To study the optical properties of a skinny film, a tool named Microspectrophotometer is employed. Same properties ar studied for thick coatings over a micrometer region. different names of this device ar microreflectometer, micro-reflectometer, microspectrometer, densitometer (Spectroscopic), microspectroscopic photometer etc. Film Thickness
A actinic radiation visible photometer is employed because it covers from DUV to infrared ranges. the choice of vary depends on many factors like thickness of skinny film, thick coating and applicable wavelength vary for coefficient of reflection or coefficient.Film Thickness
This actinic radiation visible photometer is straightforward to work because it additionally has WINDOW primarily based software system. It's convenient to use setup and little table high style makes it most desirable and will increase its performance. This equipment permits getting reflection, transmission and absorption spectra in milliseconds. it's additionally appropriate to use for real time spectra and ratio direction. Film Thickness
The system comes with complete optical constants info and library for its user. It additionally facilitates user to use NK table or composite model (EMA) for individual film. The thickness up to 200mm of size may be measured mistreatment this.
