm. Once the
spectrum is collected, the Filmetrics software analyzes it to determine
thickness, optical constants, and other user-selectable parameters.
