There are many specialized devices which are used for measuring the thickness of a film. There are number of optical instruments that provide an easy solution to find the exact thickness of a thin film and thick coating thickness. These solutions are very useful for studying the interior surface behavior of a thin film. These solutions are also very helpful in determining the alloy concentration across the surface.
Film thickness gauge is one of the most useful device that helps to measures the dimension of film and comes with many other features. It registers the film thickness and measures the refractive index of film up to five layers. It is also capable of handling different geometry as well as mapping patterns for example square linear, polar etc.
This gauge is used in many applications such as LCD, semiconductor fabrication, optical coatings, biological materials etc. It also contains array based detector which is helpful in making the measurement process much faster.
Various scientists uses an instrument called UV visible spectrophotometer for studying the optical properties of a substance. This tool is best suited for examining refractive index and real time spectra. The main advantage of this tool is that it is easy to operate and it has a small table design at the top. Even this tool has a special feature of two-dimensional and three-dimensional output graphics and it can be modified for any particular applications.
